As a result, your body might not absorb and benefit from the minerals, vitamins and fats that you take in, thus making the body more vulnerable to infections.
Which option uses the monitoring method to check the growth of invasive species?
a. Digging of the species
b. Tilling the land
c. Spraying pesticide
d. Cleaning of ship ballast
Answer:
The answer is A
Explanation:
Invasive species are species that thrive unregulated in an introduced environment/ habitat and affect the biodiversity of the environment. They boom unchecked mostly due to lack of a natural predator. Therefore, introducing a predator will limit their growth.
The option that uses the monitoring method to check the growth of invasive species is digging of the species. Thus, the correct option is A.
What are Invasive species?Invasive species may be defined as those species of organisms that cause ecological or economic threats in a new environment where it is not native.
The invasive species harm the biodiversity of new habitats significantly. In order to prevent this, the specific predators of such species are introduced.
The process of digging of the species also helps in monitoring the growth of invasive species.
Therefore, the correct option for this question is A.

Explanation:
1) Evergreen are seedlings that keep their leaf in all periods and include pine, cedar, and mango trees.
Evergreen is a plant that stays all year round and is still green. There are many various types of juniper plants, including shrubs and trees. Evergreens have many coniferous species (such as fir, hemlock, blue spruce, red cedar), and mango.
2) Hardwoods replicate with petals and also have wide leaves, like mango, elm, and maple.
Hardwoods are created by polymer science in which flowers replicate and have large leaves. A number of plants are nocturnal. Some of the temperate climates lose their leaves each fall as rates drop and inactive in winter, and those of tropical areas will shed the leaf in reaction to temporary or intermittent shortage times.
3) Conifer leaves are stiff and syringe-like in particular, while seedlings are encompassed in cones. The conifers include cedar and pine.
Gymnosperms are conifers. They are cone-bearing seedlings with plant tissues, fruiting trees are all live evergreens.

A woman with hemophilia and a man without hemophilia get married. What are the chances that their first child will have hemophilia?
75 percent
50 percent
25 percent
100 percent
Answer:
50 percent
Explanation:
Hemophilia is a disorder in which blood doesn't clot normally.
Lets consider Xn as hemophilia gene.
So woman affected with hemophilia will have XnXn gene and man not affected with hemophilia will have XY gene.
When they both undergo crossover, genes in child will be XXn (girl -carrier), XXn (girl -carrier), XnY (boy-affected) and XnY (boy-affected).
Parent Gene:
XnXn (affected woman)
XY (Man not affected)
After crossing over - children gene for first generation:
XXn (girl-carrier) XXn (girl-carrier) XnY (boy- affected) XnY (boy- affected)Hemophilia is a X - linked recessive disease which means women are only carrier for this disease untill or unless both the X genes are hemophilia gene and man have more chances to get affected as they have only one X - linked gene.
It means 2 out 4 children are affected.
So, there are 50 percet chances that their first child will have hemophilia.

Explanation:
Arrange the following substances in order of increasing tendency to donate electrons
with reasons:
α –ketoglutarate, Oxaloacetate, O2, NADP+
, Malate
Answer:
α- ketoglutarate → NADP+ → Oxaloacetate → O2.
Explanation:
The ability of an molecule or a compound to donate or accept electron can be related to their electron affinity.
The more positive the electron affinity is ; the more likeliness such compound is known to be as an electron acceptor which accepts . Also the less positive the electron affinity is the more likeness such compound will be known to be as an electron donor which donates electron
The electron affinity of a compound to accept or donate electron can be related to their reduction potential value (Redox Value).
From the information given ; we have α –ketoglutarate, Oxaloacetate, O2, NADP+ and we are to arrange in an increasing tendency to donate electrons.
i.e from the least tendency to donate electron to the highest tendency to donate electron.
The reduction potential value (Redox Value) of the compounds and molecule given are:
α –ketoglutarate ---> - 0.38 since α- ketoglutarate will react with CO2, it gives isocitrate
Oxaloacetate ----> - 0.18 since Oxaloacetate will react with two moles of hydrogen ion and electrons respectively to give Malate
O2 ------> + 0.82 since O2 will react with 4 moles of hydrogen ion and electrons respectively to give 2 moles of water
NADP+ ------> - 0.32 since NADP+ will react with two moles of electrons and one mole of hydrogen ion to give NADPH
Again; lets recall the less positive the electron affinity is the more likeness such compound will be known to be as an electron donor which donates electron.
So to arrange the given substances in order of increasing tendency to donate electrons since we've known their standard reduction potential value (Redox Value); we have the increasing order as:
α- ketoglutarate → NADP+ → Oxaloacetate → O2.

Kant's famous First Formulation of the Categorical Imperative reads:Act only according to that maxim whereby you can at the same time will that it should become a universal law. Kant taught morality as a matter of following maxims of living that reflect absolute laws. "Universal" is a term that allows for no exceptions, and what is universal applies always and everywhere.Lying, for any reason, is universally wrong. Be sure to listen to Kant's audio lecture before posting this week! So, consider the famous case of the Crazed Murderer. In your town the Crazed Murderer comes to your door looking for your friend and wanting to kill him.You know that your friend went home to hide. What do you tell the murderer? When he leaves and runs up the street to your friend's house, what do you do?
Answer:
Universal laws are the ethics that guide the behavior of humankind. These laws are universally accepted by all humans and are followed by them in their daily lives. Law of attraction, the law of vibration, is some of the examples of universal law.
Explanation:
Kant believed that telling a lie is wrong, and murdering a human is a crime. All humans should follow these two principles. Keeping in mind the words of Kant, in the given situation, I will not tell the murderer about the exact location of my friend. I will not remain silent also because that crazy man could kill me too. Instead of telling him the right directions, I will tell him the wrong directions and will send him to the wrong place so that he would not harm my friend and me. Though telling a lie is wrong but saving two lives will be more important to me in this situation.
As soon as the murderer leaves, I will call the police and will tell them the direction in which the murderer has gone. This will save me as well as my friend's life, and the murderer will also get punishment for his sin.
Hope this helps!!

You are studying primates in West Africa and discover a small population of monkeys in an isolated forest. They resemble a species that lives about 50 kilometers away, across a river. The main difference appears to be white tufts of fur underneath the ears in the new population you've found. What evolutionary mechanism probably explains this difference?
Answer:
Geographical isolation
Explanation:
The evolutionary mechanism that can probably explain the difference, in this case, is geographical isolation.
Geographical isolation represents one of the reproductive isolation mechanisms - an array of physiological and behavioural processes that leads to speciation in living organisms.
Geographical isolation refers to the separation of organisms of the same species in terms of physical geographical features such as distance, mountains, water bodies, etc. The separation causes each group to take different adaptive paths, eventually leading to speciation, that is, they become separate species.
In this case, the small population of monkeys in the isolated forest must have been geographically isolated from their counterparts in some ways back. They took a different adaptive path from the larger group as a result of geographical difference and eventually became a new species.

The absence of which of these will not affect photosynthesis is - oxygen, Carbon dioxide, water, Chlorophyll, light. Give reason
Answer:
Oxygen
Explanation:
Oxygen is the by product of photolysis during photosynthesis whereby water molecules are split to form protons (H+ ions), electrons and oxygen (by product).
Oxygen is not needed during any of the reactions in photosynthesis and Calvin cycle and will not affect the rate of photosynthesis or possibility of photosynthesis occurring. However, it will affect the process of aerobic respiration instead.
Carbon dioxide is needed in carbon fixation during the Calvin cycle. Without it, 6 carbon sugars cannot be formed.
Water is needed for photolysis to produce protons (maintain the electrochemical gradient) and electrons (to replenish lost electrons)
Chlorophyll are pigments that harvest light energy to excite electrons produced from photolysis of water to be passed down the electron transport chain.
Light is needed as a source of energy to energise the electrons
a. What are general/biological functions of proteins in human body/cells/organism?
b. What is the building block of proteins? Draw the general structure of this building block and write the names of functional groups in the structure?
Answer:A) proteins are useful as enzymes, hormones etc.
B) the building block of protein are amino acids
Further explanation below
Explanation: A) proteins are polymers formed by several chains of amino acids. They occur in living tissue and form 50 -- 60% of the total dry mass of the living cell. Proteins found in the membrane are used as structural integrity. Some proteins are catalytic in nature and are such are used as enzymes. They also occur as hormones. Proteins help in the transport of substances across the cell membrane, when they are found in the cell membrane.
B) the building block of protein are amino acids. They undergo condensation reaction to form proteins.
The structure of amino acid is in the attached photo.
R = the group that determine the name of the amino acid. It may be a hydrogen atom,an alkyl, an aryl, or carboxyl group.
H2N = the amino group
COOH = the carboxyl group
C = the alpha central carbon to which other groups are attached.

You are a brilliant student who has discovered a new genetic disease identified by the absence of a key enzyme involved in the Krebs cycle. You work diligently to discover that the missing enzyme is produced in the cytoplasm as a zymogen, but does not get to its correct location in the mitochondria. What is the problem?
Group of answer choices
the signal peptide on the N-terminus of the protein may be incorrect or missing
the functioning of the Krebs in the matrix
enzymes allow some reactions to occur but not others
dephosphorylation did not occur
Answer:
The correct answer is that on the N-terminus of the protein the signal peptide may be missing or incorrect.
Explanation:
The metabolic reactions of several enzymes that take place within the mitochondria are generated with the assistance of genes produced within the nucleus. The translation of these gene products takes place within the cytoplasm and is targeted towards the mitochondria.
In case, if a flaw is witnessed at the time of targeting towards the mitochondria, the protein would stay within the cytoplasm and will not move forward. Therefore, error in the signal peptide would be the correct option.
True or False?
Diatoms lack a flagellum.
Answer:
True
Explanation:
Diatoms are unicellular (one celled) algae. They undergo photosynthesis to produce their own food. They are found in many different marine and aquatic environments and ecosystems.
Diatoms do not move. They don’t have cilia or flagellum, which would allow them to move around and swim.
Therefore, it is true that diatoms lack a flagellum.

The presence or absence of horns in ruminant livestock species is determined by the polled gene. The polled allele (P) is dominant to the horned allele (p). What genotype(s) would result in an animal being polled (having no horns)?
Answer:
PP and Pp
Explanation:
The dominant allele "overpowers" the recessive allele, therefore that trait shows. In this case, it is the polled allele. Therefore, the heterozygous pair works. Also, the homozygous pair with only the dominant allele (polled) will of course work since that is the only gene.
The genotype(s) would result in an animal being polled (having no horns) is PP and Pp.
An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual possesses in a certain gene or genetic region are also referred to as the genotype.
The genotypes that encode for the polled allele are PP or Pp because the polled gene (P) is dominant over the horned gene (p). Because both of these alleles must be recessive in order for the horned allele to be expressed, the genotype that will carry it is pp.
