Explanation:
While their unique evolutionary paths have led to different adaptations, non-vascular and vascular plants are commonly found occupying similar habitats and together play an important role in establishing community structure and biodiversity. Compare and contrast how they interact together in this particular ecosystem, and the role their unique adaptations have played in forming the above relationships (Compare and contrast at least 2 relationships). What happens to these interactionsifwe lose just one species
Answer:
Non-vascular plants provide nutrients, avoid erosion and habitat to animals.
Explanation:
Non-vascular plants has played an important role in the ecosystem and biodiversity because it releases various nutrients in the soil which can be used by the vascular plants from the soil and also reduce erosion of the soil. These non-vascular plants provides habitat and food to various animals in the ecosystem. If the non-vascular plants can be removed from the ecosystem, the whole ecosystem will be disturbed and adverse effect on vascular plants and animals occur.
How are humans impacting biodiversity in ecosystems around the world? Provide two examples to support your claim.
Answer:
as humans population continues to grow, we're cutting down more trees and occupying more lands to suffice the need of citizens, therefore, decreasing the forest biodiversity. Our plastic bags, as well as wastes, are polluting the ocean and eradicating essential species that are required to sustain a balance ecosystem, therefore, decreasing the biodiversity of the ocean that are required to maintain a balance environment.
Human activities have affected in Biodiversity in the ecosystems negatively and such activities include : i) Indiscriminate hunting/fishing ii) Improper waste disposal
Humans in search of food ( meat ) engage in excessive/indiscriminate hunting of endangered species thereby reducing the Biodiversity of animal species present in the wildlife also excessive fishing activities affects the biodiversity of certain species of fishes in our oceans negatively.
When wastes are not properly disposed they degrade the environment and decrease the biodiversity of the ecosystems in the process. the burning of industrial wastes leads to the exposure of certain species to the negative effects of dangerous gases and liquids thereby making the ecosystems to become unbalanced.
Hence we can conclude that some of the human activities impacting biodiversity in ecosystems around the world include : Indiscriminate hunting/fishing and Improper waste disposal

Color in poison dart frogs is controlled by a single gene with multiple alleles. A blue poison dart frog that is heterozygous for the blue allele (Cb) and red allele (Cr) is crossed to a yellow poison dart frog that is heterozygous for the orange (Co) and yellow (Cy) alleles. Their progeny are 1/2 blue, 1/4 orange, and 1/4 yellow. Determine the order of dominance for the alleles. (Order of dominance is indicated as: A > B > C > D such that A is dominant over all alleles, B is dominant over C and D, C is dominant only to D, and D is recessive to all alleles.)
Answer:
Cb>Cy>Co>Cr
Explanation:
First of al we need to do the Punnett square. As a result we get the genotypes:
CyCb
CyCr
CoCb
CoCr
Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.
Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.
The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.
As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.

what functions do pseudopodia perform for an Amoeba?
Pseudopodia are an example of blunt transient processes employed by cells such as amoeba or the neutrophil leucocyte for locomotion and the uptake of food particles and /or other extraneous matter.
Pseudopods have two main functions: (1) locomotion and (2) capture of prey or engulfing of food. For instance, amoeba can crawl by extending the cytoplasm and the contraction of the filaments. The pseudopodbulge outward from the edge of the cell to pull in the entire organism as it goes forward.

The hypothalamus regulates the ________.
a. thalamus
b. pineal gland
c. pituitary gland
d. pons
Answer:
c. pituitary gland
Explanation:
The hypo(below) thalamus is an almond size structure located superiorly to the brainstem. it is located below the thalamus. Hence the name hypothalamus.
It is primary function is is to control the body homeostatic functions of sleeping and waking up, sex, thirst and hunger etc.
It performs these roles by serving as the primary link of the nervous system with the endocrine system. Pituitary gland is an example of endocrine gland that secrets many hormones. (they are called endocrine because the hormones are secreted directly into the blood streams.
Its activities are controlled by the nervous stimulation from hypothalamus. Therefore the instructions to secretes certain hormones to the post and anterior part of the pituitary gland depends on the hypothalamus.
Growth hormones, oestrogen, and thyroid are examples of hormones of the pituitary glands.

why does breathing rate increase during excercise?
Answer:
When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

In humans, freckles are a trait that exhibits simple dominance. The two alleles for this trait are freckles (A) and no freckles (a). A freckled man whose mother has no freckles marries a woman with no freckles. What is the probability that their first child will have freckles? Use the Punnett square to show your work.
Answer:
50 percent
Explanation:
Aa goes with aa
so their children's genotypes would be
Aa Aa aa and aa
so two with freckles and two without freckles which is why their first child has a 505 chance of having freckles
hope this helps :)
The probability of having a freckled child is 50%. because half of the children will have the genotype Aa, which is freckled, and half will have the genotype aa, which is no freckles.
What is a punnett square?A Punnett square is a tool used to predict the probability of an offspring having a particular genotype (genetic makeup) based on the genotypes of its parents. To create a Punnett square, we use the alleles of the parents and place them into a grid, with one allele from one parent on the top and the other allele from the other parent on the left-hand side.
In this scenario, the father has a genotype of Aa (freckled) and the mother has a genotype of aa (no freckles). The mother only has the recessive allele (a) and the father has both dominant (A) and recessive (a) allele.
The probability of having a freckled child is 50%. because half of the children will have the genotype Aa, which is freckled, and half will have the genotype aa, which is no freckles. The dominant A allele will mask the recessive a allele and make the offspring freckled.

A. What length of time is best to use for the firing of pottery to make it strong?
B. How many needles grow on the giant redwoods in California?
C. What color of carnation flowers do people find most attractive?
D. What is the most number of points ever scored in a professional basketball game?
Answer:
A. What length of time is best to use for the firing of pottery to make it strong?
Explanation:
Point A
What length of time is best to use for the firing of pottery to make it strong?
This is a scientific question for Nancy since while making pots from black mud, it is very important to know how much time is required to fire the pot in order to make it strong. Because if we fire it for too long the pot may be become too hot and will eventually crack. While if we fire for less time it will not become hard enough to withstand its shape. So knowing the proper time to fire the pot is very essential in pottery.
Point B, Point C and Point D are not scientific investigations since it includes ones likes and dislikes, quantities and numbers of goal scored which is not scientific.
Hence, option A is the correct answer.

a. anaerobic metabolism
b. lactic acid metabolism
c. aerobic metabolism
Answer:
The correct answer is a. anaerobic metabolism.
Explanation:
Anaerobic metabolism refers to a high intensity of exercise in which the absence of oxygen limits performance due to the accumulation of metabolites and the corresponding metabolic and physiological dysregulation.Predominantly anaerobic exercises are characterized by: high intensity and short duration, energy is obtained from immediate sources such as muscle ATP, phosphocreatine (PC) and glucose and does not need oxygen for this. For very explosive or high intensity movements it is necessary to obtain a powerful and fast energy, this is obtained by anaerobic systems. The anaerobic metabolism is able to respond immediately to the energy demands of physical exercise and can provide energy for very high intensity exercises (strength and / or power). But this system has a limited capacity, it is short-lived, so if the exercise continues, either you have to stop due to fatigue or reduce its intensity (the power developed) to a level where energy can be obtained through the aerobic metabolism.
