Who was the first person to classify organisms into two groups
The first person to classify organisms into two groups was Aristotle, but Lineu was recognized as the father of taxomy
Who were the main scholars of biological classification?One of the central figures in the history of biological classification was the Swedish naturalist Carl von Linné, popularly known in our country as Linnaeus (1707-1778). His classification system encompassed all organisms and was based on the similarities between them.
Moreover, Aristotle, as far as is known, was the first to classify living beings. He divided them into two groups: animals and plants.

What happened if the temperature was too high for enzymes
If the temperature was too high for enzymes they would be denatured which is why they have optimum temperature they work with.
What is Denaturation?This occurs when the structure of a protein is modified as a result of various factors.
Such factors include high temperature which results in the structure being changed and leads to the enzyme losing some properties needed for action.

Beverly and Carl are in a race. Their graphs show the data.
A graph with horizontal axis time (seconds) and vertical axis velocity (meters per second). An orange line labeled Beverly starts at 0 seconds 0 meters and goes straight to 10 seconds 15 meters and then to 50 seconds 35 meters. A blue line labeled starts at 0 seconds 0 meters and goes straight to 10 seconds 10 meters and then to 50 seconds 30 meters.
Which best describes the race?
Even though for a majority of the race they accelerated at the same rate, Beverly won because hethe r initial acceleration was greater than Carl’s.
How, explain your answer?The given parameters are listed as follows:
For Beverly: initial time of motion, t₁ = 10 s
initial velocity, u = 15 m/s
final time of motion, t₂ = 50 s
final velocity, v = 35 m/s
For Carl: initial time of motion, t₁ = 10 s
initial velocity, u = 10 m/s
final time of motion, t₂ = 50 s
final velocity, v = 30 m/s
In summary, Beverly and Carly had the same average acceleration for the majority of the race but the initial acceleration of Beverly was higher than that of Carl, hence Beverly won the race.

Dihybrid crosses
1. In man, assume that spotted skin (S) is dominant over non-spotted skin (S) and that wooly hair (W) is dominant over non-wooly hair (W). cross a marriage between a heterozygous spotted, non-wooly man with heterozygous wooly-haired, non-spotted woman. Give genotypic and phenotypic ratios of offspring?
Explanation:
The phenotypes and genotypes of the progeny can be determined by a dihybrid cross of the parents.
The heterozygous male will have the genotype 'SSww' and the heterozygous female will have the genotype 'ssWW'.
When crossed, the F1 offsprings will have a hybrid genotype of 'SsWw'. These offsprings are heterozygous with spotted skin and wooly hair.
On self-crossing of the F1 hybrids, we find four different combinations of the alleles- SW, Sw, SW and sw. The probability of getting each of these combinations is 1/4.
Hence, the probability of any dihybrid type is 1 out of the 16 possible genotypes. Using Punnet square, we find
9 SSWW: 3 SSww: 3 ssWW : 1 ssww
This is the phenotypic ratio of the offsprings.
The ratio of the possible genotypes will be 1:2:1:2:4:2:1:2:1.

The heterotropic effect is the effect of molecules other than substrate on allosteric enzymes.
What is the heterotropic effect?
The term "allosteric enzymes," which derives from the Greek "allo," which means "other," refers to enzymes that have a second site in addition to the active site. Enzymes can have many allosteric sites, which are these. They stand out because they can react to many circumstances in their immediate surroundings.Unrelated to the enzyme's substrate, a regulatory molecule is referred to as a heterotropic allosteric effector. The enzyme binds to can either be activated or inhibited by it.Carbon dioxide ([tex]CO 2[/tex]) is an excellent example of a heterotropic allosteric effector because it also functions as an effector of hemoglobin but is not an enzyme-substrate.To learn more about allosteric enzymes refer to: https://brainly.com/question/13150990

As an individual ages, new neurons and dendrites appear, but others atrophy. Compared to when they were adolescents, adults have fewer neural connections and their brain size _____ as they continue to age.
The brain and central nervous system shrink as we age.
What happens to the brain when we age?The brain is one of the most important organs in our body because all the nerve signals are produced there for our body to function.
In the brain we find nerve connections through neurons. A particular aspect of them is that during childhood and adolescence they multiply as we learn new things.
However, once we reach the stage of old age, these nerve connections deteriorate and are reduced, therefore, the size of the brain and the central nervous system decreases.

Why is there competition in nature?
A. Living organisms are influenced by abiotic factors.
B. Ecosystems are composed of habitats and communities.
C. There are more living things than there are resources to support them.
D. Environments are constantly changing as organisms interact.
Answer:
c
Explanation:
Competition exists in nature due to the limited availability of resources compared to the abundance of living organisms. This creates a struggle for survival and dominance among species, leading to an ongoing process of natural selection. Thus, correct option is C.
Because there are more living things than there are resources to support them, competition is a natural phenomenon. There is a limited supply of food, water, shelter, and other survival-related essentials in the Earth's ecosystems. As a result, in order to meet their demands and ensure their survival, organisms must contend for these scarce resources.
This rivalry is essential to the process of natural selection because it increases the likelihood that organisms with beneficial characteristics or adaptations will survive and pass on their genes to the following generation. Because only those with the strongest adaptations flourish in a certain habitat, this eventually drives the evolution and specialization of species.

What is a spring tide? When and why does it occur?
Answer:
Spring tides happen just after every full and new moon, when the sun, moon and earth are in line. That's when lunar and solar tides line up and reinforce each other, making a bigger total tide.
A spring tide occurs when there's a new or full moon. Because it follows the moon's lunar cycle, a spring tide happens twice per month. With the moon and sun roughly aligned the tides of Earth are on average slightly larger than usual.

A particular plant has two alleles that control the length of its stem. T represents the dominant allele that codes for a tall stem, and t represents the recessive allele that codes for a short stem. Based on the Punnett squares, which two statements are true about the genotype of the plant’s stem length?
First Generation
__t_ t
T Tt Tt
T Tt Tt
Second Generation
__T_ t
T TT Tt
t Tt tt
Select all the correct answers.
A) Plants with short stems are homozygous for that trait.
B) Plants with tall stems are always homozygous for that trait.
C) Both parent plants in the second generation are heterozygous.
D) Both parent plants in the second generation are homozygous.
The correct answers are options A and C.
How, explain your answer briefly?The Statement A says that the plants, which have a short stem is homozygous for the trait. According to the question, the allele for the short height is recessive. A recessive trait can only be observed, when the dominant allele is not at all present. Hence, the plant must have tt allele, so, the plant having short stem would be homozygous recessive.
The statement C says that the both parents in second generation are heterozygotes. It is given that the parents in the second generation have aa genotype Tt. In this case, both the alleles are different, hence, the parent plants are heterozygotes.
Thus, this could be the answer.
