Which of the following facts supports the argument that a pregnant cow should be fed more in its last trimester?
The placenta is formed by the end of the first trimester
The heart beats and organs are formed during the first trimester.
Teeth and fur develop during the second trimester.
Three-quarters of all growth occurs during the third trimester.
Answer:
Three-Quarters of all growth occurs during the third trimester.
Explanation:
D is the only option that has anything to do with the last trimester which is what the question was asking about. Furthermore, because so much growth is occurring during this time the cow will need more food to support this growth. So, D is the best option.

Select the two correct statements. Select the two correct statements. All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.
Complete question:
Comparisons of amino acid sequences can shed light on the evolutionary divergence of related species. If you were comparing two living species, would you expect all proteins to show the same degree of divergence? Select the two correct statements.
All proteins will show the same degree of divergence because they are modified with the same rate of evolution. All proteins will show the same degree of divergence because different species experience the same selection pressure. All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.All proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism.Answer:
3) All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.
4) All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways.
Explanation:
All proteins will show the same degree of divergence because they are modified with the same rate of evolution. FALSE. All proteins will show the same degree of divergence because different species experience the same selection pressure. FALSEAll proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure. TRUE All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. TRUEAll proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism. FALSEAll proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism. FALSE.In this example, we are comparing different species, although we do not know how different they are. Changes in the proteins reflect the divergence between groups during evolution. Among different animals and plants, changes in proteins and their following maintenance can be associated with a group divergence and evolution.
The same proteins amino acid sequences in different species provide information about the divergence point between both species. Probably, the origin of genes and protein changes and the subsequent fixation of those changes by natural selection is the cause of most of the phenotypic variation observed between species. So, genes and proteins are subdued to selective pressures that vary according to the environment and the species.
In populations of the same species inhabiting different places with different environmental characteristics suffer changes that respond to their life habits. Proteins evolve in different degrees and take different routes, influenced by the selective pressures of the environment surrounding them. Ecological, behavioral, reproductive pressures, among others, vary between populations according to their own needs and produce changes that "model" the organisms when fixating. These changes are inherited generation after generation, leading to a divergence in the species.
Brown-eye color is dominant and blue-eye color is recessive. A brown-eyed man marries a blue-eyed woman and they have a son that has Green eyes. SC.912.1.16.1
What Pattern of inheritance is that?
sex-linked
Co-dominant
Incomplete dominance
O polygenic recessive
Answer: Polygenic recessive
Explanation: Because polygenic dominance describes a relationship between the alleles of a polygenic trait where some alleles are dominant and others are recessive.
This is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).
What is Polygenic inheritance?Polygenic inheritance can be described as the inheritance of traits that are governed by different genes and not just a single gene, and can also be referred to as non-Mendelian inheritance, where traits run like a bell. distributes the sizes and shows the different combinations such as dominant and recessive alleles.
Polygenic traits express several different phenotypes, or displayed characteristics where this inheritance is a type of incomplete dominance inheritance, where the expressed phenotype is a mixture of inherited traits.
Thus, this is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

______ plants are important in fixing nitrogen.
a. Legume
b. Berry
c. Nut
d. Poisonous
Answer:
A
Explanation:
Legume plants are important in fixing nitrogen. Therefore, the correct option is A.
Beans, peas, lentils and clover are examples of leguminous plants that are important for nitrogen fixation. They co-exist well with rhizobia, a type of bacteria that fix nitrogen. These bacteria live in nodules on the roots of legumes and use a process called nitrogen fixation to convert atmospheric nitrogen into a form that plants can use.
Legumes can obtain substantial amounts of nitrogen, an important nutrient for plant growth, without being entirely dependent on soil nitrogen, because of their ability to fix nitrogen. Legumes play an important role in agriculture and ecosystems, by adding nitrogen to the soil and increasing its fertility. Legumes are valuable crops because of their high protein content as well as their ability to improve soil health by fixing nitrogen.
Therefore, the correct option is A.

The rate limiting reaction of aerobic respiration involves the phosphorylation of __________ by the enzyme _______ . The rate at which this enzyme makes product is ___________when ATP levels rise because the molecule ___________binds to an _________ site on the enzyme and acts as a(n)_________ . When ATP levels fall ________ binds to ________of ____________. This interaction leads to an increase of cellular ___________ , so that this is a n example of a ___________ feedback loop.
Answer:
Explanation:
The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.
An aerobic respiration can be defined as a chemical and biological process that involves the use of oxygen in living organisms to make energy (ATP) from carbohydrates (sugars) during cellular respiration.
This ultimately implies that, an aerobic respiration can take place or occur in the presence of oxygen.
What is an enzyme?An enzyme can be defined as a biological catalyst that typically speeds up (accelerates) the rate of a chemical reaction, especially by lowering the activation energy of its chemical reactants.
Factors that affects an enzymeThere are four (4) main factors that affect the actions and the rate of an enzyme and these include the following:

Offspring
Which prediction about the offspring's body color is based on the properties of genetic reproduction?
O A The offspring can only express the trait of gray body color.
OB. The offspring can only have genes for the trait of gray body color.
O c The offspring can express either the gray or the black body color trait
O 0. The offspring are equally likely to have genes for the gray or black body color trait.
The prediction about the offspring's body color is based on the properties of genetic reproduction, it can only express the trait of gray body color. The correct option is A.
What is the dominant and recessive gene?Recessive and dominant genes. Dominant/recessive interactions are the most frequent type of allele-allele interaction. When one (dominant) allele of a gene effectively outweighs the other (recessive) allele, the allele is said to be dominant.
Blood types and eye color are two instances of dominant/recessive gene interactions. Due to recessive inheritance, the disease can only be brought on by a pair of faulty genes. Carriers are individuals who have only one faulty gene out of the pair.
Therefore, the correct option is A. The offspring can only express the trait of gray body color.
