Kinetic energy is absorbed and converted to potential energy in an endothermic reaction.
The statement is true about endothermic and exothermic reaction is Kinetic energy is absorbed and converted to potential energy in an endothermic reaction.
What is an endothermic reaction of an example?The reactions or changes in physical state that absorb heat are called endothermic processes. An example of an endothermic reaction (the prefix “endo” means “into”) is the cooking of food, in which energy is required.
An endothermic reaction is a chemical reaction whose total energy (enthalpy) of its products is greater than that of its reactants, that is, it absorbs energy (in the form of heat).

A. the expression of a dominant phenotype in a heterozygote.
B. the increased expression of a particular trait when a hybrid species is formed.
C. the expression of one gene masking the effects of another gene.
D. quantitative traits that diminish or intensify a particular phenotype.
E. the influence of environment on the expression of a particular genotype.
Answer:
the influence of environment on the expression of a particular genotype.
Explanation:
In genetics, we define penetrance as the proportion of individuals in a given population carrying a particular gene/allele which leads to the expression of the particular trait associated with that gene/allele.
Expressivity is defined as the degree of expression of a given phenotype by individuals who possess a particular genotype. Expressivity shows the extent of variation in expression of genes by individuals having a particular genotype.
Both penetrance and expressivity has to do with the influence of environment on the expression of a particular genotype.

Describe a large water cycle that takes a long time to complete.
Answer:
the longest water cycle to complete is rain because rain is
water
The water cycle, also known as the hydrologic cycle, is the process by which water continuously moves through the earth's atmosphere, land, and oceans. It is a large, complex cycle that takes a long time to complete, with some parts of the cycle taking thousands or even millions of years.
What is the water cycle?The water cycle starts with the evaporation of water from the earth's surface, primarily from the oceans but also from lakes, rivers, and other bodies of water. The evaporated water rises into the atmosphere, where it cools and condenses into clouds. The clouds eventually release their moisture as precipitation, which can fall as rain, snow, or sleet. Some of the precipitation is absorbed by plants and animals, while some runs off into streams, rivers, and oceans. This process is known as runoff.
Hence, The water cycle, also known as the hydrologic cycle, is the process by which water continuously moves through the earth's atmosphere, land, and oceans.

The complementary mRNA sequence for AAGTCA is:
A) TTCAGT
B) UUCAGT
C) UUCUGT
D) UUCAGU
E) TTCAGU
Answer:
UUC AGU
Explanation:
To find the complementary mRNA sequence you need to match each base of the DNA to the complementary base on the RNA. In DNA, A matches T and G matches C. However, the base T is not found in RNA, instead, it is replaced with U. So in mRNA, A matches to U. Finally match each base up to get UUC AGU.
In a population of a certain fish, the gene for fin size has two alleles. The dominant allele leads to large fins, and the recessive allele leads to small fins. Genetic tests on this population show that the frequency of the recessive allele is 0.91. What is the frequency of the dominant allele
Answer:
0.09
Explanation:
A locus can be defined as a specific genetic location for a particular gene variant (i.e., allele). Diploids organisms (e.g., humans) have two sets of homologous chromosomes, and each pair of homologous chromosomes may have the same alleles or may have 2 different alleles in each locus. Moreover, allele frequency refers to the proportion of one allele with regard to all alleles at the locus in the population. In this case, there are only two alleles for this locus in the population, and the frequency of the recessive allele is equal to 0,91, thereby the frequency of the remaining dominant allele is equal to 0.09 ( 0.91 + 0.09 = 1).
Huntington's disease is an autosomal dominant trait. Given the pedigree below, if individual IV-4 has three children with a normal woman, what is probability that they would have at least one child with the disorder
Answer:
The answer to the given question is =7/8
Explanation:
In autosomal dominant traits, one copy of the affected gene is enough to cause the disease. Let ’A’ be the affected gene, ‘a’ be the non affected gene. Since IV-4’s parents are a couple of affected and non-affected. So, he has the genes Aa, i.e. a single affected gene.
A a
a aA aa
a aA aa
Number of children affected=[tex]\frac{1}{2}[/tex]
Number child affected out of three = [tex](\frac {1}{2}) ^{3}[/tex]
At least one child affected out of three = 1-P (number of children affected out of 3 )
= [tex]1-(1/2)^{3}[/tex]
= [tex]\frac{7}{8}[/tex]
So, the answer to the given question is 7/8

What is algal bloom?
The rapid increase in production of algae in freshwater and marine water system is called algal bloom. It is also known as the discoloration of water from the algal pigment.What causes algal bloom?
Excessive nitrogen and phosphorus cause overgrowth of algae.The overgrowth of algae consumes oxygen and blocks sunlight from underwater plants. When the algae eventually dies, the oxygen in the water is consumed.As the river and streams are always flowing it will sweep the algae which will prevent it from growing further.

Two different plant species each carry 36 chromosomes (total) in their somatic cells. Species A is diploid, and species B is triploid. What is the haploid (1N) chromosome number for each species
Answer: Species A is diploid, it means 2n=36, the haploid number is 36/2=18. Species B is triploid, it means 3n=36, then the haploid number is 36/3=12.
Explanation:
A chromosome is an ordered bundle of DNA associated with proteins such as histones, and it is found in the nucleus of the cell. Different organisms have different numbers of chromosomes. Humans, for example, have 23 pairs of chromosomes, 22 of them are autosomal pairs, and one pair are sex chromosomes, which indicates the sex of a person. Each parent contributes one chromosome from his or her autosomal pair and one from the sex pair, so that the offspring get half of their chromosomes from their mother and half from their father.
A haploid cell has only one set of chromosomes (n), whereas diploid cells have two sets of chromosomes (2n) and triploid cells have three sets (3n). In the example of humans, a diploid cell is a somatic cell and has 46 chromosomes (or 23 pairs). And a haploid cell, a gamete for example, has 23 chromosomes.
If two species of plants carry 36 chromosomes, and species A is diploid, it means 2n=36. Then the haploid number is 36/2=18. Species B is triploid, it means 3n=36. Then the haploid number is 36/3=12.
g You have made a transgene that expresses green fluorescent protein (GFP) in spermatogonia only. If you are examining a transverse section of the testes where would you expect to find GFP positive (GFP) cells
Answer:
The correct answer is - Associated with the Sertoli cells in the seminiferous tubule.
Explanation:
Interstitial cells are found between seminiferous tubules and Each spermatogonial cell undergoes the process of spermatogenesis process and produces sperms in the lumen of seminiferous tubules.
This could be possible only due to GFP gene expresses only in spermatogonia, we can expect to find GFP + cells associated with the Sertoli cells in the seminiferous tubules.
Therefore, Spermatogonia are associated with Sertoli cells in the seminiferous tubules of the testis.
Whose argument is stronger regarding the SAC curves and the LAC curve? A. The draftsman since the lowest point on each SAC curve will have a horizontal tangent line which only occurs at the lowest point on the LAC. B. Jacob Viner since the SAC curves can be adjusted slightly and still keep their U-shape in a way that makes their lowest points end up on the LAC curve. C. Jacob Viner since the long-run average cost curve must be composed of the lowest points on any individual short-run average cost curve. D. The draftsman since, while it is true that the points of tangency of the SAC curves with the LAC curve are at each SAC curve's minimum, it is impossible to illustrate it accurately.
NB: This is a business question, not biology.
Answer:
SAC (Short-run Average Cost) and LAC (Long-run Average Cost)
The stronger argument regarding the SAC (Short-run Average Cost) curves and the LAC (Long-run Average Cost) curves is:
A. The draftsman since the lowest point on each SAC curve will have a horizontal tangent line which only occurs at the lowest point on the LAC.
Explanation:
The costs of all factors of production become variable in the long run. But in the short-run, some costs are variable, and some are fixed. When the producer starts operating over the long run period, it can then operate without the constraints imposed by the presence of the fixed-cost factors. Therefore, in the long run, the average cost (LAC) is equal to the short-run average cost (SAC) because there is an unconstrained minimum average cost at all output levels.

What are roots of plant?
Roots are organs of higher plants that absorbs water and mineral ions from soil. Two main type of root system is observed in plants: Tap root system and Fibrous root system. Tap root systems are found in dicotyledonous angiosperms (such as pea) and gymnosperms (such as pine) whereas Fibrous root system is mostly observed monocotyledonous angiosperms (such as wheat or rice).
The three main primary function of the roots are:
1. They anchor the plant to the soil.
2. Absorb water and mineral ions from the soil to be later used by the plant.
3. It acts as food reserve.

Thymine in DNA occurs as the result of thymidylate synthase creating _______________ , which then undergoes ____________ to ____________, then to __________, and incorporated into DNA by ___________.
Answer:
The question is incomplete, the complete question is as follow:
Thymine in DNA occurs as the result of thymidylate synthase creating _______, which then undergoes _______ to _______, then to _______, and incorporated into D N A by _______. Thymine in tRNA arises ________, by an S-adenosylmethionine-dependent _______ of a ______ residue in RNA.
Answer:
Thymine in DNA occurs as the result of thymidylate synthase creating dTMP, which then undergoes phosphorylation to dTDP, then to dTTP, and incorporated into DNA by DNA polymerase. Thymine in tRNA arises posttranslationally, by an S-adenosylmethionine-dependent methylation of a UMP residue in RNA.
Explanation:
Thymidylate synthase is a key enzyme that catalyzes the synthesis of 2′-deoxythymidine-5′-monophosphate (dTMP) from 2′-deoxyuridine-5′-monophosphate (dUMP). This enzyme catalyzes the addition of a phosphate group (phosphorylation) of dTMP in order to form thymidine 5'-diphosphate (dTDP). Once synthesized, dTMP can be metabolized to deoxythymidine triphosphate (dTTP), which is a precursor for DNA biosynthesis. On the other hand, transfer ribonucleic acid (tRNA) is methylated after the molecule is synthesized. The transfer of the methyl group is catalyzed by an S-adenosylmethionine–dependent methyltransferase that catalyzes the methylation of uridine monophosphate (UMP) using SAM (S-adenosylmethionine) as the methyl donor.
