Answer:
Recapitulation Theory.
Explanation:
The growth of embryos in the womb of the female that repeats its evolutionary family history is known as Recapitulation Theory. Recapitulation Theory refers to the theory which states that the stages an organism passes through during its embryonic development will repeat its evolutionary stages of change of structural in its ancestral lineage. The development of embryo passes through or repeat the same stages from which its ancestors passes through.

Animals that have analogous structures probably (choose 2)
A. evolved from the same common ancestor
B. are headed for extinction
C. are not related
D. evolved in the same environment
(I WILL GIVE BRAINLIEST)
Answer:
Explanation: For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying. The presence of the analogous structure, in this case the wing, does not reflect evolutionary closeness among the organisms that possess it.
Ribosomes are tiny factories within cells that do all of the following EXCEPT
A. decode an mRNA message into a protein
B. assemble amino acids into polypeptide chains
C.attach to mRNA molecules in the cytoplasm
D. translate DNA into RNA
Answer:
d. translate DNA into RNA
Explanation:
An RNA polymerase binds to promoters and then breaks down hydrogen bonds between two strands of the DNA and attaches on one of them. A DNA strand is used as a template for a new RNA molecule. In this way, pre-mRNA is made, which becomes mRNA after the introns are removed.
A mRNA molecule enters the ribosomes, located in the cytoplasm. In these organelles, a transfer RNA attaches to a mRNA and the process of translation begins. The final product is a polypeptide chain.
The Ribosomes should be considered for small factories within cells that does not involved the translate DNA into RNA
What is RNA?The polymerase binded for promoters and then split down hydrogen bonds that lies between 2 strands of the DNA and then attached one of them.
The DNA strand should be used like the template for the new RNA molecule. Also, the mRNA should be made that becomes mRNA when introns should be removed.

difference between plant and animal tissues give me 6 points in tabular form
Explanation:
Cells in plant tissue have a cell wall. Animal tissue cells do not have a cell wall. ... They are four types of muscle tissue, epithelial tissue, nerve tissue and connective tissue. These tissues require less energy and maintenance because the plants do not need movement.
A researcher claims that budding yeast are able to survive in different environments because they produce enzymes that allow them to use different molecules as sources of matter and energy.
Which of the following statements best helps justify the researcher’s claim by providing a relevant example?
A. Yeast cells produce protein kinases, which are enzymes that catalyze the transfer of phosphate groups from ATP to protein substrates.
B. Yeast cells produce DNA polymerases, which are enzymes that catalyze the conversion of free nucleotides into strands of DNA.
C. Yeast cells produce invertase, which is an enzyme that catalyzes the conversion of the disaccharide sucrose into glucose and fructose.
D.Yeast cells produce catalase, which is an enzyme that catalyzes the conversion of hydrogen peroxide into water and oxygen gas.
Answer:
The correct answer is - C. Yeast cells produce invertase, which is an enzyme that catalyzes the conversion of the disaccharide sucrose into glucose and fructose.
Explanation:
Invertase is an enzyme that hydrolyses the sugar molecule which is sucrose in this condition by performing an inversion of optical rotation which gives it invertase term. Extracellular invertase in budding yeast leads to the hydrolysis of sucrose and yield glucose.
Glucose acts as a source of energy and matter in this process at the end so the budding yeast produces an enzyme invertase that allows it to survive in different conditions.
The statement which best helps justify the researcher’s claim by providing a relevant example about budding yeast is: C. Yeast cells produce invertase, which is an enzyme that catalyzes the conversion of the disaccharide sucrose into glucose and fructose.
A yeast can be defined as an eukaryotic, unicellular (single-celled) microscopic fungus that typical reproduces through budding.
Basically, a yeast is a member of the fungus kingdom and it comprises single oval cells.
Also, this microscopic fungus produce enzymes (invertase) that allow them to convert sugar (disaccharide sucrose) into alcohol and carbon dioxide.
In conclusion, budding yeasts can survive in different environments because they produce enzymes (invertase), which catalyzes the conversion of disaccharide sucrose into the following chemical substances:

Potatoes can be genetically modified so that they are _________ to plant-eating beetle?
A. Toxic
B. Tacky
C. Tasty
D. None of these
Answer:
A or D
Explanation:
You would want to genetically modify the plant so that the beetles wouldn't want to eat it. If it is toxic, the bugs would stay away from it. However, you could also just modify the plant so that it doesn't taste good for the bugs, in which case you should pick D. Choose whichever answer you think is best.

Answer:
People born first or last in a family have a different perspective than people born in the middle. Research has indicated that firstborn children are more likely to be achievement-oriented and responsible than later-born children. Later-born children on the other hand, tend to be better in social relationships and to be more affectionate and friendly. Other studies suggest that first-borns are conservative in their thinking and are defenders of the status quo. Later-borns, in contrast, are often risk-takers and social and educational rebels.

A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine.
Does fungi have a cell wall
Answer:
Unlike plant cells, fungal cells do not have chloroplasts or chlorophyll. ... The rigid layers of fungal cell walls contain complex polysaccharides called chitin and glucans. Chitin, also found in the exoskeleton of insects, gives structural strength to the cell walls of fungi.

Do you feel stem cell research is important? Explain.
4 sentences.
Given their unique regenerative abilities, stem cells offer new potentials for treating diseases such as diabetes, and heart disease. Research on stem cells continues to advance knowledge about how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms.
Yes. Without stem cell research there would be alot more sick people. There would be alot more sick people because Stem-cell research is an area of research that studies the properties of stem cells and their potential use in medicine. As stem cells are the source of all tissues, understanding their properties helps in our understanding of the healthy and diseased body's developmental and homeostasis. Stem cells originate from two main sources: adult body tissues and embryos.
