Three stages of development from an embryo from a fish salamander turtle and chicken . What information about evolutionary relationships can be inherited from the drawings
Answers
Answer:
Zygote, cleavage and hatching are embryogenic stages of fish, salamander, turtle and chicken.
Explanation:
The main embryogenic development stages of fish, salamander, turtle and chicken were zygote, cleavage and hatching. all these stages are present in these organisms which shows that fish, salamander, turtle and chicken are evolved from a single ancestor. Due to similar embryogenic development stages indicates close evolutionary relationships among these organisms.

Describe the nitrogen cycle. How do organisms obtain nitrogen? (minimum 5 sentences) ILL GIVE BRAINLIEST
Answers
Answer: Plants, from their roots, suck up nitrogen compounds. These compounds are obtained by animals as they consume plants. The nitrogen compounds in the organic matter re-enter the soil when plants and animals die or when animals excrete waste, where they are broken down by microorganisms, called decomposers.

Describe the main molecule found in nucleus and explain how it controls the cells functioning
Answers
The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.

Wheat has flowers similar to those in Fig. 5.1, but reproduces by self-pollination. Explain the consequences of self-pollination for a population of plants.
Answers
Answer:
The transfer of mature pollen grain from anther of the flower to the stigma of the same flower of the same [species is called self pollination.
Generally, the transfer of pollen grains by wind,animals,and water to stigmas is called pollination. It is a means of vegetative propagation which ensures reproduction.
Therefore during self pollination, the same genes are distributed from one generation to another. Thus genetic purity is ensured. It also ensured reproductive success. because there is little chance of the pollen grain getting lost in transit. It is also certain a particular plant would always breed true.
Additionally it prevent the process of transfer of genes in some transgenic crops( rice, maize) where through genetic engineering some genes are introduced in their genome.
The only negative effect is lack of genetic diversity. Therefore after a period of time the plants get weak and prone to diseases and infection. Because of poor resistant from lack of variation.

Gravity has a strong pull and when rocks aren't in a good position/stable position they start to fall.
Gravitational Erosion

When chunks of stone fall from a mountainside to the ground below, it is because gravity pulled it down. When a glacier moves through a mountain range, slowly flattening or carving the earths surface in that area, it is because the pull of gravity forces the glacier downhill.

Can you think of any organism that make their own food but also eat other organism or their byproducts to survive?
Answers
Answer:
Heterotrophs, also known as other-feeders, can't capture light or chemical energy to make their own food out of carbon dioxide. Humans are heterotrophs. Instead, heterotrophs get organic molecules by eating other organisms or their byproducts. Animals, fungi, and many bacteria are heterotrophs.

When comparing animal to plant cells, they are different in size, shape, and how they store energy. They have similarities, as well. Which organelles perform similar functions in both plant and animal cells. Group of answer choices D. Ribosome, cell membrane, chloroplast C. Cell membrane, cell wall, nucleus
Answers
Answer:
ribosome, cell membrane, nucleus
Explanation:
The organelles that perform similar functions in both plant and animal cells among the listed organelles would be the ribosome, the cell membrane, and the nucleus.
First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.
The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.

Decomposition is the process by which:
Carbon atoms are released into the soil
Carbon is converted to CO2
Organisms obtain energy by breaking down glucose
Answers
Answer:
Decomposition is the process by which carbon atoms are released into the soil.
Explanation:
Organic decomposition involves the process of degradation of a living organism by releasing its elemental components.
In the process of decomposition, chemical elements such as carbon are released mainly in the soil, contributing to its enrichment and use by other living beings.
The release of carbon —product of decomposition— to the soil, for recycling, is part of the carbon cycle.
The other options are not correct because:
The conversion of carbon into CO₂ is combustion. Organisms obtain energy by breaking down glucose is part of cellular respiration.HgO2 → Hg + O4

How do police use DNA to try and solve crimes? Do you think city police departments should make their own DNA databases? Explain why or why not. Back up your answer with facts and details from the Article.
Answers
Answer:
Police matches the DNA with the criminal present in their database.
Explanation:
Police use DNA that are collected at the site of crime in order to solve crimes because the criminals DNA are mostly found at the site of crime. the police collected these DNA and search in their database where the DNA of all the criminals are present. if the DNA matches with the criminal present at the database so it means that this criminal commit this crime so it is arrested and further investigation will be held. Yes, city police departments should make their own DNA databases in order to solve the case quickly.
