What can affect the death rate of mouse population and explain why
The death rate of the mouse population is significantly affected by the overpopulation of its predators like cats, owls, snakes, etc.
What do you mean by Population?The Population may be defined as a group of individuals belonging to the same species living in the same area at a given time period of time.
According to the context of this question, if the number of predators of the mouse population is higher than that of the mouse, the death rate is generally found to be higher.
While if the population of the predator is low, as compared to the mouse, then the death rate is probably less. Other factors like space, food, mating partners, etc. may also describe the death rate of any species.
Therefore, the death rate of the mouse population is significantly affected by the overpopulation of its predators like cats, owls, snakes, etc.

How does the electron transport chain deal with the electrons removed from sugar molecules?
Answer:
Explanation:
The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor of the electrons removed from the intermediate compounds in glucose catabolism. The electron transport chain is composed of four large, multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.
The electrons passing through the electron transport chain gradually lose energy, High-energy electrons donated to the chain by either NADH or FADH2 complete the chain, as low-energy electrons reduce oxygen molecules and form water.
These same molecules can serve as energy sources for the glucose pathways.

Which of these processes does not occur as part of the cell cycle in animal cells?
1) Mitochondrial DNA is released into the cytoplasm
2) Two identical copies of chromosomes are produced
3) Cell growth and mRNA synthesis occur
4) Nuclear DNA is replicated
The cell cycle is an essential process of growth and function. It has many phases which divide the genetic material and the cytoplasmic organelle equally into new cells. The cell cycle is crucial for survival.
Option 1) Mitochondrial DNA released into the cytoplasm is the process that does not occur in the animal cell cycle.
Cell cycle steps in animals can be explained as:In the animal cell cycle during the synthesis step, the genetic material replicates to produce two identical chromosomal groups.The cell divides to grow and the processes of central dogma including mRNA synthesis and protein formation occur.Mitochondrial DNA does not get released in the cytoplasm but remains sustained in the mitochondria structure.Therefore, mitochondrial DNA is not discharged into the cytoplasm.

CONSIDERAS QUE ES CORRECTO DECIR QUE LOS ANTIBIOTICOS SON MALOS PARA LAS BACTERIAS? Argumenta tu respuesta
Answer:
Sí, ya que su función es matarlas o impedir que aumente el número de estas.
Explanation:
Los antibióticos actúan sobre las bacterias ya sea matandolas o evitando que la población de un determinado tipo de bacterias se reproduzca haciendo que los mecanismos de defensas presentes en nuestro cuerpo puedan actuar sobre las bacterias ya existentes.
Los antibióticos pueden ser específicos para cierto tipo de bacterias o actuar de forma general afectando a varios tipos de bacterias presentes en nuestro organismo. Si se atacan bacterias que están normalmente en nuestro cuerpo por acción indiscriminada del antibiótico, nuestro organismo sufre un desequilibrio ya que las bacterias que tendrían que estar presentes para procesar ciertos elementos o realizar otras funciones no están.

What is the process that the tree uses to get its energy called?Does this process directly or indirectly affect the energy needs of animals such as the ostrich?
Photosynthesis is the process by which trees and all other flora (plants) get energy. And I think that it directly helps animals, such as ostriches, by providing food and O2 (oxygen). Without oxygen, humans and animals couldn't survive because there is too much CO2 (carbon dioxide) in the air (humans get this thing called carbon dioxide poisoning, which can kill you eventually). Also, without food, we would all starve to death.
Hope this helps! :)
Plants use a process called photosynthesis to transform solar energy into their own energy.
What is photosynthesis?Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.
Solar or radiant energy is converted into chemical energy during photosynthesis. The rate of photosynthesis has a direct impact on the productivity of agricultural crops.
It gives the atmosphere the oxygen that all living things need. It keeps the ecosystem's oxygen and carbon dioxide levels in check.
The process by which leaves take in carbon dioxide and water and use the power of the sun to transform them into chemical compounds like sugars that feed the tree is known as photosynthesis.
Thus, through the process of photosynthesis, tree uses to get its energy.

Name the 6 roles of proteins in the body.
Answer: 1. Repair and Maintenance
Protein is termed the building block of the body. It is called this because protein is vital in the maintenance of body tissue, including development and repair. Hair, skin, eyes, muscles and organs are all made from protein.
2. Energy
Protein is a major source of energy. If you consume more protein than you need for body tissue maintenance and other necessary functions, your body will use it for energy. If it is not needed due to sufficient intake of other energy sources such as carbohydrates, the protein will be used to create fat and becomes part of fat cells.
3. Hormones
Protein is involved in the creation of some hormones. These substances help control body functions that involve the interaction of several organs. Insulin, a small protein, is an example of a hormone that regulates blood sugar. It involves the interaction of organs such as the pancreas and the liver. Secretin, is another example of a protein hormone. This substance assists in the digestive process by stimulating the pancreas and the intestine to create necessary digestive juices.
4. Enzymes
Enzymes are proteins that increase the rate of chemical reactions in the body. In fact, most of the necessary chemical reactions in the body would not efficiently proceed without enzymes. For example, one type of enzyme functions as an aid in digesting large protein, carbohydrate and fat molecules into smaller molecules, while another assists in the creation of DNA.
5. Transportation and Storage of Molecules
Protein is a major element in transportation of certain molecules. For example, hemoglobin is a protein that transports oxygen throughout the body. Protein is also sometimes used to store certain molecules. Ferritin is an example of a protein that combines with iron for storage in the liver.
6. Antibodies
Protein forms antibodies that help prevent infection, illness and disease. These proteins identify and assist in destroying antigens such as bacteria and viruses. They often work in conjunction with the other immune system cells. For example, these antibodies identify and then surround antigens in order to keep them contained until they can be destroyed by white blood cells.
