Answer:

d. Pluripotency markers  

Explanation:

Pluripotency can be defined as the capacity of individual cells to differentiate into any cell type. Pluripotent transcription factors are pluripotent proteins that promote the differentiation of embryonic stem cells (ESCs) into stem/progenitor cells by inducing the expression of target genes, which are also capable of maintaining their pluripotent state. For example, SOX2, OCT4 and NANOG are pluripotent transcription factors highly expressed in ESCs in order to maintain the pluripotent state of these cells.

Explanation:

The correct answer is B. If there was an increase in nest sites, the pigeon population would increase. This would of course be due to the greater amount of space in which the pigeons could breed and raise their offspring.

So answer is B

Answer:

In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products. Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture.

Explanation:

Threshing- The process of separating grains from the harvested crop is called threshing.

Explanation:

Answer:

D

Explanation:

The statement provides the strongest explanation for the trends in the two populations is predator-prey relationships act as density-dependent limiting factors on both predators and prey. Hence option D is correct.

Predator is defined as an organism that mostly hunts and consumes other organisms for food. The term "predator" refers to a species that hunts and eats specific other organisms. The animals that predators consume are referred to as prey.

Predator-prey interactions and prey-predator interactions are both crucial density-dependent population controls. The other population's size determines how each population changes in size.   When the population density reaches a particular point, a density-dependent limiting factor takes effect. Competition, parasitism, and disease are other instances of density-dependent limiting variables.

Thus, the statement provides the strongest explanation for the trends in the two populations is predator-prey relationships act as density-dependent limiting factors on both predators and prey. Hence option D is correct.

Answer:

Explanation:

The observable traits expressed by an organism are referred to as its phenotype. An organism's underlying genetic makeup, consisting of both physically visible and non-expressed alleles, is called its genotype.

Answer:

190 ATP molecules

Explanation:

Cellular respiration is the process whereby energy (ATP) is obtained in the cells of living organisms by breaking down glucose molecules. Cellular respiration can either be aerobic or anaerobic depending on whether oxygen is present or not.

In the presence of oxygen, aerobic respiration, which consists of three stages namely: glycolysis, Krebs cycle and oxidative phosphorylation, is employed. Per glucose molecule;

- Glycolysis produces 2 ATP molecules,

- Krebs cycle produces 2 ATP molecules

- Oxidative phosphorylation produces 34 ATP molecules

Hence, in total, 38 ATP molecules is produced per glucose molecule in aerobic respiration. According to the question, 5 molecules of glucose will yield 5 × 38 = 190 molecules of ATP.

Answer:

1. Homeostasis

2. Organ system

3.The bones of the skeletal system serve to protect the body's organs, support the weight of the body, and give the body shape. The muscles of the muscular system attach to these bones, pulling on them to allow for movement of the body.

4.The nervous and endocrine systems are two forms of communication system in the human body that integrate, coordinate and respond to sensory information which is received by the human body from its surroundings

5.The skin functions by protecting the body from basic elements of nature such as water, UV sunlight and wind. ... However, skin in integumentary system acts by maintaining the internal conditions that is required by the body while it is excretory system because it secretes a fluid waste called sweat or perspiration.

6.In order to survive, cells must satisfy some basic needs such as oxygen, water, nutrients, waste removal, and maintaining of homeostasis. Oxygen and nutrients are necessary for different processes inside the cell. For instance, cellular respiration uses glucose and oxygen to form energy in the form of ATP.Water is important for different chemical reactions, as well. Also, the result of different processes, waste is produced and it is important to remove it from the cell. Finally, it is important that cell and whole body conditions do not vary so much and that homeostasis is maintained.

7.Ribosomes provide another good example of structure determining function. These small cellular components are made of protein and ribosomal RNA (rRNA). Their main function is to translate messenger RNA, or mRNA, into strings of amino acids called proteins.

8.  the body is not in homeostasis from 7 to 10 hours. Explanation: The given graph shows homeostasis in terms of body temperature. The normal body temperature, that is 37 degrees C is maintained from 1 to around 6:45 hours.

9.There are several reasons why the body temperature falls continuously just like when you are exposed to an extreme cold weather or wearing wet clothing for a long time. This abnormality state of the body temperature can lead into some potential diseases and disorders like infection, insomnia, stress and sepsis

10.Sweating also hydrates your skin and maintains the balance of electrolytes in your body. The fluid you sweat comprises mainly salt and water. Excessive sweating can cause dehydration since you lose a large amount of water. The technical term for excessive sweating is hyperhidrosis.

The following that are functions of the exoskeleton are:

An exoskeleton is an outer skeleton that is present outside the body of some insects and other organisms. The exoskeleton is made up of hard substances like calcium carbonate or chitin protein.

The exoskeleton protects the soft tissues and organs of organisms. They are helpful in saving the organism from predators and other factors of the environment.

The exoskeleton is present in most arthropods. They also help in reducing water loss from the body.

Thus, the functions of the exoskeleton are:

Because Earth has limited materials and room for deceased creatures, biogeochemical cycles are vital to life and ecosystems. Biogeochemical cycles transport and store these chemicals for living creatures.

Because there is a finite quantity of stuff on earth and a certain amount of room for dead species as well, biogeochemical cycles are crucial for life and significant to ecosystems. Additionally, biogeochemical cycles are crucial because they move and store these chemicals so that living things may use them.

The flow of nutrients and other elements between biotic and abiotic forces is referred to as "biogeochemical cycles" in most cases. The words "bio" and "geo," which refer to the biosphere, "geo" and "chemical," which refer to the elements that flow through a cycle, are the roots of the phrase "biogeochemical."
