Why do only certain cells respond to particular signaling molecules that are sent throughout the body
Answer:
The presence of appropriate receptor dictates which cells will be receptive to a particular signal.
Explanation:
Some cells only respond to certain molecules because they have receptors to accept those molecules. Hence, due to this, only some molecules can be accepted by the cells.
How does a particular cell accept the molecules?Hormones are secreted by endocrine glands into the blood. The endocrine glands, such as the pituitary gland, secrete their hormones directly into the blood, but not all cells of the body can bind to the molecule and perform the cellular functions.
The cells' surface has receptors for molecules such as peptide molecules or polar hormones that can't directly enter the cell. Hence, they bind to the cell surface receptors and send signals with respect to those hormones.
A hydrophobic hormone can directly enter the cell as it can easily pass the plasma membrane. After entering the cell, it has some receptors in the nucleus or in the cytoplasm. This hormone can perform functions such as gene activation after binding with them.
Hence, after binding with receptors, they show their performance, and not every cell has the same receptors for a single molecule.

what are the mechanisms that halophiles typically employ to grow in habitats with high concentrations of salt
Answer:
Synthesis Of Osmoprotectants
Explanation:
One Mechanism Halophiles use to survive in high concentrations of salt is the Synthesis Of Osmoprotectants, which are also known as compatible solutes. These work by balancing the internal osmotic pressure with the external osmotic pressure, making the two solutions isotonic, or close to it.

Answer: Respiratory pump
Explanation:
By breathing deeply, the mechanism that Archie did hessist to return venous blood to his heart.
During the process of inspiration and expiration when the muscles contract and relax, pressure changes takes place in both the thoracic and abdominal cavities and this changes compress the nearby veins and help im the return of blood to the heart.
Determine which of the following statements is true about energy in ecosystems A. Consumers pass on 20% of the energy they get from a lower trophic level. OB. Primary consumers lose 60% of the energy they absorb from producers as urine and feces. C. 10% of the energy Primary consumers absorb is lost as heat. Ons Primary producers lose 20% of the energy they absorb as urine and feces.
Answer: C. 10% of the energy Primary consumers absorb is lost as heat.
Explanation:
According to the ten percent law of energy flow only 10 percent energy is transferred from one trophic level to the next trophic level and rest of the energy is used to develop the biomass and lost as heat. As the loss of heat is an essential exothermic reaction after the digestion and assimilation of food the energy is lost as heat from the body of the primary consumers is 10%. Primary consumers are animals that are dependent on plants for their food requirements for example deer, goat and others.

Flat bones have surfaces composed of ______ bone with internally placed ______ bone. Multiple choice question. compact, spongy
Answer: compact, spongy
Explanation:
Flat bones have surfaces composed of (compact) bone with internally placed (spongy) bone.
Flat bones are typically thin, although they're often curved. Some examples of flat bones are the cranial in the skull, scapulae which is known as the shoulder blades, ribs, and sternum. They're an attachment for muscles and are used in the protection of internal organs.

When individuals migrate, alleles can be transfered from one population to another population. This commonly referred to as
Answer:
Gene flow.
Explanation:
When individuals migrate, alleles can be transferred from one population to another population which is known as gene flow. Gene flow is also called gene migration, the introduction of genetic material through interbreeding from one population of organisms to another which changes the composition of the gene pool of the migrated population of organisms. This gene flow creates a new species that is different from previous population of organisms
Recently discovered genetic evidence shows that multicellular land plants such as corn and wheat, are all of one lineage – they all arose from a single type of algae. Fossil evidence suggests that other types of algae did not have the needed complexity to move into terrestrial ecosystems. Explain at least 3 adaptations that algae would need to be able to survive on land.
Answer:
1) they would need a host or vessel to stay on and feed of of their body
2) they would need some for of reproduction in the host ( mitosis whatever the algae my use )
3) they would need to wisely choose there hosts and of what they feed on so there host doesn’t die quickly
I don’t know if this is what your looking for but these are 3 things that algae would need to live
Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, would you expect the pH of the intermembrane space to increase or decrease
Answer:
Increases.
Explanation:
The pH of the intermembrane space increases as the poisoning of cyanide occurs. After cyanide poisoning, the electron transport chain can stop pumping of electrons into the intermembrane space. The pH of the intermembrane space would increase, the pH gradient would also decreases, and ATP synthesis would stop to occur. The pH of the intermembrane space is neutral i.e. 7 but due to cyanide it move towards basic.
Answer:
Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, the pH of the intermembrane space becomes more basic. The electron transport chain can no longer pump hydrogen ions into the intermembrane space and ATP synthesis stops.
Which of the following adaptations enables deciduous trees to produce more food?
a.
broad leaves
b.
thick bark
c.
leaf loss
d.
color change
The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food. Broad leaves have the benefit of increasing the photosynthetic rate, resulting in more food production.
What is the role of the leaves?Leaves are of many types, such as the neddle-shaped leaf and flat leaves, and all these leaves are adapted to different climatic conditions. The plants that are present in the tropical area have comparatively flat leaves compared to those that are present in the cold areas in order to control transpiration and heat.
Leafy plants that are green in color have chloroplasts and chlorophyll pigments that help in the photosynthesis process. Because the photosynthesis process produces food, if the leaf is green, it has more chloroplasts and thus produces more food.
Hence, The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food.

Why is it that although Nocardia spp. grow well on most common nonselective laboratory media, many are missed when the cultures are read
Answer:
These organisms require 3 to 6 days to grow.
Explanation:
Nocardia are a group of actinomycetes. Some of the species of the nocardia are pathogenic to the humans. There are more than 70 species of nocardia in the world.
Some of the Nocardia spp. grow on the most common non laboratory media but many of them are missed out when the cultures are read because these organisms requires at least 3 days to 6 days to grow.
A diagram shows a potato producing new tubers. Buds on the parent plant grow into stems that grow downwards called stolons. The end of each stolon develop in to new tuber.
1) Give two pieces of evidence which show that this is an asexual method of reproduction.
2) Explain why all the new tubers will be genetically identical.
Answer:
See the answer below
Explanation:
Evidence that shows that the illustration is an asexual method of reproduction:
1. New tubers were produced without any signs of flowering or fertilization
2. Parent plant was produced from a vegetative part ( a tuber).
All the new tubers would be genetically identical because they were produced without fertilization. They all developed from the division of some of the vegetative cells (mitosis) of the parent plant. Hence, they are not only genetically identical with themselves but also with the old tuber that produced the parent plant.

Answer:
The answer is "supported and when fruit was removed"
Explanation:
It dated the idea from this laboratory because the distribution of avian beaks differed. If any kind of food available keeps shifting, the frequency of the beak types changes as beaks with beaks is far more suitable for food available. The data in this laboratory confirmed the theory, so because the fruit was removed by birds. These results of this laboratory confirm this idea because the dispersion of pigeons when food was taken was varied.
