Which of the following best describes what happens to water molecules after they are released from plants through transpiration?
a. They will combine to form runoff and flow into rivers, lakes, and oceans.
b. They will cool and form dew, clouds, or fog through condensation.
c. They will fall to Earth in the form of rain, sleet, or snow.
d. They will undergo evaporation and change to a gas. ...?
Answer: d. They will undergo evaporation and change to a gas. ...?
Transpiration is a process of loss of excess water from the small pores present on underside of leaves. The water released by this process evaporates and converted into water vapor (gas). The water vapors formed by this process are released in the atmosphere. The rate of transpiration depends upon weather conditions, such as humidity, sunlight, temperature, and wind.
Dolly was a female domestic sheep, and the first mammal to be cloned from an adult somatic cell, using the process of __________________.
A) DNA transfer
B) cell transfer
C) oocyte transfer
D) nuclear transfer
Answer: The correct answer for the blank is-
D) nuclear transfer.
Dolly was a female domestic sheep, and the first mammal that was cloned using an adult somatic cell ( particularly a mammary gland cell from a Finn Dorsett sheep). She was produced using a technique, which is termed as somatic cell nuclear transfer.
In this technique, the nucleus from an adult somatic cell was transferred to an unfertilized oocyte ( which was first enucleated that is nucleus was removed). After this, unfertlized egg was activated using electrical stimuli, which initiated cell division and produced Dolly.
Thus, option D) nuclear transfer is the right answer.
What two components are often found as part of an enzyme?
Answer:
The correct answer is - Protein (the apoenzyme) and active site (cofactor).
Explanation:
The two components which often present as the part of an enzyme are active site and protein. The part which is protein consists of one or more than one chain of the amino acids that form macromolecules. They perform an essential function within an individual organism.
An active site is the part of an enzyme that binds with the substrate molecule and initiates the enzyme reaction by regulating the chemical reaction.
Thus, the correct answer is - Protein (the apoenzyme) and active site (cofactor).
Because there is more oxygen in an alveolus (sac in the lung) than in the blood around it, oxygen diffuses
Answer:
When there is more oxygen in alveolar sac than in blood capillaries, oxygen will diffuse from alveolar sac to blood capillaries.
Explanation:
The concept behind this is very simple. Oxygen or carbon dioxide move according to their partial pressure differences at various places. Gases always move from an area of high partial pressure to an area of low partial pressure. Pulmonary artery carries the deoxygenated blood from heart to lungs. Near the alveoli of lungs exchange of gases take place. Oxygen from the inhaled air enters into the blood capillaries and carbon dioxide from the blood capillaries move into the alveolar sac for exhalation.
Where do the light-independent reactions of photosynthesis take place?

Which RNA base pairs with the adenine In DNA
Answer:
The correct answer is uracil.
Explanation:
The associations between the nucleobases take place via the complementarity of nucleobases. In the DNA, the base complements are adenine-thymine and guanine-cytosine. In the RNA, the base complements are adenine-uracil and guanine-cytosine. Thus, only DNA comprises thymine, while in RNA uracil is found in place of thymine.
RNA is a kind of nucleic acid, which performs an essential function in the flow of information from the DNA to the proteins. For the expression of the gene, information has to be conducted via RNA. Each nucleotide in RNA comprises a ribose sugar, a nitrogenous base, and a phosphate group. The nitrogenous bases in RNA comprise guanine, adenine, uracil, and cytosine, that is, thymine gets substituted with uracil.
It is impossible to____ and talk at the same time.A. listen, B. breathe, C. hear. Hearing is when the sound reaches your ears. Listening, however, when it reaches your brain.Hearing is when the sound reaches your ears. Listening, however, when it reaches your brain
The correct answer is option A
Listening is the ability of the brain to understand and react to the words. both the ears and brain is involved in the action of listening.
But hearing only involves the ears not the brain.
While we are talking to somebody we can easily hear all the things that is said but when it comes to listening we need to stay focused as it involves brain.
So, it is impossible to listen while we are talking.

Explanation:
Both cellular respiration and the burning of fossils fuels release energy. This can be attributed to
A)
the breaking of bonds during oxidation.
B)
the reduction of carbon to carbon dioxide.
C)
the formation of bonds in new organic compounds.
Eliminate
D)
the hydrolysis of water molecules into oxygen and hydrogen.
The answer is
A) the breaking of bonds during oxidation.
Fossil fuel is a hydrocarbon which contains carbon and hydrogen and when it is burnt the carbon forms carbon dioxide and the hydrogen forms water. For both these processes the fuel uses free oxygen from the air. In both cases the formation of the Carbon-Oxygen and Hydrogen-Oxygen chemical bonds produces energy in the form of heat.

what can happen to the soil after the mice have destroyed the roots of the grass?
Because of their physical capabilities, mice can cause significant damage. They are ultimate climbers and swimmers. Mice lives in grassy or bushy habitats, where they nest underground in shallow burrows or aboveground in densely vegetated area. They damage the roots of plants that leads to their destruction.
What are the methods to control mice?Mice gnaw and severely damage the bark and roots of young trees. Biting into ripening tomatoes, cucumbers, beans, peas, and other fruit close to the ground.
By digging tunnels, they continuously mix waste and food stores with the soil. The nutrients from the food they eat are thus quickly returned to the soil.
Thus, in this way mice affect the soil leading to destruction of roots.

can you help me Create an analogy describing how 3-4 components of the endocrine system communicate with each other and function effectively.
The endocrine system has many glands that interact with each other through feedback mechanisms to ensure that the correct amounts of hormones are produced at the right time.
How does the endocrine system work?Numerous hormones control a variety of bodily processes, including electrolyte balance, growth and development, metabolism, and reproduction. The body's many glands all create hormones. A variety of releasing and inhibiting hormones from the brain work on the pituitary gland to promote the production of pituitary hormones.While some pituitary hormones have an indirect effect on target organs, others act on other glands spread across the body. The adrenal glands, which predominantly create cortisol, the parathyroid gland, which produces parathyroid hormone, and the pancreas, which produces insulin and glucagon, are additional hormone-producing glands found throughout the body. Many of these hormones are components of regulatory hormonal cascades that also include hormones from the hypothalamus, the pituitary, and one or more target glands.The feedback mechanisms among various endocrine glands act in a loop and ensure the smooth functions of the endocrine system.

a virus is unlike an organism in that the virus is __________.
A virus is unlike an organism in that the virus is not considered a living organism.
Unlike organisms, viruses lack the essential characteristics of life, such as the ability to grow, reproduce independently, and carry out metabolic processes.
Instead, viruses are obligate intracellular parasites that require a host cell to replicate and carry out their life cycle. They consist of genetic material (DNA or RNA) enclosed in a protein coat but lack cellular structures or machinery.
Viruses cannot perform vital life functions on their own and are inert outside a host cell.
Their replication involves hijacking the host cell's machinery to produce new viral particles, highlighting their distinct nature from living organisms.
