Plants, like all organisms, adapt to the conditions of their environment. Some special challenges a plant may face are drought, flooding, and a salty environment. Your task is to identify and describe ways that plants adapt to these challenging conditions in their environment. Select one plant adaptation to drought, one adaptation to flooding, and one for salt tolerance. Explain how each adaptation enhances plant survival. Identify a scholarly source of information for each
Answer:
Hydrophytes is flood tolerant plants, barley is salt tolerant crop and sorghum is a drought tolerant crop.
Explanation:
Hydrophytes also known as flood tolerant plants that have adaptations to survive flood problems. The plant has the development of air spaces in the roots and stems which allow diffusion of oxygen from the aerial portions of the plant into the roots. Barley shows a greater degree of salt tolerance by applying method of osmoregulation which helps the plant to tolerate salt stress. Sorghum is a plant that is adapted to drought condition. These plants have less number of stomata and waxy layers on the leaves which lowers the rate of evaporation or transpiration.

Blackcap birds (Sylvia atricapilla) migrate out of Germany before wintertime. Prior to the 1960s, all members of a particular blackcap population flew to Spain, which had an abundant natural food source. Now, some members of the same blackcap population fly to the United Kingdom, where food placed in feeders by humans is abundant. The blackcaps return to the same forests in Germany to nest during the breeding season.
Some blackcaps that migrate to the United Kingdom have become distinguishable by certain physical and behavioral traits from blackcaps that migrate to Spain. Which of the following best predicts the effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter?
A- The blackcaps that migrate to Spain will selectively mate with the blackcaps that migrate to the United Kingdom, resulting in increased genetic variation in the blackcap population.
B- The blackcaps that migrate to the United Kingdom will become reproductively isolated from the blackcaps that migrate to Spain, resulting in speciation in the blackcap population.
C- The blackcaps in Spain and the United Kingdom will migrate to other geographical locations in search of potential mating partners, resulting in a smaller blackcap population in Germany.
D- The blackcaps will begin nesting at their wintering sites in Spain or the United Kingdom, resulting in a larger blackcap population migrating back to Germany after the breeding season has ended.
Answer:
D- The blackcaps will begin nesting at their wintering sites in Spain or the United Kingdom, resulting in a larger blackcap population migrating back to Germany after the breeding season has ended.
Explanation:
By the inhabitants of Spain and the United Kingdom placing feeders out for the blackcaps, the birds in their nesting sites during the winter will have food to eat, meaning a bigger population of the Blackcaps when they return to their main home in Germany.
This best predicts the effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter.
A population of deer lives in Canada. Over 50 years, the size of the deer
population decreased. What best explains the decrease in the size of the deer
population?
Answer:hunting
Explanation: They can lose population .
Fewer deer were born than died best explains the decrease in the size of the deer population.
What is population?In particular geographical area, when group organism of same particular species inhibit, and they are capable of interbreeding, refers to as population.
This field is important in conservation biology, especially in the development of population survival analyzes that let us predict the long-term likeliness of species remaining in particular habitat parts. Population ecology Although it is a branch of biology, it presents interesting problems for mathematicians and statisticians studying population dynamics.
So, when population size of deer decreased over 50 years, we can say that deer populations are declining due to death, animals leaving the area or dispersal (migration).
Population change = (births + immigration) - (deaths + immigration).

Proteins on the surface of vesicles determine where the vesicles go. Which cell organelle provides the instructions for these proteins?
OA. endoplasmic reticulum
OB. lysosome
Ос. mitochondria
OD
nucleus
Answer:
D. Nucleus.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Some examples of cell organelles found in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.
Proteins on the surface of vesicles determine where the vesicles go.
The nucleus is the cell organelle which provides the instructions for these proteins. It controls all the activities taking place in the cell and the synthesis of proteins.

Answer:
Hibernation helps animals survive the changing seasons. Foods that bears eat, such as berries and flowers, are much less available during cold winter months. When they hibernate, bears enter a deep sleep. ... While they sleep, the bears can survive because their bodies live off of their stored fat or food.
During hibernation, the animal’s body temperature, heart rate and breathing rate all drop to significantly lower levels. Animals do this to survive the winter because the weather is cold and food is scarce. It is advantageous because these animals can quite literally shut themselves off for weeks at a time rather than try and survive through harsh weather conditions.
While many people think bears are hibernators, they actually participate in a similar, though not exact, practice. Instead of hibernating, bears fall into a deep sleep called torpor. During torpor, heart rate and breathing rate decreases, body temperature reduces slightly and bears do not eat or release bodily waste. Bears can sleep more than 100 days without eating, drinking, or passing waste!
Bears sleep in dens that they make themselves, as well as in hollow trees, caves and dens built by other bears. A den can be built in 3–7 days, however, the timing of den building varies from bear to bear. While some bears build their dens months before hibernation season, others choose to excavate their dens.
These animals can dramatically drop their body temperature to below freezing—salty body fluids work to prevent tissue crystallization in particularly cold temperatures.
So really, animals that are true hibernators don’t actually sleep through the entire winter.
The urea produced by their fat metabolism is broken down and the nitrogen is re-used by the bear to rebuild protein.

How would this diagram be
different if it showed anaphase I of meiosis instead of anaphase of mitosis?
A Each chromosome would still have two chromatids.
B The chromosomes would look the same as in mitosis.
C You would be able to see DNA in the chromosomes during meiosis.
D Homologous chromosomes would be moving to the same end of the cell
Answer:
This question is incomplete as there is no diagram, however, the question can still be answered without it. the answer is as follows:
A. Each chromosome would still have two chromatids.
Explanation:
The ANAPHASE stage of both mitotic and meiotic division is the stage where chromosomes are pulled apart into opposite poles of the cell. However, meiosis occurs in a two-step division tagged meiosis I and meiosis II.
In mitosis, sister chromatids of a chromosome are separated during anaphase, but in meiosis I, homologous chromosomes are pulled apart during anaphase I. This means that in the anaphase I of meiosis as opposed to anaphase of mitosis, each separated chromosome WOULD STILL HAVE TWO CHROMATIDS.

The brown circle A shows neurotransmitters being absorbed, and the blue circle B shows neurotransmitters being
released.
Answer:
The brown circle A is a receptor, and the blue circle B is an effector.
Explanation:
The brown circle indicates a receptor whereas the blue circle is an effector because brown circle have sensory cells which receives the sensation due to pins into the foot and this information is taken to the central nervous system through sensory neurons while on the other hand, blue circle is an effector to which instructions comes from the central nervous system through motor neurons and as a result the dog pulls away its foot from the region where pin is placed.

A female fish may lay thousands of eggs at once. Which additional statement about fish is most useful for explaining how fish species can evolve by natural selection?
A. All of the fish eggs are genetically identical with one another and with the female parent fish.
B. The environment cannot support unlimited growth of the fish population, so only some fish eggs will mature to adults.
C. After the female fish lays a clutch of eggs, neither parent tends to or cares for the eggs or offspring.
D. Fish eggs will develop into embryos only if they are fertilized by sperm from the male fish.
Answer:
D
Explanation:
A can't be the answer since there is something called mutation which means even twins can't be 100% the same
B can't be since it has nothing to do with natural selection

Discuss in detail to process in which plants produce and use energy
Explanation:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
Compare and contrast gradualism and punctuated equilibrium. Provide at least one comparison and one difference in your answer. You may use examples for each if that helps you with answering the question.
Answer:
Gradualism and punctuated equilibrium both are the process of evolution of species over time. However, the gradualism process involves the evolution that occurred slowly, occurring in small periodic changes in the gene pool over a long period of time. Whereas Punctuated equilibrium takes place there are longer periods of apparent stasis interrupted by the sudden change.
They both help in finding the relative change in evolution rate and assist in the study of the anatomical changes occurred during the evolution in different kind of animals or organisms.
