Complete the statements to identify the first two steps of meiosis I.
The first and longest step of meiosis I is called
I.
The second step of meiosis I is called
I.
Answer:
Prophase I
Metaphase I
Explanation:
One of the methods of cell division that results in four daughter cells is called meiosis. These cells have half of the number of chromosomes when compared to the parent cell. The sub-phases are prophase, metaphase, anaphase, and telophase. So the first and longest step is called prophase and the second step is called metaphase.
Answer:Prophase!Metaphase I!

When an earthquake occurs within Earth’s crust and sparks a tsunami, energy is transformed. Describe the transformations that occur in this example.
Answer:
Potential energy into kinetic energy.
Explanation:
The uplifting of water occurs due to earthquake in the sea floor is refers to potential energy while on the other hand, the movement of water to the land in the form of waves is the kinetic energy. So we can see that the transformations of energy occurs from potential energy due to earthquake into kinetic energy occurs due to movement of water in the form of giant waves (tsunami).

Some entomologists believe that the evolutionary reason that plants expend energy to produce fall color is to warn pests. A plant that is healthy is able to produce lots of carbohydrates, and therefore more anthocyanins. Some insect pests will not lay eggs on bright colored leaves. Instead, they will find a “weaker” drab/dull colored tree on which to lay eggs. Some scientists believe that anthocyanins may act as a sunscreen to inhibit the destruction of the chlorophyll, help to prevent frost injury to leaf tissues, or limit water loss during dry spells in autumn. As far as the fall foliage watcher is concerned, their purpose is simple—they signal a last hurrah for the growing season and delight the optic nerve.
Summarize the last paragraph to explain the proposed evolutionary reasons that plants produce fall color in 30 words or less.
Answer:
How do trees turn color?
In the fall, trees break down the green pigments and nutrients stored in their leaves. The nutrients are shuttled into the tree's roots for reuse in the spring. It's then that the trees take on their autumn hues. As leaves lose their chlorophyll, other pigments become visible to the human eye, according to Bryan A.

The Arizona poppy is a plant that is native to the Southwestern United States. Its orange flower blooms in the summer and the plant is covered in small hairs. It is an important part of an ecosystem because at least 46 different species of insects visit the flower for food. The Arizona poppy has adapted to living in areas that receive less rain, but there are still periods of time that a drought occurs. What part(s) of photosynthesis would the plant not be able to perform if there were no rain? What would be the long-term effects on the plant if the drought continues? Explain your answer.
Answer:
See explanation
Explanation:
There are three main aspects of photosynthesis
(i) Absorption of light energy by chlorophyll.
(ii)Photolysis of water
(iii) combination of water and CO2 to form carbohydrates.
The second and the third aspects of photosynthesis are controlled by the availability of water. Plants absorb water from the soil through their root hairs and it moves up to the leaves by capillary action.
Hence, if there is no rain (drought), the soil will lack water and so does the plant thereby hindering the uptake of water for the second and third stages of photosynthesis.
the Arizona poppy, lie dormant during drought only to germinate, grow, flower, and yield seeds a few weeks after the rains return.

Describe what happens during each event
in interphase:
· First gap:
· Synthesis:
· Second gap:
Answer: There are three stages of interphase: G1 (first gap), S (synthesis of new DNA ), and G2 (second gap).
Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied.
The cell grows and carries out biochemical functions, such as protein synthesis, in the G1 phase.
During the S phase, DNA is duplicated into two sister chromatids, and centrosomes, which give rise to the mitotic spindle, are also replicated.
In the G2 phase, energy is replenished, new proteins are synthesized, the cytoskeleton is dismantled, and additional growth occurs.

What are the four major categories of Marco molecules? Describe the basic structures and primary functions of each
Answer:
Explanation:
question 1:
Biological macromolecules are large molecules, necessary for life, that are built from smaller organic molecules. There are four major classes of biological macromolecules. these are carbohydrates, lipids, proteins, and nucleic acids. Each is an important cell component and performs a wide array of functions.
question 2:
Carbohydrates
Carbohydrates are, in fact, an essential part of our diet; grains, fruits, and vegetables are all natural sources of carbohydrates. Carbohydrates provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. Carbohydrates also have other important functions in humans, animals, and plants.
Lipids
Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon–carbon or carbon–hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals.
Proteins
Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective; they may serve in transport, storage, or membranes; or they may be toxins or enzymes. mail me via at 16jacktwinwritters for more explanation and further clarification. Each cell in a living system may contain thousands of proteins, each with a unique function. Their structures, like their functions, vary greatly.
Nucleic Acids
Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.

Provitamin A, also known as beta-carotene, is necessary for human health. People who do not make this substance suffer serious medical problems. Which application of genetic technology has been the MOST promising for treating people who suffer from a deficiency of provitamin A?
Answer:
The application of genetic engineering called golden rice
Explanation:
Golden Rice is a genetically engineered biofortified crop designed by biosynthesizing beta carotene in the edible part of rice. Golden rice was created by transforming rice with two beta-carotene biosynthesis genes: psy (phytoene synthase) from daffodil ('Narcissus pseudonarcissus') crtI (phytoene desaturase) from the soil bacterium Erwinia uredovora.
Golden rice was genetically modified to provide beta-carotene, which is converted into vitamin A in the body, which is an essential nutrient that white rice lacks.
Which of the following statements best describes interphase?
Interphase is made up of the M and C phase and is the portion of the cell cycle where the nucleus divides.
Interphase is made up of the G1, S, and G2 phase and is the portion of the cell cycle where cellular contents are duplicated.
Interphase is made up of the G1, S, G2, M, and C phase and is the portion of the cell cycle where two new daughter cells are formed.
Interphase is made up of the C, G1, S, and G2 phase and is the portion of the cell cycle where the genetic information is exchanged between chromosomes during cell division.
The statement that best describes the interphase of the cell cycle is as follows:
The Interphase is made up of the G1, S, and G2 phases and is the portion of the cell cycle where cellular contents are duplicated.Thus, the correct option for this question is B.
What is the Cell cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The cell cycle can be divided into two phases. They are as follows:
Interphase.M-phase (Division phase).Interphase is the first phase of the cell cycle that is again divided into three sub-phases.
G1 phase: It is the resting phase. This is because no synthesis of DNA occurs in this phase. It is involved in the synthesis of RNA and proteins. S-phase: During this phase, replication of DNA takes place along with histone proteins. So, it is also known as the synthesis phase. G2 phase: This is the second gap phase. In this phase, the synthesis of RNA and proteins continues.Therefore, the correct option for this question is B.

In a signal transduction pathway, fine tuning of the cellular response occurs in several steps. Which of the following best describes how the response would be affected if the molecular changes that occur during a signaling pathway lasted for a prolonged period?
Inactivation mechanisms would be triggered before the pathway could be completed.
Receptors would be unable to return to their inactive form and respond to new signals.
Scaffolding proteins would cause potentially harmful signal amplification in the cytosol.
Signaling proteins would be unable to take part in multiple pathways, as specificity is lost.
Answer: Receptors would be unable to return to their inactive form and respond to new signals.
Explanation:
Many signaling pathway involves the regulation of the protein synthesis. It involves the turning off or on of some of the specific genes present in the nucleus. If the receptors become unable to resume to the inactive form the may not be able to produce new signals during protein synthesis. The final activated molecule in a signal pathway may not function as transcription factor.
Answer:
Receptors would be unable to return to their inactive form and respond to new signals.
