Explanation:
An enzyme is a protein that speeds up a chemical reaction. Enzymes are shape specific. The active site is a specific shape, which means it can only break down specific substrates.
Certain conditions can denature enzymes. For example, extreme temperatures or pH will cause the enzyme to deform and change shape, which means it cannot perform its job.
Therefore, the best choice is the second one: enzymes work best in specific conditions and only break down specific substrates.
How does a decrease/decline in a top predator impact biodiversity in an ecosystem?
Answer:
The most obvious result of the removal of the top predators in an ecosystem is a population explosion in the prey species. ... When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other. When the predators are removed, prey populations explode.
How does the atmosphere act like a greenhouse? 7th grade science
Answer:
The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat just like the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. ... At night, Earth's surface cools, releasing heat back into the air.

What color is ragweed pollen
Answer:
A yellow-green.. Just search it up.
Explanation:
The color which can be attributed to the ragweed pollen when it is been analyzed can be regarded as greenish yellow.
How can the color of ragweed be described?Ragweed has tiny heads of greenish yellow blooms that produce large amounts of pollen that is dispersed by the wind rather than insects. While ragweed blooms are not particularly eye-catching, it is frequently simpler to identify these plants by their stems and leaves.
In the aster family, Asteraceae, the genus Ambrosia contains flowering plants known as ragweeds. They are found across the Americas' tropical and subtropical climates, particularly in North America, where the southwestern United States and northwest Mexico are the genus's origin and diversity core.

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. It can significantly be divided into two phases. They are as follows:
Interphase.M-phase (Division phase).The Interphase of the cell cycle is the longest phase which consists of three phases. They are the G1 phase, S-phase, and G2 phase. In this phase, the cell replicates its genetic content and appears to be in a normal state.
In metaphase, the chromosomes usually align in one plane and form an equatorial plate. Anaphase is the smallest phase of mitotic cell division. In this phase, the centromere splits, and centromeres migrate to opposite poles.
In telophase, two sets of daughter chromosomes reached the opposite poles and are converted into chromatin thread. After karyokinesis, the cytoplasm gets converted into two equal parts. This is known as cytokinesis.
Therefore, the letter answers to the matching image is well described above.

Which list gives the complete path for pollen as it fertilizes a plant?
stamen - pistil - anther - ovary
stamen - anther - pistil - ovary
anther - stigma - style - ovary
anther - style - stigma - ovary
Answer: 3
Explanation:
The complete path for pollen as it fertilizes a plant anther, stigma, style, and ovary. Thus, option C is correct.
What is anther, stigma, style, and ovary?Anther is known as the part of a stamen and it that produces and it does contain pollen and it is usually borne which present on a stalk which shows the illustration. Anther is known as the part present in the stamen in which the pollen has to produced.
Style is known as the tube shaped structure which has the function of support to the stigma. The main function of the style has to assist the procedure of the fertilization as well as giving permission of pollen tube that travel in the delivery of the sperm cells in the egg.
Ovary is known as the basal enlarged part of the pistil, and it is known as the flower's female organ. The ovule is present in the ovary later it develops into the seed just after the process of fertilization. The main character of ovary is that it matures and develop into the fruit.
Therefore, The complete path for pollen as it fertilizes a plant anther, stigma, style, and ovary. Thus, option C is correct.

what is the flow of energy in an ecosystem.
Answer:
The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.
