Answers

Answer:

a. Glycolysis

b. actually, both plants and animals use glycolysis. They use these during cellular respiration and plant respiration

c. Heart tissue!

Explanation:

a.  Glycolysis produces 2 ATP per glucose molecule, and thus provides a direct means of producing energy in the absence of oxygen. Lactic acid, the end product of anaerobic glycolysis.

b. In organisms that perform cellular respiration, glycolysis is the first stage of this process. In plants, this metabolic process occurs in the cytosol and plastids of both photosynthetic and non-photosynthetic organs.

c. Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. In highly oxidative tissue, such as the heart, the production of pyruvate is essential for acetyl-CoA synthesis and L-malate synthesis.

What evidence is there that the 15 species of finch all evolved from one common ancestor?

Answers

Darwin’s Finches: Darwin observed that beak shape varies among finch species. He postulated that the beak of an ancestral species had adapted over time to equip the finches to acquire different food sources. This illustration shows the beak shapes for four species of ground finch: 1. Geospiza magnirostris (the large ground finch), 2. G. fortis (the medium ground finch), 3. G. parvula (the small tree finch), and 4. Certhidea olivacea (the green-warbler finch) the Grants measured beak sizes in the much-reduced population, they found that the average bill size was larger. This was clear evidence for natural selection of bill size caused by the availability of seeds. The Grants had studied the inheritance of bill sizes and knew that the surviving large-billed birds would tend to produce offspring with larger bills, so the selection would lead to evolution of bill size. Subsequent studies by the Grants have demonstrated selection on and evolution of bill size in this species in response to other changing conditions on the island. The evolution has occurred both to larger bills, as in this case, and to smaller bills when large seeds became rare.

All of them evolved from one rooted species, which colonized the islands only a few million years ago. This process, whereby species evolve rapidly to exploit empty eco-space, is known as adaptive radiation.

What is evidence of common ancestry and how do they explain evolution?

Homologous structures provide proof for a common origin, while analogous structures show that similar selective pressures can produce similar adaptations. Alikenesses and differences among biological molecules can be used to determine species' relatedness.

Thus, adaptive radiation is one of the reasons.

PLEASE HELP!!!! You discover a new protist species. It has chloro-
plasts and vacuoles and moves using a flagellum.
How would you classify the way that it gets energy?
Is it an autotroph, heterotroph, or both? Explain
your answer.

Answers

Answer:

Autotroph

Explanation:

An autotrophic organism is any organism that is capable of synthesizing its own food either by using sunlight (photosynthesis) as an energy source or chemicals (chemosynthesis). An organism capable of photosynthesis must possess CHLOROPLAST (CHLOROPHYLL), which is responsible for capturing sunlight in the cell and also harbors the photosynthetic process.

According to this question, a newly discovered protist is said to have chloroplasts and vacuoles and moves using a flagellum. Due to the fact that this protist possess CHLOROPLAST organelle, it means it can perform photosynthesis, which is one of the ways an autotrophic organism synthesizes it's food. Hence, the organism is AUTOTROPHIC.

Answers

Answer:

Look at the graph...What is the optimal temperature for this enzyme?


A. 60 degrees C

B. 45 degrees C

C. 15 degrees C

D. 35 degrees C

Answers

Answer:

B: 45 degrees C

Explanation:

However, above 40-45 degrees Celsius, enzymes are usually denatured and can no longer catalyse the reaction, because the hydrogen bonds are broken, so the enzyme permanently loses its shape. The temperature at which the reaction rate is fastest is the optimum temperature.

As per the graph, the optimum temperature for the enzyme is 45 degree Celsius. The correct option is C.

What is optimum temperature?

The temperature at which the enzyme exhibits the greatest activity is referred to as the optimum temperature.

Enzyme activity decreases as the temperature rises or falls. It can even become inactive at times. It is equivalent to the body temperature of a warm-blooded animal.

The kinetic energy in the substrate and enzyme molecules is optimal for the maximum number of collisions at the optimal temperature.

At high temperatures, the enzyme's shape changes, and it no longer complements its specific substrate.

It is the temperature at which the enzyme's reaction rate is fastest. It will be the point on the graph where the line reaches a peak at 45 degrees Celsius.

Thus, the correct option is C.

Answers

Answer:

C) The types of plants and animals that live in the forest are reasonably stable.

The statement that describes a forest ecosystem that has not experienced any natural disasters in the past 100 years is, "The types of plants and animals that live in the forest are reasonably stable," hence option C is correct.

What is a forest ecosystem?

Along with nonliving (abiotic) elements like soil, water, air, and landforms, forests also contain living (biotic) elements like trees, animals, plants, and other life things. A forest ecosystem is made up of all of these elements.

The numerous plant and animal species residing in a forest ecosystem are generally stable if it has not recently been subjected to any disturbances or natural disasters.

Therefore, plants and animals that live in the forest are reasonably stable, so this ecosystem not experienced any natural disasters.
