why are vitamins important to enzymes and what this relationship is called?

Answers

The activity of some enzymes requires vitamins. This is because vitamin derivatives contribute to the biochemical mechanisms of these enzymes. These vitamin derivatives belong to a class of molecules known as cofactors, which are organic molecules (called coenzymes) or metallic ions, that assist in the catalytic activity of an enzyme.

Why are organisms that reproduce sexually less likely to accumulate deleterious mutations ?

Answers

Sexual mode of reproduction is considered to be better than the asexual mode of reproduction. This is because, in asexual reproduction, the only single parent gives rise to another offspring which is exactly similar to the parent as it passes its genetic material to the offspring.

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.

➥ The chromosomes are thin, slender and long.

➥ Chromosome number is diploid.

Zygotene

➥ Corresponding chromosomes become intimately associated.

➥ The process of pairing is known as synapse. It is so exact that pairing is not merely between corresponding chromosomes but between corresponding individual units.

➥ The chromosomes become shorter and thicker.

Pachytene or Pachynema

➥ The synaptic chromosomes become very intimately associated.

➥ The pair of chromosomes becomes short and thick.

➥ Crossing over occurs at this stage. Chiasmata are clearly seen.

Diplotene

➥ Homologous chromosomes start separating from one another.

➥ Chiasmata tend to slip out of the chromosomes. This is known as terminalisation of chiasmata.

➥ Chromosomes start separating out but the separation is not complete.

➥ Nuclear membrane and nucleolus start disappearing.

Diakinesis

➥ The bivalents condense further and get randomly distributed.

➥ The separation of paired chromosomes is almost complete.

➥ Terminalisation of chiasmata is almost complete.

➥ Nuclear membrane and nucleolus disappear.

C.
The types of plants and animals that live in the forest are reasonably stable.
D.
The number of types of animals that live in the forest is rapidly increasing.

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.

Answers

Answer:

Changes in genetic makeup occurs with the passage of time.

Explanation:

Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.

b Sexual
C Mitosis

Answers

Answer:

Sexual

Explanation:

Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.

Hope it helps

Answer: Sexual, I believe.

Explanation:

If it were Asexual, it'd only involve one parent. Mitosis has daughter cells have the same number of chromosomes as parent cells (heavy emphasis on cells as in plural cells.) And replication is just copying a cell.

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.
