Why fission, regeneration and fragmentation, all are considered as methods of asexual reproduction ?​

Answers

Fission (binary and multiple), regeneration and fragmentation are considered as methods of asexual reproduction because all of them involve only one parent and gametes are not formed in them. New individuals produced after cell division are always genetically identical or clone to their parents.

Explanation:

A group of researchers has made the claim that one particular butterfly species is the sole pollinator of a tree species and that consequently, the decline of the butterfly population will endanger the survival of the tree species. Data were collected and are summarized below. Which of the following data could best be used to either justify or refute the claim the researchers have made about the interdependence of the butterfly species and the trees?

Tree flower size Number of butterfly visits per flower per day Nectar energy per pollination visit (joules) Fruits per flower
Small 1 10 0.88
Medium 9 12 0.79
Large 55 13 0.85

a. The data comparing the fruits produced per flower with the number of butterfly visits are most useful in refuting the claim, because they show that the tree produces fruit even if the butterfly does not visit the flowers.
b. The data collected for large flowers are most useful in justifying the claim, because they show that a large number of butterflies visit flowers of this tree species, obtain energy from nectar, and cause fruit production.
c. The data comparing the number of butterfly visits with the size of the tree flowers are most useful in refuting the claim, because they show that the butterfly does not visit all types of tree flowers.
d. The data showing the nectar energy available for all sizes of flowers are most useful in justifying the claim, because they show that butterflies benefit from the relationship with the tree by obtaining energy from tree nectar.

Answers

Answer:

The correct answer is - A. The data comparing the fruits produced per flower with the number of butterfly visits are most useful in refuting the claim, because they show that the tree produces fruit even if the butterfly does not visit the flowers.

Explanation:

In this experiment, the table shows that specific butterflies did not go to small flower trees or go once a day where is in medium and large flower trees respectively they visit more than small flowers.

Even after not visiting small flower trees the nectar energy and the fruit production is almost similar to the other two trees. This case can occur only in one case if there are one or more pollinators present in this scenario other than this type of specific butterflies.

Thus, the correct answer is - option A.

Identify all statements that accurately describe the structure of the pyruvate dehydrogenase (PDH) complex. E2 contains three domains. The complex contains multiple copies of each of three enzymes. A regulatory kinase and phosphatase are part of the mammalian PDH complex. The core of the complex is made up of several copies of E1 . Several copies each of E1 and E3 surround E2 .

Answers

Answer: The statements that correctly describe the structure of pyruvate dehydrogenase (PDH) complex are:

--> E2 contains three domains.

--> A regulatory kinase and phosphatase are part of the mammalian PDH complex.

--> Several copies each of E1 and E3 surround E2 .

Explanation:

Enzymes are proteins that speeds up a metabolic reaction by lowering the amount of energy needed to start the reaction. The type of enzyme in a cell will determine the metabolic processes that will occur in it.

Pyruvate dehydrogenase complex which is located at the mitochondria matrix, is a group of enzyme that catalyzes the breakdown of pyruvate, which is the end product of glycolysis, to form acetyl-CoA. The product formed from the reaction which is acetyl-CoA in turn enters the citric acid cycle where it is further oxidized for cellular respiration.

The structure of Pyruvate dehydrogenase complex consists of:

--> Three catalytic enzymes: These include;

• E1: This is the first enzyme of the PDH complex called pyruvate dehydrogenase. It catalyzes the removal of one carbon atom from pyruvate which leads to the production of hydrohyethyl.

• E2: This is the second enzyme of PDH complex called dihydrolipoamide S-acetyltransferase. It catalyzes the transfer of hydroxyethyl group to oxidized form of covalently bound lipoamide, and the resulting acetyl group is then transferred to free coenzyme A to form ACETYL-CoA and reduced dihydrolipoamide. Several copies each of E1 and E3 surround E2 and it consist of three DOMAINS. These domains include: N-terminal 9 kDa lipoyl domain, 4 kDa peripheral subunit-binding domain and C-terminal 28 kDa catalytic (acetyltransferase) domain.

• E3: This is the third and last enzyme of PDH complex called the flavoprotein dihydrolipoamide dehydrogenase. It re-oxidizes the lipoyl group of dihydrolipoamide-E2 to form lipoamide-E2 and NADH.

--> Two regulatory enzymes: The activities of E1 which is the rate limiting step of PDH complex regulated by phosphatases (activators) and kinases (inhibitors).

--> A binding protein: these aids in the binding of E2 to E3 enzyme in the core of PDH complex.

Explain how this would demonstrate Boyle's Law. Explain Boyle's Law in terms of the kinetic energy of molecule

Answers

Answer:

The correct answer is -  would be double which is 1472 mm Hg.

Explanation:

According to Boyle's law that says the relationship between volume and pressure of a gas at constant pressure shows an inverse relationship which means if volume will increase then pressure will be decrease and vice versa.

P1V1 = P2V2 .........Boyle's law

Given: P1 = 736 mm Hg

          V1 = 50 mL

P2 = ?

V2 = 25 mL

Solution:

from the Boyle's law

(P1V1)/V2 = P2

736×50/25 = P2

P2 = 1472

So the decreasing the volume to half increases the pressure double. It proves it follows Boyle's law

What is Ecosystem?

An ecosystem, also known as an ecological system, is made up of all the organisms and the physical setting in which they live. The nutrition cycles and energy flows connect these biotic and abiotic elements.

Photosynthesis is how energy enters the system and is absorbed by plant tissue. Animals play a significant part in the transfer of materials and energy through the system by eating plants and one another.

In addition to facilitating nutrient cycling by transforming nutrients held in dead biomass back into a form that can be easily utilised by plants and microorganisms, decomposers also release carbon into the atmosphere through the breakdown of dead organic matter.

Therefore, Energy used by decomposers are the ecosystem obtain energy and nutrients from plants.

Answers

Answer:

3.) How do you know when the first day of the menstrual cycle is? What happens?

A.) first day of menstrual bleeding is considered Day 1 of the cycle.

4.) What is the function of FSH?

A.) FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries.

-TheUnknownScientist

Answer: 3. Day 1 of your cycle is the first day of your period, meaning the first day of full flow (spotting doesn't count). During this time, the uterus sheds its lining from the previous cycle. Between days 1 – 5 of your cycle, new follicles (sacs of fluid containing eggs) begin to develop within your ovaries. 4. FSH plays an important role in sexual development and functioning. In women, FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries. FSH levels in women change throughout the menstrual cycle, with the highest levels happening just before an egg is released by the ovary.

Meiosis is a type of cell division that is specific to

Answers

Meiosis is a type of cell division that is specific to germ cells (gamete cells).

What is Meiosis?

Meiosis may be defined as a type of cell division in which each parental cell is divided into four daughter cells. Each daughter cells are genetically unique to the parental cell and are haploid in nature.

Gamete cells are typically divided by this mechanism of cell division. This is because when toe distinctive gamete cells from male and female are fused together, the resultant zygote will have the entire set of genetic material.

The gamete cells significantly have half the amount of genetic content. Due to this, it is also known as reductional division.

Therefore, meiosis is a type of cell division that is specific to germ cells (gamete cells).

Identify the process(es) represented by 1 and 2. State how these processes (1 and 2) affect the amount of genetic information provided by a parent to its offspring.

Answers

Answer:

The diagram below represents some stages in the life cycle of humans. The numbers in the diagram represent various processes in the cycle.

1. "The processes reduce the amount of genetic information from each parent by half."

During sexual reproduction, a specialized cell division process called meiosis occurs. Meiosis involves two consecutive divisions, resulting in the production of four haploid cells (gametes) from a diploid cell.

2. "Each parent only contributes half of the genetic information that is contained in his or her own cells."

As mentioned earlier, meiosis results in the formation of haploid gametes. Each gamete contains only one set of chromosomes, which is half the number found in the parent's diploid cells.

During meiosis, homologous chromosomes pair up, and genetic recombination occurs between them, shuffling and exchanging genetic information.

3. "Each egg (or each sperm) will carry only half of the genetic information contained in the parent's body cells."

This statement reiterates that gametes (eggs or sperm) are haploid cells containing only one set of chromosomes. When a cell undergoes meiosis to produce gametes, it divides twice, resulting in four cells with half the genetic information of the parent's body cells.
