New findings suggest that, due to rising levels of carbon dioxide in the air and an increase in the acidity of the oceans, most coral reefs that exist today will disintegrate
by the end of the century. If carbon dioxide levels continue to rise, what is the most likely effect on marine organisms that rely on these reefs for food and shelter?
O Their numbers and diversity will be drastically reduced
O They will be able to use the area for shelter, but will have to travel to find food
O Their ability to reproduce will increase as competition for space decreases
O They will be forced to adapt to living in different areas

Answers

Option A. Their numbers and diversity will be drastically reduced

If carbon dioxide levels continue to rise and coral reefs disintegrate by the end of the century, the most likely effect on marine organisms that rely on these reefs for food and shelter would be a drastic reduction in their numbers and diversity (option a). Coral reefs serve as crucial habitats and nurseries for a wide range of marine organisms, including fish, invertebrates, and other species.

The disintegration of coral reefs would result in the loss of their structural complexity, which provides shelter, protection, and food sources for many organisms. Without the reefs, marine organisms would lose their primary habitats and face significant challenges in finding suitable alternatives. They may be forced to disperse over greater distances in search of food and shelter, which could result in increased predation risk, competition for limited resources, and reduced reproductive success.

Additionally, the decline of coral reefs would lead to a decline in available food sources, as the reefs support a diverse ecosystem with complex food webs. Organisms that rely directly or indirectly on the reefs for sustenance would face food scarcity and potential population declines.

Overall, the loss of coral reefs due to rising carbon dioxide levels would have a profound and negative impact on marine organisms, leading to reduced numbers and diversity, increased competition for resources, and potential disruptions to reproductive patterns. Therefore the correct option is A

the organisms that feed on dead and decaying matter are called
A. Saprotrophs
B. Autotrophs
C. Heterotrophs
D. Parasite ​

Answers

The organisms that feed on dead and decaying matter are called Saprotrophs.

An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms

Answer:

A. Saprotrophs

Explanation:

Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.

These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.

Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.

Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.

Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.

-Explain the mechanism of
water
Ascent in plants.


Answers

Answer:

Water ascent in plants, also known as transpiration, is the process by which water is transported from the roots to the leaves and other parts of the plant. It occurs through a series of interconnected tubes called xylem vessels, which are located in the stem and branches of the plant.

Explanation:

The mechanism of water ascent in plants involves several factors:

Capillary action: Water moves up the xylem vessels by a process called capillary action, which is the movement of a liquid along the surface of a solid due to the cohesive forces between the liquid and solid.

Cohesion and adhesion: Water molecules are attracted to each other (cohesion) and to the walls of the xylem vessels (adhesion). This causes water to form a continuous column that stretches from the roots to the leaves.

Evaporation: Water is lost from the leaves of the plant through the process of evaporation, which occurs when water molecules escape from the surface of the leaves into the air. This loss of water creates a negative pressure (tension) in the xylem vessels, which helps to pull more water up from the roots.

Root pressure: In some plants, root pressure also plays a role in water ascent. This is the hydrostatic pressure that is generated within the root cells as a result of the active transport of ions and nutrients into the xylem vessels. Root pressure can help to push water up the xylem vessels, especially when the soil is moist and there is a high demand for water by the plant.

what is the resting phase of the cell cycle called?

A. Prometaphase
B. Mitosis
C. Interphase

Answers

The resting phase of the cell cycle is called interphase.

Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.

This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.

Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.

Answers

"The derived shared characteristic 'Terrestrial during all stages' should be placed at the base of the tree diagram."

SupThe characteristic "Terrestrial during all stages" is a shared characteristic among all five species being compared in the branching tree diagram. This means that it is a characteristic that all of these species have in common, and therefore it is likely that it was present in their common ancestor.

Since the base of the tree represents the common ancestor of the species being compared, it makes sense to place this characteristic at the base of the tree. This also helps to show that this characteristic is a defining trait of the group of species being compared and that it has been present in their lineage since their common ancestor.

Answers

DNA and RNA have similarities in their nucleotide composition and involvement in genetic processes. However, they differ in their sugar type, strandedness, and specific functions in protein synthesis. Understanding these similarities and differences is crucial for comprehending the fundamental mechanisms of genetics and cellular processes.

RNA and DNA are both nucleic acids that play essential roles in genetic information and protein synthesis. However, they differ in various aspects.

DNA, or deoxyribonucleic acid, is a double-stranded molecule composed of nucleotides. It contains the sugar deoxyribose and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and thymine (T). DNA carries the genetic code and serves as the hereditary material in most organisms.

On the other hand, RNA, or ribonucleic acid, is typically single-stranded and contains the sugar ribose. RNA also consists of nucleotides, but it uses uracil (U) instead of thymine as a nitrogenous base. RNA has several forms, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Each form has specific roles in protein synthesis.

In terms of function, DNA stores and transmits genetic information, while RNA helps translate that information into proteins. DNA is primarily located in the nucleus of cells, while RNA is found in both the nucleus and cytoplasm.
