How does an ATP molecule release
energy for cells?
A. hydrolysis
B. breaking the bond between the 2nd and 3rd phosphate
C. removing the ribose sugar

Answers

Answer:

B

Explanation:

when one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released.

The ATP molecule releases energy for cells by breaking the weak phosphate bond and converting it to ADP. This process is called A. hydrolysis.

What is the hydrolysis of ATP? Our body requires energy to perform various body activities and functions. This includes muscle contraction, digestion, transportation of molecules etc. This energy comes from the breakdown of ATP. The ATP molecule that is generated during the respiration process is broken down into ADP. This process is called the hydrolysis of ATP. The energy that is released during the breakdown of ATP is used to perform the required functions. Out of the three phosphate bonds, the weak phosphate bond is broken down to fulfil the energy needs of the body.

Thus, whenever the cell requires energy, the ATP is broken down into ADP by the process of hydrolysis.

A symbiotic relationship in which one species benefits and the other is harmed is known as mutualism. predation. commensalism. parasitism.

Answers

Answer:

Parasitism

Explanation:

Example: Mosquitoes feed off the blood of a human and is benefitted, the human is harmed because the mosquitoe exposed he/she to malaria.

A symbiotic relationship in which one species benefits and the other is harmed is called parasitism. The parasite lives on the food of the host. Fourth option is correct.

What are different types of symbiotic associations?

In symbiosis, two organisms are present in close contact. There are different types of relationships seen in nature, such as mutualism, commensalism, parasitism, etc.

Mutualism occurs when two organisms, such as lichen, benefit from one another. Lichen is an association of algae and fungi. Algae makes food that is consumed by fungi, and fungi provide algae for a place to live.

In parasitism, one is the host, and the other is the parasite. An example is the tapeworm in the human intestine. Tape worms consume digested human food and harm humans by spreading their population. Here, the host is negatively impacted by the presence of parasites.

In predation, both are harmed as both are involved in the fighting. In commensalism, one party gets benefits while the other is not harmed by the association.

Hence, the fourth option is the correct answer, which is parasitism.

What classification fits it best?
A. Plantae
B. Animalia
C. Fungi
D. Protista

Answers

the answer is c fungi fits best

Multicellular is a cellular classification where the organism is made of more than one cell. The multicellular organism that absorbs nutrients best fits in the kingdom of Fungi. Thus, option C is correct.

What is Kingdom Fungi?

Fungi is one of the five kingdoms that are characterized by eukaryotic organisms with multicellular structures. They contain microorganisms that are heterotrophs and cannot make their own food. They absorb the nutrients from decaying organic materials.

The fungal mycelia and filaments called hyphae allow fungi like mushrooms and molds to absorb nutrients and minerals from the surrounding. They digest the nutrients with the help of enzymes.

Therefore, option C. the Fungi first digest then absorb nutrients from the environment.

What is exponential growth?

Exponential growth is a type of population growth pattern in which a population size increases at an accelerating rate, with each generation or time period adding a larger number of individuals than the one before it. This type of growth results in a population having a higher total number of members than it did in the previous generation.

To put it another way, the rate of population growth picks up steam over the course of time, producing a J-shaped curve when the data is plotted on a graph. This pattern can emerge when there is an abundance of resources available to a population but only a moderate amount of competition for those resources. This results in rapid reproduction and population growth as a result.

What is occurring in the diagram below?

A. Sister chromatids are separating.
B. Alleles are independently assorting.
C. Genes are replicating.
D. Segments of DNA are crossing over.

Answers

Answer:

D

Explanation:

The diagram below shows a portion of a chromosome during meiosis. Meiosis is a process of cellular division that produces haploid gametes from diploid cells. The process of meiosis involves two rounds of nuclear division.

What happens in the process of meiosis ?

During the first round, homologous chromosomes pair up and exchange genetic material. This process is known as crossing over.

The diagram below shows a section of the chromosome during the first meiotic division. The chromosome is composed of two sister chromatids, which are identical copies of each other.

These sister chromatids are held together by a centromere. At this stage, the sister chromatids are in the process of separating from each other. The arrows indicate the direction of movement of the chromatids as they separate. The diagram also shows a section of the chromosome where the two sister chromatids have already separated.

This section is known as a chiasma, and it is the result of crossing over. During crossing over, segments of DNA from the two homologous chromosomes exchange places. This process creates genetic variation in the gametes, which is important for evolution.

In conclusion, the diagram shows sister chromatids separating, alleles independently assorting, segments of DNA crossing over, but not genes replicating. The correct answer is A. Sister chromatids are separating.

at what point did the climate began to fluctuate more severely ? (2 points )

Answers

Answer:

Due to greenhouse gases.

Explanation:

When the high emission of greenhouse gases occurs, the climate began to fluctuate more severely because greenhouse gases such as carbondioxide gas and methane etc block the solar radiation that is reflected back to space which is responsible for the change of climate. If there is more greenhouse gases are emitted in the atmosphere so there is more fluctuation in the climatic condition of earth atmosphere so we can conclude that greenhouse gases leads to fluctuation of climatic conditions more severely..

Answers

Answer:

Aerial roots act as support to hold their tops above water.

Mangroves has leaves that contain glands, which expel salty water.

Explanation:

A mangrove is a shrub that grows in coastal saline or brackish water due to their salt tolerance abilities. Aerial roots act as support to hold the plant in water as well as provide oxygen to the plants. These aerial roots are present outside the water so that to provide oxygen to the plants directly absorb from the atmosphere. Mangroves leaves contain glands, which removes salty water from the body so due to these glands, mangrove is able to grow in saline water.
