The statement about biomass energy is correct as the biomass energy is a nonrenewable resource that makes use of materials from recently living organisms and is present in Option A as it can end one day.

What is the significance of biomass energy?

Biomass energy uses organic materials, such as wood chips, agricultural waste, etc., and they release pollutants into the air that can occur during the burning of biomass, which can be mitigated through the use of modern, efficient combustion. Due to its low carbon emissions, biomass releases fewer carbon emissions when burned than fossil fuels.

Hence, the statement about biomass energy is correct as the biomass energy is a nonrenewable resource that makes use of materials from recently living organisms and is present in Option A as it can end one day.

Answers

The question is incomplete. The complete question is as follows:

The unusual patterns on a silk moth’s wings are one of the most stunning examples of mimicry in the wild. Mimicry occurs when an organism develops a physical characteristic or behavior similar to a protective trait in another species. What do you think these moth wings mimic? Why do you think this kind of mimicry can protect the moth?

Answer:

The silk moth's mimic the physical characteristics such as changes in wings pattern that resemble another moth species that is dangerous or unpalatable to predators.

This unusual change in wings pattern provide camouflage to the silk moths and prevent  predators. Predators get confuse because of the mimic spcies and consider them as toxic or untasty and won’t attack.

Answer:

The moth wings actually look like the eyes of a much larger animal. This mimicry may protect the moth from predators.

The correct answer is - option C.

Explanation:

A longitudinal wave with higher vitality have more noteworthy plentifulness. Abundancy is the separation between the covering and trough of the wave. The crust is the topmost layer of the wave while trough is present at the bottom portion of the wave.

In the event that the separation among crust and trough of the wave is higher so the amplitude is likewise more prominent and we can say that the wave contains a high measure of vitality and the other way around. The state of the structure of the wave simply like a hill.

Ash trees are being removed when they show signs of the ash borer, a parasite that affects only ash trees and kills them off. What best explains why the ash trees are being cut down? The ash borer is a density-independent limiting factor, and humans need to clear cut to control tree density. The ash borer is a density-dependent limiting factor and will start to spread to nearby healthy trees. Ash trees are outcompeting other trees and are thus more affected by the ash borer. Changes in climate have decreased ash borer populations which indirectly increased the need for cutting down the trees.

Ash borer is a parasite that affects ash trees it is highly destructive and invasive. It affects it Native host causing serious damages. Infected plant is cut down to avoid its spread to other healthy plant this is because ash bored when not control can destroy a whole population of ash trees in it Native environment within the space of 10 years.

B. Phosphate group
Hydrogen bonds
D. Nucleotide bases

Answers

Answer:

D. Nucleotide bases

Explanation:

Hope it helps.

Nucleotide bases of the DNA contain the instructions on how to control cells.

How does DNA control cells?The hundreds of distinct types of proteins that are produced by cells are coded by the nucleotide sequences that make up DNA. These proteins control and regulate cell development, division, communication with other cells, and the majority of other cellular functions. This is the reason why nucleotide sequences found in DNA are referred to as carrying or storing information.

Protein synthesis:

The sequences must first be "decoded," and the protein must then be translated. It is known as protein synthesis.

Transcription (first stage of protein synthesis): The process of copying information from a strand of DNA into a messenger RNA (mRNA) molecule is called transcription. DNA preserves genetic material as a reference or template safely and permanently in the cell nuclei.Translation (second stage of protein synthesis): The process of translation converts the information carried by messenger RNA from DNA into a string of amino acids. Essentially, it involves translating a code (nucleotide sequence) into another code (amino acid sequence).

Answers

Answer:

Explanation:

Biology, chemistry, and geology are the fields of science that provide evidence for evolution, hence option D is correct.

What is the evidence of evolution?

The uniformity of the fossil sequence from ancient to modern is possibly the strongest fossil evidence for evolution.

Fossils are a reflection of evolution and geological change due to their global distribution of organisms and distinctive traits of island species. The existence of species that are related to modern species but are now extinct is documented through fossils.

It is the series of slow, irreversible changes that occurred in early creatures over millions of years to give rise to new species we know today. Errors in DNA copying and sexual reproduction are mostly to blame for variations that led to the emergence of new species.

Therefore, biology, chemistry, and geology are the fields of science that provide evidence for evolution.

Answer:

In the process of respiration, energy is released from glucose molecules and stored in smaller ATP molecules.

Explanation:

Among carbohydrates, protein and fat, carbohydrates are metabolized first on respiration.  

Glucose first breaks into pyruvic acid (Glycolysis) Pyruvic acid forms acetyl coA (Link reaction)  Acetyl coA enters into the kreb cycle, where ATP is formed.  ATP formed through substrate level phosphorylation (direct ATP) and Electron transport chain (indirect ATP). NADH2 and FADH2 formed during respiration enters into ETC where they form ATP through oxidative phosphorylation.
