The hummingbird is more closely related to a lizard than it is to a dragonfly. Explain why two species that look similar are not necessarily closely related.

Answers

Answer 1
Some species look similar because they evolved in similar environments. Similar environments impose similar challenges, and traits improving survival are favoured. These organisms would not be closely related, however, because they evolved from different species and different regions. This is known as convergent evolution.

The individual blades are called leaflets. The leaflets are also referred to as

foliole.

The leaflets is referred to as the individual leaf and is usually not attached

directly to the main stem of the plants.

A simple leaf has only one blade while a compound leaf has two or more

The percentage of ATP production for a strength/power athlete during an aerobic activity during the first 10 seconds of the activity would be Question 7 options: 30 20 < 15 60

Answers

During aerobic activity, high number of ATP molecules are produced due to the addition of oxygen in it.

The percentage of ATP production for a strength/power athlete during an aerobic activity during the first 10 seconds of the activity would be higher than activity of anaerobic. Aerobic respiration process produces up to 38 ATP molecules per glucose as compared to anaerobic respiration produces only 2 ATP molecules per glucose.

This shows that aerobic respiration produces 15 to 20 times higher energy as compared to anaerobic respiration so we can conclude that during aerobic activity, high number of ATP molecules are produced due to the addition of oxygen in it.

Hebrews 11:7

Answers

Answer:

Faith, according to the Bible, is not blind. More than half of the verses in the book of Hebrews are dedicated to explaining reasons and evidence to accept the new covenant in Jesus Christ. Nor is faith gullible, or senseless. Instead, godly faith is exemplified by trust. That trust is based on what we know of God, relying on Him for the things we do not know. In particular, godly faith looks forward, from an eternal perspective, and produces obedience, even in the face of hardship. God takes what we cannot see, or cannot understand, and uses it to make good on His word. Since faith relies on what we've seen of God, and trusts Him for the future, it becomes the "assurance of things hoped for, the conviction of things not seen" (Hebrews 11:1–3).

Is cloning of endangered species a reliable and acceptable way to repopulate those ecosystems that suffer the loss of important species? Why or why not. (2 paragraph
minimum).

Answers

Cloning an extinct species is a possible answer for a suffering ecosystem. The only drawback is that scientists have not yet mastered cloning. When attempting to clone animals often they are deformed and therefore not able to reproduce let alone survive. Even when scientists do manage to clone animals without killing them, it takes many generations of selective breeding to get the species you are trying to revive which takes time, making the ecosystem even more damaged.

The study of a living being is called biology.

The correct answer is not reliable.

The duplication of the genes in the laboratory is called cloning.

The first clone species was the sheep whose name was a dolly.

Those species which are on the verge of extinction is called endangered species and they need extra protection to carry their gene to the next generation.

The cloning will be able to multiply the gene in the in-vitro culture but they will have a direct impact on the natural genes and the combination of the gene present in nature.

The natural species have all the desired genes which help them to survive in nature, whereas the clone species will not have the desired gene which is required to adapt to nature and they will extinct eventually. If these genes pass on to the next generation then the endangered species will also have less chance to survive in nature.

Hence, in my opinion, they cloning is not a suitable way to save endangered species.
