Answers

Answer 1

The notion that we evolved from modern apes is wrong but we have evidence that humans evolved from apelike ancestors.

How did hominids evolve?

With time, genetic change can change the overall way of life of a specie like eating behavior, growth, and place of living. Human evolution took place when new genetic changes occur in the ancestor's populations which favor new abilities in that organisms to adapt to environmental change. Scientific evidence indicates that the physical and behavioral traits that are shared by all people come from apelike ancestors which evolved about six million years. One of the earliest defining human traits is bipedalism i.e. the ability to walk on two legs was evolved over 4 million years ago.

So we can conclude that hominids evolved because of the genetic change that occurs with time due to environmental change. We have many evidence that humans evolved from apelike ancestors due to environmental change.

a home made protocol for animal tissue DNA extraction?

Answers

DNA (deoxyribonucleic acid) is the hereditary material in almost all living organisms. Most DNA is located in the nucleus.

For extraction of DNA we need  500 ml water,91% Isopropyl Alcohol (rubbing alcohol),Dishwashing liquid, Salt, Food coloring (dark colors recommended),3 clear plastic cups

Steps include  Pour 500ml water in a plastic cup

2. Add one tablespoon of salt to the water

3.dissolved the salt completely

Transfer 2 tablespoons of salt water in a clear plastic cup

2. Vigorously trill the salt water

3. Spit salt water back into the same cup

When you trill the salt water, cheek cells will come out. Add 1ml of clear dishwashing soap to the salt .It will break open the cheek cells and their nuclei walls and this causes the DNA to be released into the salt water.

1. Pour 100 ml isopropyl alcohol plastic cup.

2. Add 3 drops of food coloring, and isopropyl alcohol  in a separate clear plastic cup.

2. Add 3 drops of food coloring, mix them well

DNA is insoluble in isopropyl alcohol so it will promotes the clustering of the DNA, making them visible.

White blood cells, called leukocytes, are very different in structure and function than red blood cells. White blood cells help fight infections, parasites, and bacteria. They do this by engulfing pathogens and synthesizing antibodies which are made from proteins. In addition white blood, cells can reproduce unlike red blood cells.

Answers

Many white blood cells can't divide and they have the ability to reproduce on their own.

How do white blood cells reproduce?

White blood cells are not similar to other types of cells that are present in our body. They act like single-cell organisms which can move on their own and can feed on other cells and bacteria. Many types of white blood cells can't reproduce on their own so they are produced in the bone marrow. In a person that has normal bone marrow, the number of white blood cells can double within hours. It is a type of blood cell that is produced in the bone marrow and found in the blood lymph tissue. White blood cells are part of the immune system of our body. White Blood Cell protects Red Blood Cell, as it tries to protect the red blood cells from pathogens.

So we can conclude that the cells which can move freely and feed on pathogens and bacteria that can harm our body are known as white blood cells.

Earth's ecosystem can be divided into 4 spheres, which are the atmosphere, the biosphere, the hydrosphere, and the geosphere. These spheres interact with each other and a change in one of them may cause a change in the other three spheres.

Answers

During the carbon cycle, organic matter can be used in multiple ways by different organisms, although, this chemical compound also can be buried underground and converted into peat, coal, oil, or gas deposits. This is possible due to organisms can store this material in their structures to grow, and eventually, when they decay, for example, when a tree or an animal dies, it begins to form part of the soil in which they were before. This is the reason why currently we can extract oil from underground sinks, because of those biggest organisms that lived millions of years ago, such as the dinosaurs and ancient plants.

Having this clear, we can say that the correct answer is the first one.

This is mostly found in the outer region of the cell membrane and is a rigid, semi-permeable protective layer which consists of lipids, cellulose and polysaccharides needed for its functions.

The cell wall is mostly found in plants but at the same time they are present in some cells of the body such as that of the skeletal muscular tissue due to the rigorous activities being performed by them.

Answers

Considering a food web flow chart, one element critical to building proteins as well as nucleic acids is nitrogen.

It gets into the mix of biomolecule elements by means of the nitrogen cycle.

What are biomolecules?

Biomolecules are large organic molecules found in living organisms. These biomolecules are essential for the fi=unctioning of living organisms.

There are four major biomolecules that are essential for life, they are:

proteins: proteins are the structural molecules of life. Proteins are composed of monomer units known as amino acids that are linked together by peptide bonds.lipids : lipids include the fats and oils which serve as energy stores as well as structural moleculesCarbohydrates : carbohydrates provide energy and also serve structural functions.Nucleic acids : nucleic acids are the DNA and RNA and they store genetic information.

One element critical in the formation of both proteins and nucleic acids is nitrogen. Nitrogen is present in all amino acids as the amino groups as well as in the side chain of some amino acids.

Nitrogen is also an important element in the structure of the nitrogenous bases of nucleic acids.

Answer: Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed.

Explanation: and this is what happens: The sliding of protein filaments is responsible for muscle contraction. When a motor neuron stimulates a muscle fiber, overlapping thick and thin filaments slide along one another and sarcomeres shorten. The combined shortening of many sarcomeres in many muscle fibers results in contraction of the whole muscle.

The Loch Raven Reservoir supports a variety of organisms at all times of the year. There is an algal bloom this year. How would the environment be expected to change?​

Answers

It is expected that the algal bloom in the Loch Raven Reservoir would change by decreasing the amount of available biomass.

What is the direct consequence of an algal bloom?

The direct consequence of an algal bloom is an increase in the amount of available oxygen in the aquatic system and a drastic reduction in the light that enters into this ecosystem, which reduces the amount of biomass because plants are unable to produce photosynthesis.

Therefore, we can conclude that the consequence of an algal bloom is a decrease in the biomass that supports the trophic chain in this aquatic ecosystem.
