what is zygote?

A zygote is a type of eukaryotic cell created when two gametes fertilize one another.

An organism's reproductive cells are called gametes.

They are additionally known as sex cells.

Male gametes are referred to as sperm, whereas female gametes are known as ova or egg cells.

During fertilization both male and female gametes are fused to form zygote. chromosome of both gametes are fused in zygote.

What does this graph tell you about the concentration of salt inside the cell?

Answers

The concentration of salt inside the cell was lower than the concentration of salt in the salt water, since the cell got much smaller in size due to water outward movement.

What is osmosis?

Osmosis is the movement of water molecules through a semi-permeable membrane from regions of low solute concentration to regions of high solute concentration.

If salt concentration is higher inside the cell than outside, water will move into the cells. However, if the salt concentration outside the cell is higher, water will move out of the cells.

The cell became smaller, indicating that water moved out of the cell.

Thus, the salt concentration in the cell was lower inside the cell.

In conclusion, water moved out of the cell by osmosis.

The rate of cellular respiration and photosynthesis can increase or decrease because of different factors.

Explain how either the rate of cellular respiration or the rate of photosynthesis can be increased and decreased. Be sure to include details of specific reactions in your answer.

Answers

The main environmental factors that affect photosynthesis are: light, CO2 and temperature. Also, the availability of water and nutrients are important factors.

How to increase the rate of photosynthesis?

Plants kept under ideal conditions of luminosity and carbon dioxide concentration increase the rate of photosynthesis as the ambient temperature increases, up to close to 40°C. Above this temperature limit, there will be a drastic reduction not only in photosynthesis, but also in most vital reactions.

The photosynthetic rate, that is, the intensity of photosynthesis that the plant performs, can be changed by the amount of light it receives. The greater this light radiation, the greater the photosynthetic rate, if there is no other factor such as temperature or water availability limiting the process.

A. Gravity
B. Weight
C. Mass
D. Eccentricity

Answers

D because of how its formed

D. The measure of how stretched out an ellipse is, is referred to as eccentricity.

What is eccentricity of ellipse?

Eccentricity for an ellipse is the ratio of the length of the semimajor axis (a) to the distance (c )between the ellipse's center and each focus.

e = c/a

The greatest ellipse has the smallest eccentricity, whereas the perfect circle has the maximum eccentricity. The eccentricity of an ellipse e, which ranges from 0 (the limiting case of a circle) to 1 (the length of the ellipse), is used to determine how long it is (the limiting case of infinite elongation, no longer an ellipse but a parabola). Because the distance from the fixed point on the plane has a constant ratio that is less than the distance from the fixed line on the plane, the eccentricity of an ellipse ranges from 0 to 1.

Early in genetic research, it was suggested that the genetic code might be made up of overlapping codons in which the last two bases of one codon make up the first two bases of the next codon, as below:
mRNA codons
overlapping code GGUAUA 1st codon = GGU
2nd codon = GUA

nonoverlapping code GGUAUA 1st codon = GGU
2nd codon = AUA

Supposing it were discovered that, in a life-form from another planet, even a single base pair substitution in the DNA caused three adjacent amino acid changes in the protein coded for. Would you conclude that the code was overlapping or nonoverlapping? Explain your logic.

Answers

The genetic code is called non-overlapping because adjacent codons can not overlap, whereas in this case, the code is overlapping.

What does 'overlapping code' mean?

The genetic code does not overlap because the same nucleotide in the sequence cannot be used to encode two different codons.

In genetics, overlapping refers to a feature of the genetic code associated with how this nucleotide code is read.

In conclusion, the genetic code in this case is overlapping.

However, prokaryotes, fungi, and some types of algae are not included in any modern definitions of the Plantae.

Plants are essential to the ecology because they help with the nitrogen cycle, prevent soil erosion, and participate in the water cycle. Although they also create oxygen, plants are a significant source of food. For humans to exist, it is essential that plants flourish.

One of the simplest methods to enhance the environment and enhance your surroundings is to plant a tree. Plants help to prevent soil erosion by filtering contaminants, absorbing carbon dioxide, and releasing oxygen. It will also assist to lessen your carbon footprint if you plant a few trees.

4 Starch tests show where photosynthesis has taken place. What can you conclude using the evidence from test 1?.
à5 What does the evidence from test 3 show? ​

Answers

1. Animals depend on plants to keep them alive is Plants are producers  they take energy from the sun, nutrients from the earth, and water to grow and have their flowers, seeds, and berries.

They also release oxygen, which all animals, including humans, need to stay. Animals are consumers and they all depend on plants for survival.

2. carbon dioxide and water reach the chloroplasts in leaves is Basically the roots consume the water and transports it up the xylem, which gets it to the leaves. Carbon dioxide contacts the chloroplasts in the leaves via a stomata

3. Two pieces of evidence that show that plants cannot make their own food without light. When plants lack light, they don't deliver chlorophyll (the green pigment in plants), and plants can turn pale green to yellow to white. Plant stems become “leggy,” meaning stems become long and thin and appear to be advancing toward the source of light.

The photosynthesis is the only method for synthesizing food. It is commonly believed that about 717.6Kcal energy is required to prepare just 10g of glucose. No energy input no metabolism and therefore no food.

Why is the sympathetic nervous system referred to as the fight or flight system?

Answers

As you can see from the diagram below, the human nervous system is divided into two main components, the peripheral nervous system and the central nervous system.

The peripheral nervous system is further divided into two components. The somatic nervous system involves the voluntary movement of skeletal muscle. When you decide to raise your cup of coffee to your mouth, that is the somatic nervous system at work activating the appropriate muscles. The second component of the PNS is the autonomic nervous system, which controls processes that are out of our conscious control.

The autonomic nervous system is further subdivided into the parasympathetic nervous system and the sympathetic nervous system (which you are interested in). In very generalized terms, they have antagonistic effects on each other. The sympathetic nervous system generally activates the body, whereas the parasympathetic nervous system primarily acts to relax the body. This is a simplified view of things, but it is useful to think of it in this way.

The sympathetic division of the autonomic nervous system increases heart rate, inhibits digestion, relaxes bronchi in the the lungs to allow more airflow, causes the release of glucose from the liver, and relaxes the bladder. All of this activates the body, prepares it for a "fight".

In contrast, the parasympathetic division reduces heart rate, constricts bronchi in the lungs, and increases blood flow to the digestive tract. It has been called the "rest and digest" system.

As you can see from the diagram, the nerves of the parasympathetic nervous system come directly from the brainstem and spinal cord. However, with the sympathetic nervous system, there are "ganglia" (groups of cell bodies) outside the spinal cord itself.

Interestingly, the parasympathetic nervous system only uses Acetylcholine (ACh) to exert its effects on organs, but the sympathetic nervous system uses both ACh and norepinephrine (NE) to activate the body.

Its important to remember that the sympathetic and parasympathetic nervous systems are autonomic, meaning we generally have little control over them.
