Answer:

The components of the fluid connective tissue are red blood cells, white blood cell and blood platelets

Explanation:

The connective tissues refer to tissues composed of some class of matrix. The blood is considered a fluid connective tissue which is composed of red blood cells (erythrocytes), white blood cell (leukocytes) and blood platelets (thrombocytes). Erythrocytes are cells that contain hemoglobin and whose function is to transport oxygen to the body. Leukocytes are cells involved in the immune responses which act to protect the body against both foreign pathogenic invaders. Finally, thrombocytes are cell fragments that form clots and stop bleeding.

An intragenic inversion refers to an inversion event that occurs within a single gene on a chromosome.

An intragenic inversion refers to an inversion event that occurs within a single gene on a chromosome. As a result of this inversion, several possible outcomes can arise.

Firstly, the order of genes along the chromosome may be altered, disrupting the normal sequence. Secondly, the inversion can cause rearrangement of the gene's DNA sequences, leading to some segments being adjacent to DNA sequences they are not normally connected to.

These changes can impact gene expression and function. However, it is important to note that despite the inversion, the individual bases (A, C, G, and T) within the gene generally remain in the same order as normal. Therefore, the correct options are A, C, and D.

Answer:

Oestrogen and progesterone in the control of the menstrual cycle. Progesterone maintains the uterus lining (the thickness of the uterus wall). If the egg has not been fertilised, the corpus luteum dies and progesterone levels drop. This causes menstruation, where the uterus lining breaks down - this is known as having a period.

The two major issues with our reliance on nonrenewable energy sources are environmental pollution and dwindling supplies.

Environmental pollution and dwindling supplies are two major issues with our reliance on nonrenewable energy sources because burning of fossil fuels release carbondioxide which is a pollutant. This fuel is present in limited countries but its consumption is very high. Sometimes they can't match the demand.

So we can conclude that the two major issues with our reliance on nonrenewable energy sources are environmental pollution and dwindling supplies.

There is exponential bacterial growth. It was calculated that there were 5. 5 X 10^4 cells present at 7:00 AM.  As a result, the bacteria's generation period is roughly 29.3 minutes.

Here: N = \(N_{0}\) x 2^(t/g)

Here:

\(N_{0}\) = initial number of cells

N = final no's of cells

t = time elapsed

g = generation time

We can use the information given to solve for g.

At 7:00 AM, \(N_{0}\) = 5.5 x 10^4 cells

At 11:00 AM, N = 8.7 x 10^7 cells

The time elapsed is 4 hours, or 240 minutes.

Substituting these values into the formula, we get:

8.7 x 10^7 = 5.5 x 10^4 x 2^(240/g)

Dividing both sides by 5.5 x 10^4, we get:

1582.7 = 2^(240/g)

Taking the logarithm of both sides (base 2), we get:

log (base 2) (1582.7) = 240/g

Solving for g, we get:

g = 240 / log2(1582.7)

Calculating g, we discover that it is roughly 29.3 minutes. As a result, the bacteria's generation period is roughly 29.3 minutes.

Answer:

Photosynthesis is the process by which green plants absorb light energy from the sun with the assistance of water and carbon dioxide, and transform it into chemical energy to make (synthesize) carbohydrate (specifically glucose) and oxygen.

The "light-independent" or dark reactions happen in the stroma of the chloroplasts. This is also known as the Calvin Cycle. Since these processes can only happen in the chloroplast (a chlorophyll filled plastid in green plants), photosynthesis can only happen in green plants!

The first overall principle of photosynthesis is that the light energy from the sun is transformed into chemical energy and stored in the bonds of glucose (the sugar carbohydrate) for later use by the plant and/or organism that eats the plant.

The second overall principle of photosynthesis is that carbon, oxygen, and hydrogen atoms are taken from carbon dioxide and water molecules and are broken up and rearranged into new substances: carbohydrate (specifically glucose) and oxygen gas (so we can breathe, whew!). This reaction represents the transfer of matter: carbon dioxide from the atmosphere, water from the soil or atmosphere, into sugar in the plant and oxygen back into the atmosphere.

Light-Dependent Reactions

The first part of the process happens in the thylakoids of the chloroplasts and are the "light-dependent" reactions: The photosystems I and II absorb the photons from the sunlight and process them through the membranes of the thylakoids simultaneously. The photons excite electrons in the chlorphyll which then move through the electron transport chain and causes NADP- to combine with H+ forming NADPH. At the same time, ADP (adenosine diphosphate) has come from the dark reaction and a third phosphate chain is bonded forming ATP (adenosine triphosphate) to feed the Calvin Cycle next. Remember that ATP is the important source of all cellular energy.

We now believe that all the oxygen released in photosynthesis comes from the water molecules and all oxygen atoms that form the carbohydrates come from the carbon dioxide molecules. So, in other words during the light-dependent reaction a water molecule is broken down producing two H+ ions and half an oxygen molecule. We get the rest of the oxygen molecule when another water molecule is broken down.

Dark Reactions

Dark reactions are also known as the Calvin Cycle, the Calvin-Benson cycle, and light-independent reactions. The point is that they do not require sunlight to complete their process.

After ATP is formed in the first part of photosynthesis, for living things to grow, reproduce and repair themselves, the inorganic form of CO2 must be transformed into carbohydrate. This happens during the Calvin Cycle in the stroma (the fluid filled interior of the chloroplast). ATP and NADPH combine with CO2 and water to make the end product of glucose. The ADP and NADPH+ are recycled to the light-dependent side to start the process over.

Remember that during hours of darkness, plants cannot perform photosynthesis so they do cellular respiration in the mitochondria just as all living organisms do.

Turgor pressure is a phenomena that occurs in plant cells where the cell expands as a result of pressure from the fluids and the contents of the cell on the walls.

Since the external pressure is typically very high and the internal pressure dilates the cell as far as the flexibility of the membranes permits, it is similar to osmosis. The membranes then become tense due to pressure as the cells swell by absorbing water. Turgor pressure is the term used to describe the force that the fluid applies to the cell wall. Nevertheless, wall pressure refers to the internal pressure that the stretched cell wall produces on the contents of the cell. In most cases, the turgor pressure and the wall pressure are balanced and counterbalanced.

Hence, the turgor pressure helps the plant's cells elongate, and the cells also employ this phenomenon to control transpiration by opening and closing the stomach.

Hence, three main elements have an impact on a living cell's turgor:

Water is held in vacuoles, which are organelles in plant and fungus cells that are surrounded by a single membrane. Water flow into or out of vacuoles allows plant cells to regulate their turgor pressure. When water is provided to wilted plants, it enters the cell and creates turgor, giving the plant a firmer appearance. This water is then held in the vacuoles.

The incorrect statement concerning evaporation is: "Increasing the surface area of the liquid decreases the rate of evaporation." Option A is correct.

In reality, increasing the surface area of the liquid actually increases the rate of evaporation. This is because evaporation occurs at the surface of the liquid, and a larger surface area provides more space for molecules to escape into the vapor phase. Evaporation is a process by which a liquid changes into a gas or vapor state.

It occurs when molecules near the surface of a liquid gain enough energy to overcome intermolecular forces and escape into the surrounding space as vapor. Increasing the temperature of the liquid is one of the factors that can significantly affect the rate of evaporation. As the temperature rises, the average kinetic energy of the molecules increases, resulting in more molecules having sufficient energy to transition from the liquid to the gas phase, option A is correct.

The characteristics of a true-breeding plant line include;

a) in most cases, is homozygous for the trait of interest

d)when selfed, all of the offspring show the trait of interest

A pair of homozygous parents, known as purelines, who cross and have identical offspring as a result constitute a true breeding plant.

Homozygous recessive parents give birth to recessive children, and homozygous dominant parents give birth to dominant children. Parents that are both homozygous dominant and recessive give birth to dominant children.

When these are selfed, the identical qualities (trait of interest) are produced once more. Most of the time, a genuine breeding plant is homozygous for the desired trait, and when selfed, all of the offspring will exhibit the desired characteristic.

Mitosis and Meiosis are both processes of cellular division, but have some distinct differences. Mitosis is the process of cell division in which a single cell divides into two identical daughter cells with identical genetic material. Meiosis is the process of cell division in which a single cell divides into four daughter cells with half of the genetic material of the original cell.

Similarities between mitosis and meiosis include the fact that both processes result in the division of a single cell into two or four daughter cells and the daughter cells of both processes contain the same genetic material as the parent cell.

Differences between mitosis and meiosis include the number of daughter cells produced, the amount of genetic material present in each daughter cell, and the purpose of each process. Mitosis results in two daughter cells with identical genetic material, while meiosis results in four daughter cells with half the genetic material of the parent cell. The purpose of mitosis is for cell growth and replacement, while the purpose of meiosis is for producing gametes (sex cells) during reproduction.

The Result of Meiosis vs Mitosis differs in that meiosis produces four daughter cells with half of the genetic material of the parent cell, while mitosis produces two daughter cells with identical genetic material. This difference is important during reproduction because the two daughter cells created during meiosis can combine with two daughter cells from another parent to form an organism with a unique set of genetic material, while the two daughter cells created during mitosis will remain genetically identical to the parent cell.
