Answer: The question is incomplete and the options are not given but here are the options gotten from another websites.

A. Narrow part.

B. Wide part

C. The flow rate are the same in both part.

The correct option is C.

The flow rate are the same in both part.

Explanation:

The flow rate are the same in both because when there is partial blockage at the artery wall, the blood flow speed will reduce or stop, therefore the blockage will be a barrier or hindrance to free blood flow and therefore, both the narrow part and wide part will receive the same level of blood flow because of the blockage and this blockage result in restricted blood flow which in one way or the other hinder oxygen supply to the heart. The blockage deposits can cause a thickened artery wall and when blood flow is restricted it causes chest pain and if it stop it can cause heart attack. Blockage deposits can be as a result of artery wall damage.

Answer:

Every organism needs nutrients to build tissues and carry out life functions. Like water, nutrients pass through organisms and the environment through biogeochemical cycles. ... If ample sunlight and water are available, the primary productivity of an ecosystem may be limited by the availability of nutrients.

Explanation:

Nutrient availability is directly proportional to primary productivity.

In an ecosystem, the plants are the primary producers. They are able to trap energy directly from the sun and use it combine water and carbon dioxide in the presence of nutrients.

These nutrients are particularly important in the functioning of these primary producers. The more the available nutrients, the higher the primary productivity in an ecosystem and vice versa.

Hence, there is a direct relationship between nutrient availability relate to the primary productivity of an ecosystem.

Answer:

Because sound waves can also create energy.....waves also create energy so it's considered because it can be used in machines

Explanation:

✌❤❤✌

The sound waves are considered a type of mechanical energy as sound waves transfer energy by the motion of particles. The correct option is C.

Mechanical energy (kinetic energy or potential energy) is the energy of a moving object or the energy stored in objects due to their position.

Mechanical energy is another source of renewable energy. Many types of renewable energy rely on mechanical energy to generate or convert energy.

An object's mechanical energy can be the result of its motion (i.e., kinetic energy) or its stored energy of position (i.e., potential energy).

The sum of potential and kinetic energy equals the total amount of mechanical energy.

Sound waves are a type of mechanical energy because they transfer energy through particle motion.

Thus, the correct option is C.

Answer:

4. According to what is observed in the diagram, the maltose (substrate) binds to the maltase (enzyme) to obtain glucose molecules (product), in a process of hydrolysis of the maltose.

5. Three factors that can affect intestinal maltose activity - slowing it down or stopping it - are temperature, pH and substrate depletion.

Explanation:

4. Enzymes, such as maltase, have the function of making a reaction faster and decreasing the activation energy. Maltase is responsible for breaking down a maltose molecule, a dimer, into two glucose monomers, which is a hydrolysis reaction of the bonds that hold glucose molecules together.

5. There are several factors that can cause the decrease or cessation of the activity of an enzyme. Enzymes are activated when substrate is available and work best under ideal temperature and pH conditions. When there are alterations of these factors, the enzyme will reduce or stop the reaction in which it intervenes.

Answer:

1. Chloroplast

2. 38 molecules of ATP

3. orange-red and violet-blue

4. There are half as many chromosomes in egg cells.

Explanation:

1. According to the image 1 in this question, the process of PHOTOSYNTHESIS is being described. Photosynthesis is the process whereby plant cells synthesize their food (sugar) in the presence of sunlight. CO2 and water are used as reactants, while O2 gas is released as shown in the image as gas bubbles. This unique process of photosynthesis occurs in the CHLOROPLAST organelle.

2. Cellular respiration is the way through which living organisms obtain usable energy for metabolic activities. It is the process of breaking down food substances in a series of steps. Cellular respiration occurs in three major stages viz: glycolysis, Krebs cycle and oxidative phosphorylation. Glycolysis produces pyruvate, which may enter the mitochondria for the next stages in the presence of oxygen to yield 38 molecules of ATP.

3. Image 2 shows the absorption spectrum of chlorophyll pigment. As depicted in the image, the highest absorption spectrum of the photosynthetic pigment is at the "orange-red and violet-blue" wavelength. This connotes that the energy used in photosynthesis is most likely obtained from those regions of the spectrum.

4. Meiosis is the process through which gametes are formed. In the process of meiosis, each of the gametes will contain half of the chromosome number as the parent cell. This means that the egg cell (female gamete) produced by a female will contain half as many chromosomes than the somatic or body cell that undergoes the division.

Cellular respiration is the process through which food is broken down to yield energy. It takes place in every living entity.

The correct answers are:

1. Chloroplast

2. 38 molecules of ATP

3. orange-red and violet-blue

4. There are half as many chromosomes in egg cells.

The reasons for the following are:

1. In the first image, photosynthesis is shown. It is the process of producing food in the presence of light and carbon dioxide to give out oxygen. Carbon dioxide and water are reactants, which in the presence of sunlight react and yield oxygen as a byproduct. In the image, the oxygen is given out as bubbles.

2. Cellular respiration is the process occurring in every living organism. It is a process through which organisms obtain energy by breaking down food substances. Cellular respiration involves glycolysis, Kreb's cycle, and oxidative phosphorylation to yield energy in the form of ATP.

3. Image 2 represents the absorption spectra of the chlorophyll pigment. The photosynthetic pigment has the highest absorbance at the orange-red and violet-blue wavelength. This explains that energy required to carry out photosynthesis is obtained from this region of light.

4. Meiosis is a reduction division, in which the number of chromosomes is halved from the parent to daughter cells. The parental gametes consist of half the number of chromosomes, which then fuse to form a diploid zygote. The somatic cells undergo mitotic division, in which the number of chromosomes in the parent cells is similar to the daughter cells.

Answer:

Please find the explanation to this question below

Explanation:

The ATP cycle is the series of reactions involving glycolysis, Krebs cycle and oxidative phosphorylation that produces/synthesizes ATP in living cells. These processes collectively is called CELLULAR RESPIRATION. Glycolysis produces 2ATP molecules, Krebs cycle produces 2ATP while the electron transport chain (oxidative phosphorylation) produces 34ATP molecules.

This cycle of ATP as explained above is an important frequent event in cells because all organisms need energy to carry out their metabolic activities. ATP is the energy-carrying molecule that stores and releases energy for use by the cells, hence, it needs to be produced on a frequent basis.

ATP can be likened to a charged battery ready to release its stored energy. The energy is stored in the phosphate bonds that makes up its structure. When ATP releases its energy, it becomes ADP (Adenosine diphosphate). However, ADP is a reactant in the ATP cycle, which is phosphorylated with an inorganic phosphate (Pi) and catalyzes by ATP synthase to form ATP.

Explanation:

during fertilisation the sperms are drawn up by a suction through the cervix into the uterus where they swim upto the oviduct using their tails although the sperms are millions only one will fertilise the ovum. as the ovum moves down the oviduct, it releases chemical substances which have to be neutralised by those produced by the acrosome before the sperm penetrates the ovum. when the sperm comes into contact with the egg the acrosome bursts open and releases the lytic enzymes which dissolve the egg membranes. Then the acrosome then turns inside out forming a fine filament that is used to penetrate the egg. Hence the head of the sperm enters the ovum, the tail is left outside the egg. the vitelline membrane undergoes a change which stops any other sperm from entering the ovum. once in the cytoplasm the head bursts to release the male nucleus then fuses with the female nucleus to form a diploid zygote

The Major functions of connective tissue include: 1) binding and supporting, 2) protecting, 3) insulating, 4) storing reserve fuel, and 5) transporting substances within the body.

All other types of tissues in the body are supported by connective tissue, which joins or divides them. Like all tissue types, it is made up of cells encased in a space of liquid known as the extracellular matrix (ECM).

In contrast to other forms, connective tissue's cells are loosely rather than densely packed within the ECM.

The three components of connective tissue are cells, ground substance and fibers. Ground substance and fibers make up the extracellular matrix (ECM).

The primary cell of connective tissue is the fibroblast. Its function is to produce and maintain the ECM of connective tissue. Besides fibroblasts, several other cell types are present.
