Answer:
1. Passive ventricular fillings.
2. Ventricular ejection.
3. Atrial contraction
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The following terms describe the physical or mechanical events with the correct phases of the cardiac cycle in mammals (human beings).
1. Passive ventricular fillings: is what happens when depolarization of the atria cause the atria to go into atrial systole. Atrial pressure increases and more blood is forced into the ventricles via the AV valves.
2. Ventricular ejection: is the continued contraction of the ventricles that leads to the pressure inside the ventricles to build up and will thus force open the semilunar valves and blood will be ejected out of the heart to the pulmonary and systemic circuits.
3. Atrial contraction: the process that begins when both the atria and the ventricles are in diastole. Blood from the veins are returning to the heart and the pressure within the atria is higher than the ventricular pressure. Causing the AV valves to open and blood will passively fill into the ventricles. It is important to know that the semilunar valves are closed shut because they have higher pressure than both the left and right ventricle.

Radiant energy is converted into chemical energy, and this is a light-independent stage.
Sugar molecules like glucose are formed, and this is a light-dependent stage
The final products of fotosynthesis are carbohydrates, ATP, NADPH, and oxygen is released. During the firt stage of photosynthesis, radiant energy is converted into chemical energy, and this is a light-dependent stage.
Stages of Photosynthesis
Photosynthesis involves two stages: light-dependent and light-independent reactions.
During light-dependent reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions.Light-independent reaction is known as the Calvin cycle, and it takes place in the stroma. Sugars or carbohydrates are synthesizedLight-Dependent reaction
Chlorophyll molecule in Photosystem II captures luminous energy from the sun. The pigments absorb light, exciting the electrons, which get in a higher energy level. Excited electrons leave photosystem II and move to photosystem I along the electron transport chain. When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. Photosystem I absorbs more luminous energy that drives the electrons to another electron acceptor, from where they get transported again and used to produce NADPH molecules. When electrons are sent from Photosystem I, they are replaced by new electrons coming from photosystem II through the transport chain. As electrons go through the transport chain, their released energy is used to produce ATP molecules.

In order to measure the absorption spectrum of CoCl2, you need to dilute the stock solution to 0.32 M. What volume of the stock solution (0.8 M concentration) and water should be mixed to make a 10 mL solution of 0.32 M?
Explanation:
Volume of stock solution needed
= 10mL * (0.32M/0.8M)
= 10mL * (4/10) = 4mL.
Volume of water needed
= 10mL - Volume of stock solution
= 10mL - 4mL = 6mL.
The volume of water needed in this case will be equal to 6 ml.
What is the stock solution?To make a stock solution, weigh out the proper amount of a pure solid or measure out the proper amount of a pure liquid, put it in the right flask, and then dilute it to the desired volume. Depending on the intended concentration unit, many methods can be used to measure the reagent.
For instance, to make a solution with specified molarity, you weigh out the proper mass of the reagent, mix it with some solvent, and then add enough liquid to make the necessary volume. You measure out the right amount of solute and add enough solvent to get the right total volume to create a solution where the solute concentration is expressed as a volume percent.
A highly concentrated stock solution is frequently diluted to create solutions. The stock solution is moved to a new vessel and produced to a new volume at a known volume.
Here,
The volume of stock solution needed
= 10mL × (0.32M/0.8M)
= 10mL × (4/10) = 4mL.
The volume of water needed
= 10mL - Volume of stock solution
= 10mL - 4mL = 6mL.
Therefore the volume of water needed here is equal to 6 ml.

Answer:
It is all of them and I have PROOF
Explanation:
HERE IT IS YOU CHEETERS, isn't brainly the best?
In cats, the X-linked genes determine the fur color. The alleles for the fur color are present on the same locus but can have a different version, such as a cat can produce orange or black fur color.
The combinations of fur possible are:
Black
Black and White
Black, Orange, and White
Orange
Orange and White
The X-linked gene is responsible for the color or tortoiseshell of the cats.
The black color in the cats is caused due to the pheomelanin and the black color is caused due to eumelanin. The condition arises because of the inactivation of the X-chromosome.
For instance, the heterozygous patches of orange and black tortoiseshell result in the expression of different alleles coding for different fur colors.
Thus, in the female cats, the genotype is two X-chromosomes, which can result in all the possible tortoiseshells.

How do the nutrients found in plants function in plant DNA? Is the function of plant DNA similar to human DNA?
Answer:
How do the nutrients found in plants function in plant DNA?
Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
Is the function of plant DNA similar to human DNA?
How much DNA do plants share with humans? Over 99%? ALL animals and plants share the same DNA which is basically a code of only 4 'letters' which code for the same amino acids from which all proteins are made.

how a decreased number of locusts would affect other organisms
which species might eat the crops in the absence of locusts
how the disease can be used for other applications
O how quickly farmers would get to see the results
Answer: how a decreased number of locusts would affect other organisms.
Explanation:
When engaging in any action aimed at destroying large numbers of an organism as is the case here, there is always a need to check what impact it might have on the ecosystem at large.
This is why it is very important that the effect of a decreased number of locusts on other organisms is evaluated before such drastic action is taken. If it would lead to a situation where the ecosystem is destabilized, the consequences would be far reaching and very damaging.
How a decreased number of locusts would affect other organisms is the
most important to find out before producing the disease.
