Why must dioecious organisms find mates in order to reproduce?

The energy would move from the phytoplankton to the zooplanktons all the way up to the musky.

Energy is moved through a food web or food chain in an aquatic ecosystem. Producers at the base of the food chain, like phytoplankton and aquatic plants, use photosynthesis to convert solar energy into organic matter.

The energy is then transferred to the secondary consumers, which include larger fish and predatory invertebrates, who eat the primary consumers. Tertiary consumers, such as apex predators like sharks or killer whales, and so forth, eat secondary consumers.

Answer:

In a flower, this landing zone and entrance is the stigma. It plays a pivotal role in reproduction. Most stigmas are adapted to trap pollen with hairs, flaps and other surfaces to increase their efficiency. Most stigmas are covered with a waxy, sticky substance.

Answer:

Respiration -the action of breathing.

The process that can only be carried out byplants in the presence of light-dependent reactions. These reactions convert light energy to chemical energy and is present in the process of photosynthesis. The energy from the sun together with water is being broken down to give rise to ATP and NADPH which are used in light-independent reaction or dark reactions.

Cellular respiration does not use light since it is not dependent on light. Dark reactions are light-independent processes. Homeostasis is the maintenance of the internal environmentr of an organism in order to survive.

Answer - B light-dependent reactions

All the given amino acids listed below will predominantly as a molecule with both positive and negative charges at pH of 8.0

At a pH of 8, all the molecules as unfastened amino acids could have at the least one advantageous and one poor price, because the carboxylic acid could have a -1 price and the amino terminus could have a +1 price. According to the given table, arginine and glutamic acid may even have charged facet chains. Free amino acids include at the very least  companies which could come to be charged. The first is the carboxylic acid terminal, which exists as neutral -COOH whilst protonated and negatively-charged -COO− whilst deprotonated. The 2d is the amino terminal, which turns into the positively-charged -NH3+ whilst protonated and the neutral -NH2 whilst deprotonated. Note that "protonated" isn't constantly synonymous with "advantageous." A protonated role may be both advantageous or neutral, relying at the institution in question. Similarly, a deprotonated role may be both poor or neutral. Low pH --> Protonation (COOH) and High pH --> deprotonation (COO-)

Explanation:

The ATP/CP Pathway is best for in 100m sprint activity.

Adenosine Triphosphate (ATP) is the energy carrier in every living organisms on earth which capture and store energy metabolized from food and light sources in the form of ATP.

ATP is broken down through hydrolysis during energy required by a cell, The high energy bond is broken and removal of a phosphoryl group occurred.

The energy released from this process is used to drive various cellular processes.

the following statements about good experiments is TRUE

A good experiment should have at least two groups: one control group and one experimental group.

An experimental group is a group of subjects in an experiment that is exposed to a manipulation of an independent variable, also known as a treatment. The experimental group is used as a point of comparison to a control group, which is not exposed to the manipulation of the independent variable. The goal of the experimental group is to determine whether the manipulation of the independent variable has an effect on the dependent variable, which is the outcome being measured. The experimental group allows researchers to establish cause-and-effect relationships between the independent and dependent variables, as the manipulation of the independent variable can be linked to changes in the dependent variable. The experimental group is an essential aspect of experimental design in scientific research, as it allows researchers to test hypotheses, evaluate theories, and draw conclusions about the phenomenon being studied.

A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.

Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.

The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.

Your question is a bit confusing.

As per the image figure the corals live in calcium deposits and they have a hard exoskeleton. After the death of the organisms, the skin will remain the same.

The corals are marine invertebrate species that live in colonies and feed on lime they develop in coral polyps and represent a sac-like animal.

They have an exoskeleton that remains after they die. They, can soft, stay, and spongy corals. A coral skeleton is a mineral plus organic matter.

The coral species harden from the outside while they are alive from inside like the roots of plants. Shows signs of evolution and life.

Power is defined as the amount of work done per unit time or the transfer of energy.

For the calculation of power, formulae are

\(P = \frac{W}{t}\)

\(PE = mgh\)

where

P = Power in Watts (W) or Joules/sec (J/s) or N.m/s

W = Work in Joules (J) or Newton-meter (N.m)

t = time in seconds (s)

PE = gravitational potential energy in Joules (J) or Newton-meter (N.m)

m = mass in kilogram (kg)

h =  height in metres (m)

Given:

w = 200 N

h = 6 m

t = 8 s

Calculation:

PE = 200×6

PE = 1200 J

P = W/t

Lower than normal blood pressure will cause which of the following effects on the rate of clearance of substance A is C. A decrease, because a decrease in the rate of urine output will allow more reabsorption by the kidneys

Kidneys are bean-shaped organs located behind the abdomen which function as excretory organs and play a role in blood control. The kidneys control blood pressure through regulation of extracellular fluid volume and renin secretion. Blood pressure can be caused by a lack of fluid which causes blood volume to decrease, causing a decrease in blood pressure.

Decreased kidney function is characterized by a decreased glomerular filtration rate based on measurements of creatinine clearance, caused by low blood pressure thereby reducing the filtration rate of the glomerulus. This causes the amount of substance A to decrease in the urine due to reabsorption by the kidneys.

Answer:

If a vial of morphine has 10 mg/mL, and a dose of 4 mg is required to be administered intravenously, 04 mL must be administered to fulfill the indication.

Explanation:

Morphine is a drug, an opioid derivative, with a potent analgesic and sedative effect. Its use is intended for acute or chronic severe pain, mainly related to cardiovascular disease, cancer or severe trauma.

One vial of morphine vial has a concentration of 10 mg/mL, so if 4 mg is required, a simple calculation must be made:

Morphine: 10 mg ------------ 1 mL

Dose:          4 mg ------------ X

X = (4 x 1)/ 10

X = 4/10

X = 0.4 mL

To administer 4 mg of intravenous morphine, 0.4 mL of the injection should be used.
