Producers are organisms that make their own organic nutrients (food) - usually using energy from sunlight. Green plants make their food by photosynthesis . The other organisms in a food chain are consumers, because they all get their energy by consuming other organisms.

A solid reactant is placed into a beaker of a warm water. The liquid vigorously bubbles as the solid dissolves into the solution. What will most likely happen if the temperature of the liquid is slightly reduced?
More bubbles will be produced because the solution is becoming more concentrated.
Fewer bubbles will be produced because of fewer collisions of reactant molecules.
The solid will get smaller at a faster rate because of more collisions of reactant molecules.
The solid will get larger at a slower rate because precipitate is coming out of the solution.

Note that arteries have a thicker middle layer of tissue than veins. Why is this important and how does it affect the structure of the artery as compared to the vein?

Answers

Answer:

The correct answer is - To withstand the high pressure of the outflow of blood from the Heart.

Explanation:

The heart pumps blood to different body parts at high pressure so that it can easily reach all the parts of the body quickly. To able to hold the pressure of the blood pumped at high-pressure arteries need thick walls.

This pressure can be experienced as pulse and which required the walls of arteries and the middle layer or the tunica media to make it much thicker in arteries than in veins. In veins pressure caused by blood is very low pressure that allows them to be thin walls.

explain the importance of taking named precautions before blood transfussion can be done?​

Answers

Answer:

To minimize the chance of an adverse reaction during a transfusion, health care practitioners take several precautions. Before starting the transfusion, usually a few hours or even a few days beforehand, the person is cross-matched with the donor blood (not done for transfusions of plasma or platelets).

Precautions are necessary for blood transfusion because
There are chances of getting exposed to fatal diseases like hepatitis, AIDS and many other diseases.
And avoid the reactions between antigen and antibodies, which leads to rejection of transfused blood.

Good luck

what can happen during the cycle of photosynthesis with increasing concentrations of Atrazine?

Answers

Answer:

By inhibiting photosynthesis, Atrazine kills plants. Photosynthesis, which is unique to living green plants, occurs when light energy becomes the chemical energy required for food production.

Simply stated, plants eventually die of hunger when food production stops. Atrazine selectively kills unwanted plants (weeds) competing with suitable plants for water and nutrients (crops, turfgrass). It is thus a beneficial tool for both farming and urban plants.

Explanation:

In Texas maize and grain sorghum production, Atrazine is the most often used herbicide. In several "weed and feed" preparations for domestic plowing and commercial turf-grass weed control, it is also often found as an active ingredient.

With its broad use, atrazine has been identified in minute concentrations in Texas ground and surface waterways. Because of this, it is crucial to understand atrazine behavior in the environment and the potential for harmful impacts on human and animal health and on other non-target organisms.

Describe how table salt dissolves in water in 300 words.​

Answers

Answer:

salt disloves in 300 words

Answer:

Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.

Explanation:

When sodium chloride is dissolved in water, the polar water molecules are able to work their way in between the individual ions in the lattice. The water molecules surround the negative chloride ions and positive sodium ions and pull them away into the solution. This process is called dissociation.

Why Darwin is known as father of evolution? Discuss how evidences against Darwinism led to formulation of modern evolutionary theory. Interpret its postulates in your words with relevant examples. (10 marks)

Answers

Answer:

Darwin was one of the greatest scientists who ever lived. He wrote the book 'The origin of species'. Darwin was known not only for the theory of evolution as we know it today, but also the foundation that biological sciences are based on. Darwin was very worried that people would reject his theory, so he collected a huge amount of evidence. He took evidence from the fossil record and from his own collections. He talked to animal breeders and animal collectors. He proved that the theory of evolution is based on the idea that all species are related and gradually change over time. His postulates is what gave him the title father of evolution

Postulates of evolution:-

1) Individuals within species are variable

2)Some of these variations are passed on to offspring

3)In every generation, more offspring are produced than can survive

4) The survival and reproduction of individuals are not random

The individuals who survive and go on to reproduce the most are those with the most favorable variation, and they are naturally selected.

Example:-

If an animal has to do the same task over and over again, it's body gradually changes to make the task easier. So if a deer reaches higher and higher into trees for food, day after day, it's neck will gradually stretch as it gets older.

If a deer's neck grows longer during it's lifetime, all it's babies will be born with long necks too.

Hope this helps.

Complete the sentences on the control of the cell cycle with the correct terms. After S phase ____________ appear to share a common centromere.

Answers

Answer:

After S phase sister chromatids appear to share a common centromere.

Explanation:

The cells of the different organisms go through different periods during their life, each one characteristic and well differentiated. Before the mitosis process, during the S phase of the cell cycle, the chromosomes replicate, so that at the time of initiating cell division in humans, each of the 46 replicated chromosomes will have two chromatids joined by the centromere, each one of them represents a functional chromosome. Each sister chromatid of a chromosome secretes a daughter cell, as do the other 45, and together they will make up the diploid "cluster" of 46 chromosomes from the new cell. In other words, each chromosome is made up of two chromatids that come together at a point called the centromere. One chromatid contains a condensed chromatin molecule and the other has another identical chromatin molecule, the result of DNA replication, which is why we talk about a sister chromatid chromosome. Each chromatid has two arms of equal or different length.

Genes a and b are 10 map units apart, b and c are 20 map units apart, and a and c are 30 map units apart. If a triple heterozygote is testcrossed, among 1,000 progeny, how many are expected to result from double crossovers if there is no interference?
а. 10;
b. 20;
c. can't be determined
d. 30;
e. 60;

Answers

Answer:

20 ( B )

Explanation:

Given data:

a and b are 10 map units apart

b and c are 20 map units apart

a and c = 30 map units apart

condition ; Triple heterozygote testcrossed

number of progeny = 1000

Determine the number of double crossover result

P( crossover between a and b ) = 10/100 = 0.1

P( crossover between b and c ) = 20/100 = 0.2

p( double crossover ) = 0.1 * 0.2 = 0.02

hence number of double crossovers = number of progeny * 0.02

                                                              = 1000 * 0.02 = 20

Predict what will happen to the concentration of pyruvate, NADH and H+ when the Krebs cycle is stopped by arsenic

Answers

Answer: Pyruvate would increase, NADH would decrease, and intermembrane H+ would decrease as well.

Explanation:

Glycolysis would raise pyruvate, but the Krebs Cycle would not produce NADH, decreasing it. No protons (H+) will be pushed into the intermembrane gap, lowering its H+ content and raising its pH.

What is Kreb's cycle?

The tricarboxylic acid (TCA) cycle, commonly referred to as the Krebs cycle or the citric acid cycle, is the primary route that cells use in order to acquire energy and is an essential component of aerobic respiration. The cycle transforms the oxidative potential of acetyl coenzyme A (acetyl CoA) into the reductive potential of nicotinamide adenine dinucleotide (NADH).

The synthesis of ATP via the Krebs cycle is disrupted when arsenic is present because it prevents pyruvate from being converted into acetyl coenzyme A (acetyl-CoA). In addition to the effects described above, arsenic also prevents glucose uptake at the cellular level, as well as gluconeogenesis, the oxidation of fatty acids, and additional acetyl-CoA formation.

Which of the following requires constant agonist-antagonist muscle contractions?
Core integration
Postural development
Dynamic balance
Neuromuscular strength

Answers

Answer:

Postural development

Explanation:

The agonist muscles are sets of muscles responsible for causing joint motion, whereas antagonist muscles are muscles that directly opposite agonist muscles (i.e., antagonist muscles generate an opposing joint torque to the agonist muscles). In a given movement, agonist muscles exhibit concentric contractions while antagonist muscles show eccentric contractions in order to stabilize the joint. Postural development is achieved by concerted adjustments of dorsal muscles and ventral muscles. The dorsal muscles are activated when the body sways forward and the muscle fascicles shorten. During backward sway, these muscles lengthen, while ventral muscles are primarily activated.

Dynamic balance is the condition that requires constant agonist-antagonist muscle contractions.

The agonist-antagonist muscle contraction is the movement where one muscle contracts while the other muscle is relaxing or lengthening. The muscle contracts are agonist whereas the muscle that relaxes is the antagonist here.

Core integration: In such conditions, the constant movement of muscle contraction and relaxation does not require. It is a specific movement and increased stability of the movements.Postural development: continuous development and growth of postural muscles comprising the nervous systemDynamic balance: It would be the ability to balance in motion or changing positions. In this case, muscles require constant both agonist and antagonist contractionsNeuromuscular strength: motor commands according to the central nervous system to the ability to move in the nervous system, hence it does not require constant muscle movements.

Thus, the correct answer is - Dynamic balance.
