The contraction will increase. The first option is the correct option.
What is the contractile vacuole?It is an organ that helps to excrete excess water from the body of some protozoans such as paramecium.
The more excess water present in the organism, the more the contractile vacuole contracts to get rid of the water.
With distilled water, more water will enter the cell and this excess water will need to be gotten rid of. Thus, the contraction rate will increase.

2. Why is an amniotic egg an evolutionary leap for reptiles? 1It allowed animals to move away from water as a requirement for reproduction and become completely terrestrial. 2 It allowed for many offspring to be made at the same time. 3 It allowed female reptiles to lay their eggs and leave the young to fend for themselves. 4It allowed for asexual reproduction by females only.
It allowed animals to move away from water as a requirement for reproduction and become completely terrestrial. Option 1.
Evolutionary advantage of the amniotic eggThe amniotic egg enables organisms to live their lives entirely away from water.
Prior to the evolution of the amniotic egg, the egg being laid by animals cannot survive on land. Also, the fertilization of the eggs requires water.
The amniotic egg is equipped with features that enable it to survive conditions on land. The external shell and the amniotic fluid protect the embryo from mechanical damage and dehydration. Gaseous exchange and waste excretion of the embryo are taken care of by the allantois and the chorion.

Describe the role of the hypothalamus and the adrenal glands in bringing about changes in the blood vessels in the human skin and explain why these changes occur.
The role of the hypothalamus and the adrenal glands is The hypothalamus stimulates corticotropin-releasing hormone (CRH) that stimulates the pituitary gland to perspire adrenocorticotropin hormone (ACTH). ACTH then prompts the adrenal glands to make and release cortisol hormones into the blood.
What are the responsibilities of the adrenal glands?Adrenal glands are endocrine glands found on top of your kidneys. They produce many essential hormones, including cortisol, aldosterone and adrenaline. The adrenal hormones help control several bodily functions including metabolism, blood pressure and your body's reaction to stress.

What do we call Earth's orbit around the Sun?
intergalactic movement
Earth's revolution
Earth's rotation
galactic movement
Answer:
Earth's revolution
How do we know that the earth orbits the sun?If you study the stars and know where all the planets on the solar system are, you will notice that those stars alternate their motion in the sky, which means they do not orbit the Earth. In fact, the word "planet" originally means tricky star, suggesting that those "stars" did not behave like other normal stars.
The theory of universal gravity cannot be denied, since we are able to send satellites to outer space and have them orbit our plant. In fact, we are able to derive equations to figure out how fast the satellite need to orbit around the earth in relation to how high above the surface of the earth it is. The same mathematics that derived said information had also been used to derive the geosynchronous height from the Earth, which is the height at which a satellite orbiting the Earth, with the necessary speed to stay in circular orbit (not elliptical orbit), matches the Earth's rotation about its axis. Geosynchronous satellites are used for T.V. broadcasting and many other applications.
The formula for universal gravitation is GMm/r2, which means that the force of gravity on an object by another object are proportional to the masses of both objects, and inversely proportional to the square of the distance between them, and this proportion is multiplied by a constant G. It makes greater sense that the Earth revolves around the Sun, and not the other way around, because the mass of the Earth is way too small to apply a force strong enough to create a large enough acceleration on the sun to keep it in orbit around the Earth. If the Earth had enough mass to cause that huge of a gravitational force, then the moon will not remain in orbit around the Earth, but will fall closer the Earth and hit the Earth.
What is the revolution of a planet?The process through which a planet, let's say the earth, revolves around a huge mass that is significantly larger than the planet, such as the sun or any star. And the gravity between the two bodies is what causes this process to occur.

3 Describe two pieces of evidence that show that plants cannot make their own food without light.
4 Starch tests show where photosynthesis has taken place. What can you conclude using the evidence from test 1?.
à5 What does the evidence from test 3 show?
1. Animals depend on plants to keep them alive is Plants are producers they take energy from the sun, nutrients from the earth, and water to grow and have their flowers, seeds, and berries.
They also release oxygen, which all animals, including humans, need to stay. Animals are consumers and they all depend on plants for survival.
2. carbon dioxide and water reach the chloroplasts in leaves is Basically the roots consume the water and transports it up the xylem, which gets it to the leaves. Carbon dioxide contacts the chloroplasts in the leaves via a stomata
3. Two pieces of evidence that show that plants cannot make their own food without light. When plants lack light, they don't deliver chlorophyll (the green pigment in plants), and plants can turn pale green to yellow to white. Plant stems become “leggy,” meaning stems become long and thin and appear to be advancing toward the source of light.
The photosynthesis is the only method for synthesizing food. It is commonly believed that about 717.6Kcal energy is required to prepare just 10g of glucose. No energy input no metabolism and therefore no food.How are leaves tested for starch?The existence of starch in leaves can be tested by the Iodine test.

Explanation: The phloem tissue of a plant is one of the vascular tissues of higher plants responsible for the conduction or transportation of photo-synthetically manufactured food (usually in the form of sugar) round the body of the plant to the various tissues and organs that require it.
The tissue moves food materials from their source of manufacture, usually the leaf, to other parts of the plant. Hence, in order to extract the syrup from the maple tree, the phloem layer must be tapped into.

Alcohol can boost GABA activity in the brain in one of two ways: either by acting on the presynaptic cell, which increases GABA release, or. It can influence the postsynaptic (i.e., signal-receiving) neuron, promoting the GABAA receptor's activation.
The brain circuits that regulate motivational processes, such as arousal, reward, and stress, are altered by chronic alcohol consumption. These modifications impact systems that use dopamine, opioid peptides, -aminobutyric acid, glutamate, and serotonin as signaling molecules as well as systems that control the brain's stress response.

The rate of cellular respiration and photosynthesis can increase or decrease because of different factors.
Explain how either the rate of cellular respiration or the rate of photosynthesis can be increased and decreased. Be sure to include details of specific reactions in your answer.
The main environmental factors that affect photosynthesis are: light, CO2 and temperature. Also, the availability of water and nutrients are important factors.
How to increase the rate of photosynthesis?Plants kept under ideal conditions of luminosity and carbon dioxide concentration increase the rate of photosynthesis as the ambient temperature increases, up to close to 40°C. Above this temperature limit, there will be a drastic reduction not only in photosynthesis, but also in most vital reactions.
The photosynthetic rate, that is, the intensity of photosynthesis that the plant performs, can be changed by the amount of light it receives. The greater this light radiation, the greater the photosynthetic rate, if there is no other factor such as temperature or water availability limiting the process.
