Type your response in the box. Many countries have laws that regulate hunting, including restricting hunting to specific times of year. Why is this hunting restriction important for preserving certain animal populations?

Answers

Answer:

You can only hunt dear (example) for only sertin times of the year because when the doe's have their fans people want them to get big before they shoot them

Answer:

Animal populations can change from one season to another, so it’s important to restrict hunting to seasons when the population is high. Such a restriction helps prevent a severe drop in population, which could threaten the species. It’s also important to limit hunting during breeding seasons to increase the possibility of offspring reaching adulthood.

True or False: Within the body, all atoms combine to form molecules. If false, why?

Answers

Answer:

True

Explanation:

Two or more atoms combine to form a molecule, like how the water molecules, proteins, and sugars are found in living things.

Hope this helps! (づ ̄3 ̄)づ╭❤~

The statement i.e. ''Within the body, all atoms combine to form molecules'' is true.

Atoms combine together to form molecules because atom is unstable substance which can't stay in single form due to its reactive nature but become stable when they form molecules due to filling of outermost shell and attain the electronic configuration of noble gases so we can say that atoms formed molecules in order to attain stability and can not remain individually.

Animal cell  is smaller than ribosome of plant cell

Explanation:

In part A, you analyzed genes that contribute to two diseases. (cystic fibrosis and muscular dystrophy) How can scientists use this information to develop new treatments for these diseases? Based on your findings, do you think that scientists will need to develop multiple treatments to control symptoms of these diseases? Explain your reasoning.

Answers

Answer:

By designing suitable gene therapies in order to restore target gene expression.

Explanation:

Cystic fibrosis and muscular dystrophy are inherited genetic disorders associated with serious health problems. Cystic fibrosis is caused by mutations in the gene that encodes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein, and it is a condition associated with abnormal production of sticky mucus that leads to problems in the lungs and the digestive systems. On the other hand, muscular dystrophy is produced by mutations in genes localized on the X chromosome such as, for example, the gene 'dystrophin'. Gene therapy is an experimental approach used to compensate abnormal gene function by introducing exogenous genetic material and thus restore their altered protein products. Consequently, personalized gene therapies can be useful to treat inherited disorders such as cystic fibrosis and muscular dystrophy.

When CFCs are exposed to high levels of UV radiation, what occurs? A. The compound breaks down into nitric oxide and ozone. B. All of these C. A chlorine breaks off and forms a free radical. D. They become ionized and stick together in clumps that become part of smog.

Answers

Answer:

C. A chlorine breaks off and forms a free radical

Explanation:

When CFCs are exposed to high levels of UV radiation in the atmosphere, the CFC molecule breaks into chlorine and forms free radicals.

These free chlorine radicals then reacts with ozone molecules and breaks the ozone atom (O3) to form chlorine monoxide and oxygen (O2) molecule.

CFCs are main cause of ozone depletion in the atmosphere.

Hence, the correct option is "C".

21.
A bean plant produces seeds in long pods.
22.

23.

Answers

Answer:

New leaves appear on a tree in spring. - NO

An amoeba divides in half. - YES

A bean plant produces seeds in long pods. - YES

Pollen grains are released from a flower. - YES

A sea star produces a new arm after losing one to a predator.​ - NO

Explanation:

The appearance of new leaves has nothing to do with reproduction but rather regeneration.

An amoeba dividing in half is a form of reproduction known as asexual. Binary fission is a reproductive process in which an organism divides into two and each half develops into new independent organisms.

A bean plant producing seed is part of the reproductive process. After fertilization, the ovule of a flower becomes the seed. A seed in itself is a ripened fertilized ovule.

The release of pollen grains from the anther of a flower to the stigma of a compatible flower in the same or different individuals plants is known as pollination. Pollination is a reproductive process similar to fertilization.

A sea star producing a new arm after losing one to a predator is a regeneration process rather than a reproductive process.

Which of the following is NOT true of enzyme activity? a. enzyme shape may change during catalysis b. the active site on an enzyme orients its substrate molecules, therby promoting interaction of their reactive parts c. all enzymes have an active site where substrates are temporarily bound d. each enzyme can catalyze a wide variety of different reactions

Answers

Answer:

D. Each enzyme can catalyze a wide variety of different reactions

Explanation:

Each enzyme can only catalyze a few, specific types of reactions.

Since enzymes and substrates are very specific to one another, enzymes cannot catalyze a wide variety of reactions.

If a substrate is not the correct one that fits in the enzyme's active site, a reaction will not occur.

So, each enzyme can only assist in a few reactions.

The correct answer is D. Each enzyme can catalyze a wide variety of different reactions

Humans use science as a systematic approach to understanding the natural world. Its goal is to eliminate prejudice by using facts and observations to identify and describe underlying concepts and mechanisms. Pseudoscience lacks scientific rigor and relies on unproven claims driven by prejudices or beliefs, resulting in misunderstandings.

The basis of real science is actual data collected by experiment, observation, and application of the scientific process. Myths are important cultural myths that may not reflect scientific reality. While myths have their roots in tradition, they should not be confused with facts verified by science.

The following events are part of a negative-feedback mechanism. I. blood pressure increase II. receptors detect a low blood pressure III. control center compares actual pressure with the set point IV. the heart beats faster Choose the arrangement that lists the event in the order they occur.

Answers

Answer:

II, III, IV, I

Explanation:

Blood pressure regulation is an example of negative feedback mechanism. When the blood pressure is low, sensor in the blood vessels called baroreceptors detect this and send a signal to the control center which is the hypothalamus.

The hypothalamus compares the current blood pressure with the normal and proceeds to send signals to the heart, as well as blood vessels and kidneys. The heart begins to beat faster, thereby increasing the heart rate and a a result, blood pressure goes back up to normal.

What are change of state?

A state is physical condition of any substances it means that any substance which found on earth are mainly found in three states and these are following:-

1- Solid

2- Liquid

3- Gas

A change of state is physical change of state i.e any substance which changes their state from ( solid to liquid called melting), (liquid to gas called evaporation), (gas to solid called diffusion) etc  are called change of state.

These change of state occurs when temperatures or pressure changes in a system or substances. When the temperature or pressure increase  the interaction between the molecules also increases.

Therefore,the best interpretation of the two flat portions of the graph where these shows that change of state are occurring. Thus, C is correct option.

somatosensory cortex.

Explanation:

Hope it helps you.....

Thank you..

Somatosensory cortex area of the brain receives information collected from mechanoreceptors. Option D is correct.

The somatosensory cortex is a region of the brain that receives information collected from mechanoreceptors. Mechanoreceptors are sensory receptors that respond to mechanical stimuli, such as touch, pressure, and vibration. The somatosensory cortex is located in the parietal lobe of the brain, and it is divided into two parts: the primary somatosensory cortex and the secondary somatosensory cortex.

The primary somatosensory cortex receives information from the skin, muscles, and joints. The secondary somatosensory cortex integrates this information and allows us to perceive the location, intensity, and quality of touch. The pons is a region of the brainstem that is involved in the coordination of movement and the regulation of sleep. The olfactory lobe is a region of the brain that is involved in the sense of smell. The medulla is a region of the brainstem that is involved in the control of breathing, heart rate, and blood pressure. Option D is correct.
