.Answer: conduction or polarization

Answer:

conduction, friction

Explanation:

Friciton: When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged.

Conduction: During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod.

Answer:

Cellulose - It is described as a complex carbohydrate that forms the main constituent of the cell wall in most plants and is important in the manufacture of numerous products like pharmaceuticals, textiles, etc.

Chlorophyll - Any of a group of green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria.

Chloroplast - An organelle found in the cells of green plants and in photosynthetic algae, where photosynthesis takes place.  

Bryophyte - Any plant of the division Bryophyta, defined "sensu lato" to comprise the mosses, liverworts, and hornworts, and corresponding to all embryophytes that are not vascular plants.

Pterophyte - It is characterized as any fern(seedless plant) that is a division of Pteridophyta.

Gymnosperm - Any plant such as a conifer whose seeds are not enclosed in an ovary or those who don't bear seeds or fruits. Example; Cycads.

Cone - A cone-shaped flower head of various plants like banksias and proteas.

Angiosperm - Any flowering plant characterized by having ovules enclosed in an ovary and thus, produces fruits, as well as, seeds.

Flower - A reproductive structure in angiosperms and often conspicuously colorful and typically including sepals, petals, and either or both stamens and/or a pistil.

Cuticle - A noncellular protective covering outside the many invertebrates and plants.

Vascular tissue - The complex tissues that consist of various cell types and primarily responsible for transporting liquid and other nutrients throughout the plant or animal body.

Xylem - A vascular tissue in the land plants primarily responsible for the distribution of water and minerals that are taken up by the roots and also the key component of the wood.

Phloem - A vascular tissue in land plants primarily responsible for the distribution of sugars and the nutrients manufactured in the shoot.

Roots - The part of the plant which is generally underground that anchors and supports the plant body. It absorbs and stores water and nutrients, and in some plants is able to perform vegetative propagation.

Root hairs - The rhizoid of a vascular plant or a tabular outgrowth of a trichoblast, hair-forming cell on the epidermis of a plant root.

Stems - The above-ground stalk of a vascular plant that supports individual parts of a plant like leaves, flower, fruits, etc.

Leaves - The green and flat organ that represents the most prominent feature of the most vegetative plants.

Photosynthesis - The process by which plants and other photoautotrophs convert light energy into chemical energy. For example; Plants use air, water, along with sunlight to synthesize their food(carbohydrates and waste oxygen).

Answer: Its wider and thicker than most blood vessels

Answer: The aorta is the largest blood vessel in the body. This artery is responsible for transporting oxygen rich blood from your heart to the rest of your body. The aorta begins at the left ventricle of the heart, extending upward into the chest to form an arch.

Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.

Explanation:

Answer:

All cells in the body need to have oxygen and nutrients, and they need their wastes removed. These are the main roles of the circulatory system. The heart, blood and blood vessels work together to service the cells of the body.

It's correct

Answer:

Explanation:

It ensures that information travels in one direction only.

It is the gap between neurons.

Plants:

1. Most plants respond to the environment by growing towards the light.

2. Plants respond to daily and seasonal cycles and diseases.

Flatworms:

1. Flatworms respond to changes in light.

2. Flatworms adapt to marine life by using diffusion to breathe and to distribute nutrients to other parts of the body.

Humans:

1. The nervous system allows an organism to respond quickly to changes in the internal or external environment.

2. Some humans modify the environment (positively or negatively), such as cutting forests, building dams, and expanding urban areas, etc.

Answer:

✦ The birth and death rates will balance each other out for a net growth rate of zero.

✦ Death rate will increase, and birth rate will decrease until they balance each other out.

✦ The population will no longer grow in size.

Explanation:

Due to practical limitations of food, water, and space, a given environment has a maximum population size it can support.

Answer:

The beef bone marrow was denser than the chicken bone because it had more mass in the given volume. Since the chicken must fly, it cannot have its bones weighing it down on the land. However, cows must find grass on land and travel long distances. This would increase the overall density of the bone.

menstration period is when a woman's body releases tissue it no longer needs so then the girl bleeds (usually for 7 days) and then every month or so (different for all girls) the uterus lining gets thicker to prepare for a fertilized egg if the woman becomes pregnant. :)

Answer:

the blood would stop pumping, because the blockage allows the blood to move one way, but when there is not blockage, the blood would enter from both ways making it impossible to regulate

Answer:

meiosis produced gametes

Explanation:

During sexual reproduction, meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.

The Paleozoic Era began approximately 550 million years ago and ended approximately 252 million years ago.

The Paleozoic Era is a geological epoch that lasted about 541 million years and ended about 252 million years ago.

It is also known as the "Age of Invertebrates" because it witnessed the rise and dominance of numerous invertebrate groups, including trilobites, brachiopods, and ammonites.

From oldest to youngest, the Paleozoic Era is divided into six periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.

Many significant events in the evolution of life on Earth occurred during this time period, including the Cambrian period's explosion of diversity, plant and animal colonization of land, and the emergence of reptiles and insects.

Thus, the answer is 550 million years ago.

Answer:

C .

Explanation:

Answer:

The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you're less aware of — like the beating of your heart and the digestion of your food.

Think of the brain as a central computer that controls all the body's functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.

Explanation:

If you brain does not, or is unable to perform multiple tasks automatically, you could have trouble breathing on your own, your heart could have problems, even your thought process, movement, and digestion could malfunction. Which could cause a multitude of complications.

Explanation:

The statement that is best supported by the image is that species T and species U are related to species X.

Is the gradual development of new forms of organisms from their ancestral forms.

In the image, X is the ancestor of T, U, V, and S. Thus T, U, V, and S are related by common ancestry.

Thus, it is correct to say that T and U are related to species X.

However, it is incorrect to say that X evolved later or species U and V evolved from S.

Answer:

the population of rabbits might increase

Explanation:

With less predators to eat them, the rabbit population will likely go up if the fox population decreases; assuming there are favorable factors such as plenty of food and habitat for the rabbits. At some point, there is a maximum limit to the number of rabbits that a certain location can hold. Once this limit is reached, (some of) the rabbits will migrate elsewhere or unfortunately die off.

As the rabbit population increases, the fox population may rebound and start increasing again. This is due to more food being available to the smaller amount of foxes, and there is less competition for food. So the rebounding fox population will likely bring down the rabbit population to a point where food will get more scarce for the foxes. This cycle repeats itself where one population increases while the other decreases, and vice versa. They are very strongly linked together. It's also possible that both will increase together if environmental factors are favorable, but they could easily decrease together if a habitat is being destroyed for instance. It will depend on the circumstance.
