Blood is a tissue because it is made up of different types of specialized cells.
Aside from red and white cells, what else does blood contain?
Answer:
Plasma is the liquid portion of the blood. Blood cells like red blood cells float in the plasma. Also dissolved in the plasma are electrolytes, nutrients and vitamins (absorbed from the intestines or produced by the body), hormones, clotting factors, and proteins such as albumin and immunoglobulins (antibodies that fight infection).

Which of the following elements would be the most reactive with other elements?
Multiple Choice
A. boron, #5
B. neon, #10
C. argon, #18
D. helium, #2
The chemical element which would be the most reactive with other elements is: D. helium, #2.
A chemical property is a property of a chemical substance that is observable and measurable in the course of a chemical reaction. The chemical properties of a chemical substance include the following;
Tarnishing.Heat of combustion.Flammability.Acidity.Chemical reactivity.Chemical reactivity is a property that determines how readily a chemical element would bond with other chemical elements to form a new compound.
Basically, the ability of a chemical element to bond with other chemical elements is highly dependent on the number of valence electrons.
The chemical elements Neon and Argon are noble elements, and as such have a filled outermost shell and wouldn't react with other chemical elements.
Helium has a single valence electron in its outermost shell while Boron has three (3) valence electrons in its outermost shell.
In conclusion, Helium with an atomic number of two (2) would be the most reactive with other elements.

In sexual reproduction, what fraction of genes does each parent contribute to the offspring?
1/2
3/4
1/3
1/4
Answer:
1/2
Explanation:
Well it's like you get 23 chromosomes from each parent. 23 from your dad, and 23 from your mom. In total that's 48 chromosomes, which 23 pairs of chromosmes. Have you ever seen those DNA testing kit commercials for "23 and me" yeah that's based off of the fact that every body has 23 chromosomes. Anyways the main thing is that each parent contributes 1/2 of genes to the offspring.
please please helppp meee A mammalogist is studying the behavior of the rain forest jaguar. She spots a jaguar
crouched on a tree branch in the understory, waiting to pounce on a rain forest herbivore
called a tapir. The hair of the jaguar is white with black spots. The jaguar has learned the
habits of this tapir, and he knows it uses this trail each evening. The cat is panting in the
steamy heat to stay cool, and its muscles tense as the tapir approaches. The jaguar pounces
and stabs its prey with long, sharp incisors. Although its meal is large, it will need to hunt
and eat again in a day or two to ward off its hunger.
Compose a four-to five-sentence paragraph that summarizes the general mammal
characteristics you can identify from the details of the story about the jaguar.
Answer:
The rainforest jaguar, exhibits a well-known mammal characteristic, as it waits for its opportunity to pounce on its prey. Mammals are known to be dominant in its environment, actively seeking its targets. Furthermore, the hairs on the jaguar would be an indicator of its status as a mammal. As mammals are known to have hair, and it is thus a mammal characteristic. They are known to be warm blooded, and one instance in the passage that hints at the jaguar's warm bloodedness would be when it pants in order to stay cool.
Note:
this is really vague lol, since I don't know your teacher's lesson plan, so I'm not sure what mammal characteristics are pointing towards (biological, or behavioral?) so note that this response might not be what your teacher is looking for.

What supplies energy for the water cycle?
Answer:
The sun!
Explanation:
Brainliest plss
Answer:
The sun is what makes the water cycle work. The sun provides what almost everything on Earth needs to go—energy, or heat. Heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds... clouds that move over the globe and drop rain and snow.

Two cells in the same organism differ only in the number of chloroplasts they contain. The first cell has multiple chloroplasts,
and the second cell has very few. What would most likely characterize these cells?
O There would be no difference between the functioning of the cells because the chloroplasts are not essential cell
structures
The second cell would become larger because it would have fewer chloroplasts regulating its size and shape.
O The second cell would shrink because it would not be able to store water and maintain cell shape.

Answer:
The second cell would not be able to produce as much food because it could not capture sunlight.
Explanation:
The second cell would not be able to produce as much food because it could not capture sunlight. The number of chloroplasts in a cell can also affect its shape and size, as well as its ability to store water, but the primary function of chloroplasts is to produce food through photosynthesis.
What are chloroplasts?Chloroplasts are organelles found in plant cells and some algae that are responsible for photosynthesis, the process by which plants convert light energy into chemical energy in the form of glucose. They are typically oval-shaped and range in size from 5 to 10 microns in diameter.
The chloroplast is surrounded by two membranes, an outer membrane, and an inner membrane, with a space between them known as the intermembrane space. The inner membrane encloses a fluid-filled space called the stroma, which contains enzymes and other molecules needed for photosynthesis.

Which of the following statements best describes the roles of the sympathetic and parasympathetic divisions of the autonomic nervous system, respectively?
A. Sympathetic helps the body achieve tension; parasympathetic allows the body to relax.
B. Sympathetic helps the body gain and conserve energy: parasympathetic prepares the body to react.
C. Sympathetic allows the body to relax; parasympathetic helps the
body achieve tension.
D. Sympathetic prepares the body to react; parasympathetic helps the body gain and conserve energy.
Answer:
D. Sympathetic prepares the body to react; parasympathetic helps the body gain and conserve energy.
Explanation:
the sympathetic system is your fight or flight response
parasympathetic system is the rest and digest
The statement, that is, the sympathetic prepares the body to react, and parasympathetic helps the body to conserve and gain energy correctly describes the functions of parasympathetic and sympathetic nervous system.
What are the functions of parasympathetic and sympathetic nervous system?Both the parasympathetic and sympathetic nervous system are the components of the autonomic nervous system. The sympathetic nervous system is situated close to the lumbar and the thoracic regions in the spinal cord.
Its main role is to instigate the body's flight or fight response. It does this by monitoring the rate of respiration and the rate of the heart. Therefore, it prepares the body to react.
On the other hand, parasympathetic nervous system is situated in between the medulla and the spinal cord, and works to stimulate the body's digest and rest and breed and feed response. Therefore, it helps the body to conserve and gain energy.
Thus, the correct statement is option D.

Proteins synthesis is accomplished primarily by the interaction of which two cell structures?
A:vacuoles and mitochondria
B:ribosomes and vacuoles
C:nuclei and ribosomes
D:nuclei and mitochondria
Answer:
C
Explanation:
Protein synthesis occurs through a chain of processes.
1) transcription of DNA in nucleus to form a RNA strand
2) RNA then undergoes modifications to form a mRNA
3) mRNA then migrates out of nuclear pore and complexes with a small and large ribosomal subunit to form a translational complex
4) translation occurs at the ribosomes to form a polypeptide by joining correct amino acids together through the formation of peptide bonds
5) polypeptide gets modified chemically and folded physically to form a protein in rough endoplasmic recticulum and golgi body.
Protein synthesis is accomplished primarily by the interaction two cell structures namely; nuclei and ribosomes.
PROTEIN SYNTHESIS:
Protein synthesis is the series of process that involves how proteins are produced by genes. Protein synthesis takes place in two stages namely: transcription and translation.TRANSCRIPTION:
Genes are stored in the nucleus as DNA, hence, the process of synthesizing mRNA from DNA called transcription, takes place in the nucleus.TRANSLATION:
Translation is the process whereby mRNA is used to synthesize proteins in the ribosome. The mRNA, produced in the nucleus of a cell moves to the ribosome, which is the site of protein production.
