Answer:
In animals there are four types of tissues. Their functions are::
1. Epithelial tissue: covers body surfaces ,line the body cavities ducts and glands.
2. Connective tissue: support the body and binds body organ together and stores the fat.
3. Muscular tissue: contraction and movement
4. Nervous tissue: transmit nerve impulse that coordinate body activities.

What was the first element that developed in the universe after the Big Bang?
Explain why.
Answer:
Hydrogen
Explanation:
hydrogen couldn't form until the universe had cooled enough to allow their nuclei to capture electrons, about 380,000 years after the Big Bang, Within about 3 minutes after the Big Bang, conditions cooled enough for these protons and neutrons to form hydrogen nuclei.
Which of the following is an example of a detritus food chain?
A. Graas, Insects, Snakes.
B. Plankton, Large fish, small fish.
C. Organic matter, Bacteria, Molluscs.
D. All of the above.
Explanation:
Detritus food chain is the type of food chain that starts with dead organic materials. The dead organic substances are decomposed by microorganisms. The organisms that feed on dead organic matter or detritus, are known as detritivores or decomposers. These detritivores are later eaten by predators.
what makes jupiter similar to the sun
Answer:
Their composition is similar.
Explanation:
They are mostly made of hydrogen and helium.
The structure of jupiter and sun mostly made up of hydrogen and helium.
What are the characteristics of hydrogen and helium?Hydrogen and helium are the lightest elements in the periodic table. They exist as gases at room temperature and are the two most common elements in the universe, with hydrogen making up about 75% of all matter.
It will form a mixture of two of the lightest gases known. Though Hydrogen atoms (H) turn into hydrogen molecules (H2) to form a very reactive, flammable, and explosive hydrogen gas, Helium (He) atoms form an inert gas.
The key difference between hydrogen and helium is that hydrogen is a diatomic gas, while helium is a monatomic gas. Helium has a fully filled s orbital (1s2), but in hydrogen, there is only one electron, so it is unstable.

Do protists (amoeba, Euglena, Paramecium) use similar structures to move? Explain.
Answer:
Most protists move with the help of flagella, pseudopods, or cilia. Some protists, like the one-celled amoeba and paramecium, feed on other organisms. Others, such as the one-celled euglena or the many-celled algae, make their food by photosynthesis. ... Theyuse pseudopods to move away from bright light or to trap food.
Within the protist kingdom, organisms have developed very similar structures that are used to move around the environment.
The protist kingdom is primarily comprised of very small, single-celled organisms. Among the vast number of organisms that make up this kingdom are algae and amoebas. Over the course of history, these organisms have evolved very similar means of mobility.
Within the protist kingdom, most of the organisms move with one of the structures:
CiliaPseudopodiaFlagellaThese three structures used by protist to move are very similar in that are all structural extensions on the exterior limit of a cell. Though clear differences exist in the number or other uses of these extensions, it is clear that all of the members of this kingdom have evolved similar means of mobility.

How is a volvox different from the other protists?
Answer:
Volvox are protists that live in colonies, or groups of organisms living together. They are both autotrophs and heterotrophs. They use their eyespot to detect light when they undergo photosynthesis. They also have tails, or flagella, they use to move the colony.
describe the major disadvantages of asexual and sexual reporduction
Answer:
Asexual- No variation - if the parent has a genetic disease, offspring does too. Sexual- Requires two organisms, requires more energy
Explanation:
How is variation introduced into populations of asexual organisms such as bacteria and amoebas?
Answer:
In asexual reproduction an exact genetic copy of the parent organism is produced. Unlike sexual reproduction, asexual reproduction only introduces genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.

If 30% of the nucleotides in a single-stranded RNA molecule are adenine, then what percent are expected to be thymine?
Answer:
Explanation:
the base pair of adenine is thymine they are equal in amount in RNA so if 30% of the nucleotide in RNA is adenine so the percentage of thymine would also be equal to adenine that is 30%
If the DNA strand has 30% Adenine in its composition, it means that the same DNA strand has 30% thymine in its composition.
This is because:
DNA is composed of the nitrogenous bases Adenine, Thymine, Cytosine and Guanine.These nitrogenous bases were paired with each other.Adenine pairs with Thymina. While Cytosine pairs with Guanine.Therefore, the amount of Adenine and Thymine in a DNA must be equal. While the amount of Guanine and Cytosine must be equal.In this case, we can conclude that if the DNA has 30% of Adenine, it is mandatory that this same DNA has 30% of Thymine.

Identify the living and non-living parts of the nitrogen cycle.
The nitrogen cycle is a cyclical process in which nitrogen moves through both living and non-living things, including the atmosphere, soil, water, plants, animals, and bacteria.
What is nitrogen cycle?The Nitrogen Cycle is a biogeochemical process in which nitrogen is converted into various forms before passing from the atmosphere to the soil to the organism and back into the atmosphere.
Nitrogen fixation, nitrification, denitrification, decay, and putrefaction are some of the processes involved.
Nitrogen fixation, nitrification, and denitrification are the three major steps in the nitrogen cycle.
It is a biosphere cycle that includes the atmosphere, hydrosphere, and lithosphere. Nitrogen can be found in a variety of reservoirs.
The nitrogen cycle is a cyclical methodology in which nitrogen moves through both living and nonliving systems such as the atmosphere, soil, water, plants, animals, as well as bacteria.
Thus, these are some living and non-living parts of nitrogen cycle.
