What are the three main weapons of predators?

Answers

Answer 1

Answer: Predators possess usually good senses to find their prey and special abilities to trap the prey. Predatory birds, for example, had an outstanding eyesight and sometimes hearing, for the case of the owls while other predators, like many species of mammals, have a very high sense of smell that helps them locate prey. Many predators are very fast, and use their speed to help capture their prey, some are fastest runners, fast fliers and fast swimmers.

Answers

The answer is skin.

There are four basic types of animal tissue - epithelium, connective, nervous, and muscle tissue. Epithelial cells form epithelium which covers surfaces of blood vessels and organs in the body. All glands are, as well, made of epithelial cells. Also, epithelial cells grow close together to form the body's skin.

Which base is found in RNA but NOT in DNA? A) adenine B) cytosine C) thymine D) uracil

Answers

Its Uracil.Uracil is energetically less expensive to produce than thymine, which may account for its use in RNA. In DNA, however, uracil is readily produced by chemical degradation of cytosine, so having thymine as the normal base makes detection and repair of such incipient mutations more efficient

The DNA nucleotide bases include adenine, cytosine, guanine and thymine. The RNAnucleotide bases include adenine, uracil, guanine and cytostine.

In which step of the scientific method is information obtained through the senses?a. drawing conclusions
b. making observations
c. analyzing data
d. revising a hypothesis

Answers

The scientific method of making observations is how information isobtained through the senses. A person can see, touch, smell and hearthings in order to make an educated guess to how things will end uppanning out for whatever scientific things they are researching.

Making observations is the step of scientific method in which information is obtained through the senses.

Making an observation is the first step of scientific method where scientists gets curious about a natural occurrence or a phenomenon.

Further Explanation.

Scientific method involves a process where researchers or scientists search for answers to certain questions and solutions to problems.
Scientific methods are used by scientists or researchers to test a given hypothesis.

Steps involved in Scientific method

Making an observation and asking question.

Making observation is the first step of any scientific process. The scientists make observations about a natural phenomenon.

After making observations scientist asks a question about an observed phenomenon or pattern.

Observations may be qualitative where the occurrences are described in ways that do not use numbers or quantitative where observations contain numbers and other features.

Formulating a hypothesis

Hypothesis refers to probable answers to the question asked and one that can be tested experimentally. Hypothesis is therefore a possible explanation for a given observation or occurrence.

For the observation that we experience alternating periods of light and darkness that correspond to the movement of the sun, moon, and clouds. The hypothesis here would be; The earth rotates on its axis for 24 hours, thus, exposing one side to the sun or else the sun revolves around the earth for twenty four hours.

Designing and performing experiments

Suitable experiments be carried out to test the validity of the hypothesis formulated.

Experiments refers to organised measurements or observations normally made under controlled environment.

Accept or modify the Hypothesis

The experiment conducted helps the researchers or scientists to determine whether the hypothesis formulated is valid. If the hypothesis is valid then they proceed to the next step of scientific method.

However, if the experiments demonstrate that the hypothesis is incorrect then it must be corrected for further experimentation.

Developing a law and/or a theory

After conducting experiments and analyzing the results obtained, the researchers may test whether the results are reproducible and hence a law may formulated to allow general prediction.

A scientific law describes a phenomenon or pattern, it describes what happens but does not explain why.

Which of the following is not a vascular plant?conifer
fern
moss
flowering plant

Answers

The answer is moss.

Mosses are nonvascular seedless plants. Nonvascular plants have simple tissues specialized for internal water transport.
On the other side, vascular plants have vascular tissue which consists of xylem and phloem. Xylem transport water and minerals from the root to the upper parts of the plant. Phloem transports food and nutrients from the leaves, where they are produced, to the growing or storage parts of the plants.

The tissue responsible for transporting carbohydrates from leaves to other parts of the plant. a) xylem
b) phloem
c) cambium

Answers

B. Phloem is the tissue responsible for transporting carbohydrates from leaves to other parts of the plant.

Phloem is the right answer

Which statement is true for both incomplete and complete digestive systems? A. Materials enter and exit through the same opening. B. Digestion begins outside the cells. C. The digestive cavity is like a tube. D. Continuous feeding is possible.

Answers

B. Digestion begins outside the cells statement is true for both incomplete and complete digestive systems

Further explanation

"Digestion begins outside the cells" is the statement that is true for both incomplete and complete digestive systems

Because digestion occurs outside the cell, it is said to be extracellular. Intracellular digestion thus means digestion that occurs inside our cells. Extracellular digestion takes place either in the lumen of the digestive system, in a gastric cavity or other digestive organ, or completely outside the body.

The prefix "extra" means "outside the thing ", and "extra" indicates that extracellular digestion must occur outside the cell. The definition of extracellular digestion is a process in which saprobionts feed by secreting enzymes through the cell membrane onto the food.

During extracellular digestion, food is broken down outside the cell. It is done either mechanically or with acid by special molecules called enzymes. Then the newly broken down nutrients can be absorbed by the cells nearby. Humans use extracellular digestion when they eat.

Extracellular digestion in our human digestive system occurs in the alimentary canal which runs from the starting point of digestion, our mouths, to the end of the digestive system, our anuses.

The true statement from all the given options is (B) digestion begins outside the cells.

Further Explanation-

Digestion is the process of action of enzymes and physical force exerted by the digestive system which results in chemical and physical breaking of the food consumed.

There are two types of digestion extracellular and intracellular digestion. Extracellular digestion is the process by which the cells secrete a type of enzyme which helps to digest the food outside the cell. While intracellular digestion is the process by which breakdown of food molecules occurs inside the cell cytoplasm.

If digestive system is to be classified they can be identified into two types,

A. Incomplete Digestive system.

B. Complete Digestive system.

Incomplete digestive system is the one which consists of a single opening for both ingestion of food and excretion of the waste particles.

While on the other hand complete digestion consists of a tube that has two openings, one for ingestion and the other for excretion of the waste products.

In humans the digestion is generally extracellular as the cells associated with our digestive system is secretive in function. These cells secrete enzymes which help in the digestion of the food ingested. As the process occurs in the lumen of our digestive system it is termed as extracellular.

Food is ingested at the start of the digestive system that is mouth. This food passes through the digestive tract wherein the secretion of enzymes brings about the digestion of the food. At last the waste undigested food makes it way out through anus.
