Which behavior shows a way that animals defend their territory
Answers
Answer: Territorial behaviour, in zoology, the methods by which an animal, or group of animals, protects its territory from incursions by others of its species. Territorial boundaries may be marked by sounds such as bird song, or scents such as pheromones secreted by the skin glands of many mammals.
Explanation:
Answer:

Pandas evolved longer wrists to better eat bamboo over a long period of time and this in turn increase
their possibility of survival. This is an example of:
a. Artificial Selection
b. Adaptation
c. Biodiversity
d. Homeostasis
Answers
Answer:
B adaption
Explanation:
The scenario in which the Pandas evolve longer wrists to better eat bamboo over a long period will increase the possibility of artificial selection. The correct option is A.
What is artificial selection?Artificial selection, also renowned as "selective breeding," is the practice of selecting for positive traits in agricultural products or animals rather than allowing the species to change and evolve naturally, as in natural selection.
The process by which organisms can choose individual lifeforms with specific phenotypic trait values for breeding is known as artificial selection. If the selected trait has additive genetic variance, it will respond to selection, i.e., the trait will evolve.
Adaptation entails dealing with both the physiological abiotic environment such as light, dark, temperature, etc. but in addition to the intricate biotic environment.
Pandas evolved longer wrists to better eat bamboo over a long period of time and this in turn increase their possibility of survival. This is an example of artificial selection.
Thus, the correct option is A.

Name two types of lateral pathways for the movement of sucrose from source cell into the sieve tube
Answers
Answer:
Diffusion and active transport.
Explanation:
Diffusion and active transport are the two types of lateral pathways that is responsible for the movement of sucrose from source cell into the sieve tube. Sugar molecules are moved into the sieve elements which are the phloem cells through active transport i.e. with the use of energy. The water produces turgor pressure in the sieve elements, which pushes the sugars and fluids down the phloem tubes toward the storage sites. it also moved through simple diffusion due to difference in concentration i.e. from higher to lower concentration region.

Hence, option C is correct
Which type of macromolecules helps a cell brake down food? Lipids proteins carbonhydrates or nucliec acids
Answers
Answer:
Proteins
Explanation:
There are four major biomolecules found in living system namely; proteins, carbohydrates, lipids and nucleic acids. These biomolecules serve different and unique functions in the body. PROTEIN is a biomolecule that helps in the break down of food substances in the body as stated in this question.
Specifically, these function of breaking down food substances is carried out by ENZYMES, which are biological catalysts that are proteinous in nature i.e. structurally made of proteins. For example, amylase enzyme breaks down starch, lipases break down lipids. Hence, since enzymes that perform this disintegration function are PROTEINOUS, then PROTEINS are the biomolecules that perform the role.
A cell membrane is composed of a lipid bilayer in which many kinds of proteins are embedded. These proteins use energy to actively transport certain particles into and out of the cell.
Which example BEST illustrates the condition in which molecules move across the cell membrane through active transport?
A. When molecules need to move from an area of lower concentration to an area of higher concentration.
B. When the cell wall is damaged or genetically modified and molecules cannot enter or leave the cell.
C. When molecules need to move from an area of higher concentration to an area of lower concentration.
D. When the amount of water is higher inside of the cell as compared to the area surrounding the cell.
