Answer:
Neutrons do not carry an electrical charge so adding or removing them from the nucleus does not change the electrical charge of the nucleus. It does, however, change the mass of the nucleus. Adding or removing neutrons from the nucleus are how isotopes are created.
Explanation:

two examples of diffusion in plants and two in humans or animals.
Answer:
examples of diffusion in plants are:
The uptake of water and nutrients from the soil by the roots
The distribution of nutrients and water to all the parts of the plant
Diffusion of Carbon Dioxide into the leaf of the plants during photosynthesis
Release of oxygen out of the stomata of the leaf
Examples of diffusion in animals are:
Digested food molecules such as amino acids and glucose move down a concentration gradient from the intestine to the blood.
Waste products such as carbon dioxide or urea travel by diffusion from body cells into the bloodstream.
Oxygen moves from high concentration (in the air sac) to a lower concentration (in the blood). Carbon dioxide moves from high concentration (in the blood) to a lower concentration (in the air sac).
Explanation:
Which populations of species will be most likely to survive when environmental conditions shift?.
Answer: Small animals such as ants, some species of mice and rats, and cockroaches.
Explanation:
The smaller the animal is, the better chance it has to survive in drastic environmental change. (They will not be affected as much because of their size) Hope this helps :)

. Why is water so important to cells?
Answer:
Water is an essential constituent of the protoplasm of living cells because it is directly involved in countless biochemical reactions like photosynthesis and respiration. Without it cells couldn't move waste and by-products, take in nutrients, perform intracelluar transportation, functioning and signalling.
1)Which of the following parts of the body
has cortical motoneurons with the largest
representation on the primary motor cortex
(area 4)?
(A) Shoulder
(B) Ankle
(C) Fingers
(D) Elbow
(E) Knee
Answer:
Ankle
Explanation:
Ankle has cortical motoneurons with the largest representation on the primary motor cortex.
What is cortical motoneurons?"The neurons that lies in the upper motor cortex and is responsible for the voluntary movement."It is present in hands and ankle region.What is primary motor cortex?"The primary motor cortex is located in the precentral gyrus."It is composed mainly of motorneurons.It requires the least amount of electrical impulse for a movement.It generates signal to direct the movement of body.It is responsible for the complex voluntary movements.
Hence, the correct option is B. Ankle.

Explain the concept of nitrogen as a limiting nutrient? What are the consequences of over-fertilizing crops with NPK or nitrogenous fertilizers?
Answer:
Nitrogen is a substance for the production of ammonia NH3 and other substances, as well as for the growth of plants, which reaches the plant through the nitrogen cycle, but nitrogen fertilizers are also injected into the soil to strengthen the plant, but excessive injection of nitrogen fertilizer kills the plant.

Which of the following methods can be used to determine the relative age of rock and strata? Select all that apply.
Oceanography
Stratigraphy
Blostratigraphy
Archeology
Paleontology
Answer:
Stratigraphy and Biostratigraphy.
Explanation:
Relative dating is a method of determination of age, in which one object or organism is compared with the other object or organism found in the heap of strata. It is a method for determining the relative order of the past events, without stating the absolute age.
Stratigraphy is a branch of geology that studies the relative position of the sediments and rocks in the strata with respect to the geological timescale. Biostratigraphy is the branch of stratigraphy which deals with the relative aging of fossils with respect to the strata in which these are found defining a particular period of geological time scale.
