If a biologist is measuring diversity by calculating the proportion of individuals of each species, he or she is actually calculating the species evenness of species in the community.

<h3>What is species evenness?</h3>
  • When there is an environmental gradient in the study region, systematic sampling is performed.
  • To take systematic samples along the environmental gradient, a transect is utilized.
  • A population is a collection of creatures belonging to the same species that coexist in a certain location.
  • Within a given area, more than one population may exist.
  • It's possible for populations of Saguaro cacti, Cactus Wrens, and Bark Scorpions to coexist in the same places.
  • A population is a collection of people belonging to the same species who are present in the same location at the same time.
  • All of the people in all of the interacting populations in a given area make up a community.

Which of the following are reactants in the process of aerobic respiration?
trasher [3.6K]

Answer:

Glucose and oxygen are the reactants in the process of aerobic respiration.

Explanation:

There are two types of respiration i. e. aerobic respiration and anaerobic respiration. In aerobic respiration, food molecules are broken down in the presence of oxygen which produces carbondioxide, water and energy in the form of Adenine tri phosphate (ATP). Anaerobic respiration occurs in the absence of oxygen.

zaharov [31]

Answer:

The number of protons in it.

Explanation:

There are two properties that can be used to identify an element:

  • the atomic number  
  • the number of protons in an atom.

The number of neutrons and number of electrons are frequently equal to the number of protons, but can vary depending on the atom in question

Name three different cells in a leaf that contain chloroplast. Please help​
xenn [34]

The leaf as a photosynthetic organ includes the following cells which contains chloroplasts

--> the palisade mesophyll

--> the spongy mesophyll and

--> the stomatal guard cells

Although all the green parts of a plant can be involved in the photosynthetic activities (with the exception of the root hairs), the leafs are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the chloroplasts of these plant. Chloroplasts are structures that contains chlorophyll which traps in energy from the sunlight.

The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous chloroplasts and is the main site of photosynthesis in the leaf.

The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain chloroplasts.

The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains chloroplasts which contributes to the movement of stomata.

Therefore the three different cells of the leaf that contains chloroplasts are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.

A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: A.Osmosis
madreJ [45]

Answer:

B.Active transport, because energy is being used to move molecules against the concentration gradient

Explanation:

Substances move in and out of living cells through various transport means. Some substances move passively (without energy) while others move actively (with energy). Active transport of substances involves the movement of molecules against the concentration gradient.

Active transport moves against concentration gradient in the sense that the movement occurs from a region which is less concentrated to one which is more concentrated, hence, energy input in form of ATP is required for such transport to occur. This is the case of the cellular transport in the diagram. Therefore, it is an ACTIVE TRANSPORT because energy input (ATP) is required.

Note, Osmosis and facilitated diffusion are types of passive transport that requires no energy to occur.
