Which statement correctly describes the difference between cellular respiration and photosynthesis?
A.
Photosynthesis involves chemiosmosis, and cellular respiration doesn’t involve chemiosmosis.
B.
Photosynthesis doesn’t produce any ATP, and cellular respiration produces ATP.
C.
Photosynthesis occurs during the day, and cellular respiration occurs at night.
D.
Photosynthesis creates energy that the plant stores, and cellular respiration utilizes the energy.
E.
Photosynthesis is an anabolic reaction, and cellular respiration is a catabolic reaction.
Answer:
The answer is E.
Explanation:
An anabolic reaction is one that involves the building of complex substances from simple ones and it uses up energy. Photosynthesis is an anabolic reaction because It requires energy.
A catabolic reaction is one that involves the breakdown of complex substances into simpler ones and in the process energy is released. Cellular respiration is catabolic because energy is released during this process.

Explanation:
Which type of growth can occur only when a population has unlimited resources?
limited
logistic
exponential
negative
Answer:
c. on edge
Explanation:
When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. The correct answer is c) exponential.
What is the exponential growth curve?Exponential growth curves and logarithmic growth curves are the two different forms of growth curves. In an exponential growth curve, the slope increases steadily over time. A logarithmic growth curve has a steeply increasing slope that gradually flattens out over time.
The exponential growth curve, which has a J-shape, shows a period of time where the results develop rapidly and steadily. It is the reverse of gradual progress. This curve initially climbs gradually before accelerating, which represents multiplied growth.
With exponential growth, a population's growth rate per capita (per person) remains constant regardless of population size, causing the population to expand exponentially as it grows larger. In nature, populations may expand exponentially for a while, but ultimately, their growth will be constrained by the availability of resources.
Exponential expansion happens when resources are unrestricted. Due to the favorable conditions, there are a lot more births as a result of the food excess.
Therefore, the correct answer is c).

In a moth population, 47 are brown, 15 are yellow, and 34 are black. What is the approximate probability of a moth being black?
A. 2%
B. 49%
C. 16%
D. 35%
Answer:
D
Explanation:
34/96= 35%
The mathematical rule of three can be used to take probabilities. In the exposed example, the approximate probability of a moth being black is 35% (Option D).
------------------------
Available data:
47 moths are brown15 moths are yellow34 moths are blackThe total number of individuals in this population equals the addition of brown, yellow, and black individuals.
This total number of individuals equals 100% of the population.
So to get the probability of a moth being black, we can just perform a rule of three.
To do it, we need to get the percentage of black individuals in the current population.
96 moths ------------------------- 100% population
34 black moths ----------------- X= (34 x 100) / 96
=35.41 ≅ 35% of the population
The approximate probability of a moth being black is 35%.

Can the carrying capacity of an ecosystem change?
Answer:
no the carrying capacity of an ecosystem can't change
it is literally impossible hope it helps you have a good day please mark me as brain list
Answer:
No carrying capacity of an ecosystem doesn't change.
Explanation:
Each organism that lives there will have a different carrying capacity, one that interacts with everything around it. If the climate changes and the resources a particular animal needs for food drop, for example, that change in carrying capacity for one species will affect other populations in the area.

Answer:
The correct answer is - Deltoid
Explanation:
Deltoid muscles are thick triangular muscles that help in raising and rotating arm covers shoulder joints. It originates lateral third of the clavicle, inferiorly along the spine of the scapula to the acromion.
Deltoid muscles provide actions that include flexion and medial rotation, abduction, and extension, and lateral rotation at the shoulder joint. Deltoid means triangle or that has three sides as it has three originating sides.

Every organism requires a set of instructions that specifies its traits. This information is carried with the cells of the organism. Which set of statements BEST describes hereditary information in eukaryotic cells? Group of answer choices
Answer:
This question lacks options, the options are;
A. Genes are made up of chromosomes and both are found in the cell’s cytoplasm.
B. Chromosomes are made up of genes and both are found in the cell’s cytoplasm.
C. Genes are made up of chromosomes and both are found in the cell’s nucleus.
D. Chromosomes are made up of genes and both are found in the cell’s nucleus.
The correct answer is D.
Explanation:
As rightly stated in this question, every living organism requires a set of instructions that specifies its traits. These set of instructions are embedded in a unit called GENE. Genes hold information needed for the survival of a cell in an organism.
These genes are located on a structure called DNA, which are folded or packaged into another structure called CHROMOSOMES. Each chromosome, hence, contains genes that are the unit of inheritance of a cell. In eukaryotic organisms, the gene is found on a chromosome, which is located in the NUCLEUS of the cell.
