Answer:
The correct answer is option (B) "a community".
Explanation:
A biological community is defined as a group of organisms from various species that interact within a defined location. A biological community is one of the smallest categories of ecology, since it comprises a small location and the interaction of few species. An example of a biological community is the group of some organisms living in a vacant lot include grass, dandelions, mice, grasshoppers, and slugs.
During the process of photosynthesis ,energy from the sun is converted into chemicalenergy.
Photosynthesis involves green plants using light energy from the sun to
produce their food ( starch). This process involves series of reactions and it
provides food for consumers in the ecosystem
The product formed is Starch which is a form of chemical energy as it
contains compounds which when broken down gives cells energy.

Answer: The correct answer is- Hyphae.
Mushroom belongs to the kingdom fungi, which includes any group of eukaryotic organisms that are having microorganisms such as yeast, moulds, and mushrooms.
Many species of fungus exhibit slender, filamentous structures, known as hyphae. In most fungi, hyphae are considered as the primary mode of vegetative reproduction and form a vegetative part of fungus, termed as mycelium.
Therefore, the slender filaments that make up the body of a mushroom are called hyphae.
B. vesicle
C. ribosome
D. Golgi apparatus
The right answer to this question is option D. Golgi apparatus.
First things first, you need to truly understand how the process of making a protein works since the DNA reading. After this reading, a single ribbon of mRNA is sent outside the cell, after that, this mRNA is read by the anticodons on the tRNA/ribosomes, and by that, simplifying it to you, the cell makes a protein, made of aminoacids.
But where are the organelles in this process? We already know one, ribosomes, they make the protein for the body, and after that, the protein is sent to the Golgi apparatus, it's here that this organelle will either add carbohydrates or just send the protein outside the cell through a secretion vesicle.

B) In any population, variation exists. Some bacteria are resistant to antibiotics. Most bacteria die, but the bacteria that are resistant survive and reproduce.
C) In a population of bacteria that are exposed to antibiotics, some bacteria change their genetic make-up and survive. The new genetic make-up is passed on to offspring.
D) There is a change in the environment: an antibiotic is added. Some of the bacteria are capable of changing to the new environment. They survive and reproduce, passing along their favorable traits.
Answer:
The most appropriate answer would be D) There is a change in the environment: an antibiotic is added. Some of the bacteria are capable of changing to the new environment. They survive and reproduce, passing along their favorable traits.
Natural selection refers to the process by which organisms who are better adapted to the change in the environment have better chances for survival and reproduction.
The steps for natural selection can be explained as:
I. Inherited variation: Within a population, organisms often exhibit variations which can be inherited such as color, size, et cetera.
II. Competition: This is the phase in which organisms struggle to survive. During this, species usually produce more offspring as compared to the carrying capacity of the environment.
In the given situation, environment change is the addition of antibiotic.
III. Selection: It is the phase of differential reproduction that is, organisms who are best adapted to the environmental change have better chances to mature to reproductive age. They reproduce and pass the beneficial traits to the offspring.
Bacteria which are better adapted to the new environment survive, reproduce, and pass their beneficial traits to the next generation.
IV. Evolution: Changes in allele frequency in a population accumulate over time and leads to the evolution.
