The diagram below shows several organisms in a fish tank.
Which item in the tank produces oxygen?

Answer:reproductive cells

Explanation: Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).

A mutant protein is the protein product encoded by a gene with mutation. Mutated protein can have single amino acid change (minor, but still in many cases significant change leading to disease) or wide-range amino acid changes by e.g. truncation of C-terminus after introducing premature stop codon.

What is protein? ... Most animal sources of protein, such as meat, poultry, fish, eggs, and dairy, deliver all the amino acids your body needs, while plant-based protein sources such as grains, beans, vegetables, and nuts often lack one or more of the essential amino acids.

Answer:

The correct answer would be - natural active immunity.

Explanation:

Active immunity is the immunity that includes that develops antibody by the immune system after exposure to a pathogen naturally through disease or artificially by the process of immunization. This type of immunity is a long-lasting immunity.

If the active immunity is deliberately developed by exposure of antigen to the patient is called Artificial active immunity whereas natural immunity takes place through contact with a disease-causing agent.

In my opinion, natural active immunity is best as it is a fact that natural infection almost always causes better immunity than vaccines.

Answer:

perform photosynthesis

The specific xylem and phloem tissues that vascular plants (tracheophytes) have for supporting and conducting water and food, respectively, set them apart from nonvascular bryophytes.Thus, option B is correct.

The existence of chloroplasts and the green pigment chlorophyll, which enable plants to carry out photosynthesis, is the fundamental similarity between these two plant groupings. Due to their capacity to manufacture their own food, plants are now the main contributors to the ecosystem's production.

Tracheophytes are another name for vascular plants. Pteridophytes, gymnosperms, and angiosperms are among them.Nonvascular plants lack the specialized vascular system required to transmit water and nutrients. Examples of simple structures that are specialized for doing transportation are those found in algae and bryophytes.

Therefore, perform photosynthesis characteristic is shared by the two plants.

Answer:

(-1,-3) on the coordinate grid.

Explanation:

The location from where Sam started his morning walk is 3 units to the left and 2 units up from the origin. This location is indicated by the point (-3,2).

He walked 5 units south and met his friend Joshua.

So, find the point that is 5 units to the south of point (-3,2). Distances north and south on the map represent a change in the y-coordinate. Moving 5 units to the south on the map from point (-3,2) places the new location at point (-3,-3).

Sam then walked 2 units east, where he met his friend, Ethan.

So, find the point that is 2 units to the east of point (-3,-3). Distances east and west on the map represent a change in the x-coordinate. Moving 2 units to the east on the map from point (-3,-3) places the new location at point (-1,-3).

So, Sam met Ethan at the location indicated by point (-1,-3) on the coordinate grid.

yoo i had this question on a study island!!

Answer:

The early ecologists who first studied succession thought of it as a predictable process in which a community always went through the same series of stages. They also thought that the end result of succession was a stable, unchanging final state called a climax community, largely determined by an area's climate.

Answer:

the answer is C

Explanation:

Even if organisms of different species combine their DNA to make offspring, the offspring will be sterile, unable to pass on their genes. Because of this restricted gene flow, each species evolves as a group distinct from other species.

The observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).

In conclusion, the observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).
