Use the diagram above to explain how breathing,digestion,and cellular respiration work together to create energy in an animal
Answer:
As breathing brings in O2 (oxygen) and the digestive system breaks food down into smaller parts, like glucose, it gives cells all the needed parts in order to do cellular respiration.
A species of bacteria is found deep within the Earth's crust. Which process will the bacteria use to obtain energy? A. Cellular Respiration B. Photosynthesis C. Lactic Acid Fermentation D. Alcoholic Fermentation
Answer:
CELLULAR RESPIRATION
Explanation:
The process that the bacteria will use to obtain energy deep in the Earth's crust by cellular respiration. The correct option is A.
What is cellular respiration?Bacteria use both aerobic and anaerobic cellular respiration. There are three major steps in aerobic cellular respiration: glycolysis and the citric acid cycle in the cytoplasm, and the electron transport chain in the plasma membrane.
The process of respiration in bacteria is carried out by mesosomes. Mesosomes are rolled up invaginations in bacteria's cell membrane.
Their purpose is to increase the required surface area for respiration. They are respiratory activity sites because they contain respiratory enzymes.
The process by which bacteria will obtain energy deep within the Earth's crust through cellular respiration.
Thus, the correct option is A.

Why might a plant cell need to have a bigger vacuole than an animal cell?
Answer:
A plant cell might need a bigger vacuole than an animal cell because when a plant has stopped growing, there is usually one very large vacuole, sometimes taking up more than half of the cell’s volume; plants have a large sized vacuoles because it also provides turgidity and rigidity to the plant.
Which cell organelle underwent a change that caused this plant to wilt and droop? Which cell organelle helps the plant maintain its structure during such stress?Which condition is required for viruses to reproduce?
Answer: A vacuole undergoes a change in the plant causing wilting and droping.
Explanation:
The vacuole is an organelle, which is a store house of excess water and stored materials. During dehydration, the plant uses water from vacuole. Thus water and stored materials reservoirs get consumed up in this process, the plant experiences scarcity of water. This causes wilting and droping of plant.
The cell membrane is an envelop outside the cells, which causes plants to maintain their structure during stress for example, plant exposed to hypertonic solution. This prevents the cells to burst.
A virus require a living host. A host can be a plant, animal, human, or any other living organism. It does not have a cellular machinery thus uses host cell machinery to replicate its genetic material and produce its progeny.

which best describe how mRNA is used by a cell
Answer:
Explanation:
Messenger RNA (mRNA) carries the genetic information copied from DNA in the form of a series of three-base code “words,” each of which specifies a particular amino acid. Translation is the whole process by which the base sequence of an mRNA is used to order and to join the amino acids in a protein.

What type of asexual reproduction is shown in the picture above?
O binary fission
Obudding
O regeneration
O vegetative propagation
The given image asexual reproduction represents binary fission. The correct option is A.
What is binary fission?In biology, fission is the division of a single organism into two or more pieces, followed by the regeneration of those parts into new, distinct organisms that resemble the original.
Asexual reproduction by splitting a body into two new bodies is known as binary fission.
When an organism divides into two halves (cytokinesis) through binary fission, it doubles its genetic material, or deoxyribonucleic acid (DNA), with each new creature acquiring one copy of the latter.
Divide into two is what binary fission refers to. It is the most straightforward and typical kind of asexual reproduction.
Thus, the correct option is A as it is showing the splitting of one cell into two.

Describe the movement of water molecules in this diagram and identify the state of the solution. Explain why the water molecules moved I bc this direction
Answer:
the answer is they move freely
Explanation:
Answer: The substances like CO2 and water move in and out of a cell by diffusion from the region of high concentration to low concentration.
Explanation: In osmosis, water always moves from an area of higher water concentration to one of lower concentration. In the diagram shown, the solute cannot pass through the selectively permeable membrane, but the water can.

A student working on their science experiment places four potato squares into solutions of Iodine and measures how far the Iodine diffuses into the potato. The measurements are: 2.1 mm, 1.8 mm, 2.3 mm, and 2.2 mm. What is the average diffusion distance?
Answer:
The average diffusion distance is 2.1 mm
Explanation:
Given
Diffusion distance of the four potato squares are;
[tex]Potato 1: 2.1 mm\\Potato 2: 1.8 mm\\Potato 3: 2.3 mm\\Potato 4: 2.2 mm[/tex]
Required
Average Diffusion Distance
To calculate the average diffusion distance; we simply calculate the mean of the student recordings
Mean is calculated as thus;
[tex]Mean = \frac{\sum x}{n}[/tex]
Where x is the individual distance of the potato squares
[tex]\sum x = 2.1 mm + 1.8 mm + 2.3 mm + 2,2 mm[/tex]
[tex]\sum x = 8.4mm[/tex]
n is the number of potato squares
n = 4
[tex]Mean = \frac{\sum x}{n}[/tex]
[tex]Mean = \frac{8.4 mm}{4}[/tex]
[tex]Mean = 2.1 mm[/tex]
Hence, the average diffusion distance is 2.1mm
what kinds of bacteria are spherical, endospores,cocci, bacilli, spirilla
The cocci kind of bacteria are spherical in shape. Rod-shaped bacteria are bacilli, and spiral-shaped bacteria are called spirilla. Thus, the correct option is C.
What are the cocci bacteria?A coccus or cocci bacteria is any bacterium or archaeon which has a spherical, ovoid, or generally a round shape. Bacteria are categorized into different classes on the basis of their shapes into three classes which are cocci (spherical-shaped bacteria), bacillus (rod-shaped bacteria) and spiral (two types: spirillum and spirochete bacteria).
Different classes and examples of bacteria are Streptococci, in which cocci are arranged in chains. Example: Streptococcus mutans. Diplococci, in this cocci are arranged in pairs. Example: Neisseria gonorrhoeae. Monococci are single cocci. Staphylococci are the clusters of cocci. Example: Staphylococcus aureus.

Watersheds may be contaminated by fertilizers and other pollutants. When these substances enter a waterway, they can cause algal blooms, which are rapid overgrowths of algae. When the algae die, the decay uses up a large portion of dissolved oxygen. Declining oxygen levels can then cause large die-offs of animals in the waterway. What will an algal bloom in a watershed most likely cause?
Completed options
A)A decrease in the watershed’s biodiversity, which will reduce its ability to supply clean and safe drinking water.
B)A decrease in the watersheds ecosystem diversity, which would improve its ability to supply large volumes of water.
C)An increase in the watersheds genetic diversity, which would reduce its ability to supply clean and safe drinking water.
D)An increase in the watersheds species diversity, which would improve its ability to supply large volumes of wate
Answer:
)A decrease in the watershed’s biodiversity, which will reduce its ability to supply clean and safe drinking water.
Explanation:
This sequnces of events is called Eutrophication. It is the process of washing of nutrients salts e.g., (NPK) into aquatic bodies which leads to change in the ecosystem structure of the aquatic bodies with the boom in algae growth, and drop in O2.
The cut in oxygen availability in the aquatic bodies , leads to death of the fauna and flora.Theses are the varieties of life in this habitat.(biodiversity).
With the an increase in the death of these inhabitants(flora and fauna)couple with the activities of the (decomposers) the water bodies becomes dirty and unfit for drinking.
Besides as the pathways of the watershield ecosystem as it filters the these polluted water may be blocked by the dead organic matter from the flora and fauna. Thus A is the best.
