Why might a plant cell need to have a bigger vacuole than an animal cell?
Answers
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.
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?
Answers
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.
It was once thought that decaying meat turns into maggots. Careful experimentation by scientist demonstrated that maggots actually come from fly eggs and not meat. These experiments illustrate that the new individual results only from reproduction and development
Answers
Answer:
True
Explanation:
Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
It thus showed that new life does not arise spontaneously but rather through development and reproduction.

what kinds of bacteria are spherical, endospores,cocci, bacilli, spirilla
Answers
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.
Therefore, the correct option is C.

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?
Answers
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 type of asexual reproduction is shown in the picture above?
O binary fission
Obudding
O regeneration
O vegetative propagation
Answers
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.

Answers
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.

Name one disadvantage of light microscopes
Answers
Answer:
We can't examin the specimen in tbe absence of lght. We can not study the internal structures.
Explanation:
Answer:
Light microscopes do not magnify at the same level as other options.
The typical light microscope cannot magnify as closely as an electron microscope when looking at some of the world’s smallest structures. Most models are capped at 2,000 times or thereabouts, with some entry-level models offering significantly less to the user. Because the relatively long wavelength of light decreases the ability of the equipment to magnify in the small focus lens, you may not always see everything that is going on with a slide when choosing this option.
