Answer:
Node
Clade
Taxa
Explanation:
Node is a point in a cladogram where a single ancestral lineage breaks into two or more descendant lineages. A node usually has similar characteristics due to the common ancestral lineage.
Clade is a group of organisms that includes an ancestor and all of its descendants. An example is birds, dinosaurs and crocodiles all belonging to a common ancestor as animals but different descendants.
A taxa is any named group of organiſms,
whether they form a clade or not. It represent any level of taxonomic groupings.

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.

Hope its helpful ❤❤❤❤❤A pair of mice are bred several times generating the following data table. What are the most likely genotypes of the parents?
Answer:
This question lacks options, the options are:
A) FF and ff
B) FF and Ff
C) Ff and Ff
D) Ff and ff
The answer is D (Ff and ff for parent 1 and 2 respectively)
Explanation:
This question depicts a single gene coding for fur colour in mice. The gene controls two traits, black fur and white fur, encoded by alleles F and f respectively.
According to the question, a pair of mice has been bred several times to generate the same data of 22 black fur and 23 white fur mice. Based on this data, it shows that the phenotypic ratio of black to white mice is 1:1.
To get a 1:1 phenotypic ratio of black fur offspring to white fur offspring, the parents mice must have genotypes Ff (heterozygous) and ff (same recessive alleles).
In a cross between parents Ff × ff (see punnet square), offsprings with the following genotypes will be produced: Ff, Ff, ff and ff. Ff is black furred while ff is white furred.
Ff (2) : ff (2) is equivalent to Ff (1) : ff (1).
Hence, a data of 22 black mice and 23 white mice which represents a 1:1 ratio will only be produced by parents mice with genotypes: Ff and ff.

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.

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.

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.
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
