Answer:
Father's genotype is T T, E e
Mother's genotype is t t, E e
Explanation:
Tasting PTC
Let the characters for tasting and not tasting PTC be T and t respectively.
Since all the children can taste PTC, it can be deduced that tasting PTC is a dominant trait.
The man will be homo-zygous dominant for tasting PTC while the woman is homo-zygous recessive for tasting PTC.
Genotype of man is T T and genotype of woman is t t
T T x t t = T t, , T t, T t; which is a 4:0 phenotype.
Earlobes:
Let the characters for Free and attached earlobes be E and e
Since both the man and woman have free earlobes and 3 out of 4 children have free earlobes, it can be deduced that free earlobes is dominant while attached earlobes is recessive.
The ratio of free to attached earlobes is 3:1
The man and the woman are both hetero-zygous dominant, E e for free earlobes, so that a cross between them will yield three hetero-zygous dominant for free earlobes and one homo-zygous recessive for attached earlobes.
E e x E e = E E, E e, E e, e e; which is a 3 : 1 phenotype.

why is there a greater volume of living organisms at the bottom of the energy pyramid?
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

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.

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.

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.

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.

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.

What is the role of each of the following in the carbon cycle? Include an example of each. a) Producer b) Primary consumer c) Decomposer
Answer:
Explanation:
Producer- plants like grass
primary consumer- herbivore , like a rabbits
decomposer - earthworms and maggots.
Producer consumes carbon whereas primary consumer and decomposers consumes as well as releases carbon.
Producer takes inside carbon in the form of carbondioxide gas which is used as a raw material in the process of photosynthesis while on the other hand, primary consumer consumes carbon in the form of starch and cellulose by eating producers and releases carbon in the form of carbondioxide in the atmosphere. Decomposer feeds on carbon that is present in the dead bodies of animals and plants which also releases carbon in the form of respiration so we can conclude that producers take inside carbon whereas primary consumers and decomposer releases carbon in the atmosphere.
