In humans, three alleles affect blood type. The A and B alleles are codominant, and the O allele is recessive. An AB blood type father has children with an A blood type mother (genotype AO). What are the chances that their children will have AB type blood? Choose 1 answer: Choose 1 answer: (Choice A) A 25\%25%25, percent (Choice B) B 50\%50%50, percent (Choice C) C 75\%75%75, percent (Choice D) D 100\%100%100, percent

Answers

Answer 1

Answer:

The correct answer is - A. 25%.

Explanation:

In humans, the blood group system is known as the ABO system where blood groups A and B are codominant and O blood group is recessive. The genotype of the A blood group could be AA or AO similarly for the B blood group genotype would be BB or BO, for the O blood group OO whereas for the AB blood group both A and B alleles should be present together.

Cross: AB blood type father with an A blood type mother (genotype AO)

Gametes: A, B and A, O

Punnett square:

       A       B

A    AA     AB

O    AO    BO

Here, there are 25% chances of AB blood group offspring 50% for the A blood group (AA and AO) and 25% B blood group (BO).

Ryland is setting up a cooler to store flowers for a big event. Which of the following is NOT going to contribute to ethylene build up in his cooler?

O Gas leaks
O Succulents and cacti
O Old flowers
O Ripening fruit

Answers

Answer:

Gas leaks

Explanation:

I don't know anything about biology but I know gas leaks aren't good for plants

The option that will not contribute to ethylene building up in Ryland's cooler would be gas leaks.

Ethylene plant hormone

Ethylene is an important hormone for plants that regulate processes such as leaf/fruit abscission, fruit ripening, and senescence.

Thus, keeping succulents and cacti, old flowers, and ripening fruit in the cooler would be a good recipe for ethylene building up in the cooler.

Gas leaks may not find its way into the cooler as long as it is closed.

✎﹏☾✦☁️❣️ Briefly explain the process of photosynthesis .❣️☁️​

Answers

Answer:

hope this will help u

Explanation:

photosynthesis is the process in which plant make their own food with the help of sunlight,water and carbon dioxide. water and carbon dioxide are raw materials in photosynthesis because they help to prepare their food.During photosynthesis, plants take in carbon dioxide and water from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Explanation:

PHOTOSYNTHESIS

This is a process in which green plants and other organisms make their own food from simple inorganic substances which are sunlight ,CO2 and chlorophyll.

A. mitochondria, oxygen
B. chloroplast, oxygen
C. mitochondria, carbon dioxide
D. chloroplast, carbon dioxide

Answers

Answer:

B. chloroplast, oxygen

Explanation:

This is because plants take in the carbon, water, air,and it transforms the water into oxygen and carbon into glucose. So it absorbs light, and the chloroplasts are special structures that are responsible for that absorption of light, They are green, because of chlorophyll, which gives the green pigment to leafs

photosynthesis takes place inside them, so they can absorb light to start the process.

Based on the living things in the pyramid, please tell me what examples would fit into these categories
Primacy Producers, primary consumers, secondary consumers, and tertiary consumers.

Answers

Answer:

Primacy Producers----- Oak tree , primary consumers------ Caterpillars , secondary consumers ------- blue jays, and tertiary consumers ----- hawk.

Explanation:

Oak tree refers to the primacy Producers in this pyramid because it produces food by using the solar energy. Caterpillars are primary consumers that feeds on the producers and also known as herbivores, blue jays are the secondary consumers that feeds on the primary consumer which is the caterpillar, and tertiary consumers are the hawk that feeds on the secondary consumer i.e. blue jays. In this way, energy flows in the food chain of an ecosystem. During this flow of energy, only 10% of energy is transferred from one trophic level to another while the remaining releases in the environment in the form of heat energy.

a. a volcanic area
b. the effect of a mountain system on Jupiter's wind system
c. a zone of high ammonia concentration
d. a large rotating hurricane-like storm (cyclone)
e. none of these

Answers

It’s a huge typhoon-like storm of swirling gasses. A long-lived, oval cloud circulation similar to a hurricane on Earth.

The Great Red Spot, a permanent region of high pressure in Jupiter's atmosphere, is responsible for producing the largest anticyclonic storm in the Solar System. Thus, option D is correct.

What Jupiter's Great Red Spot rotating hurricane-like storm?

In Jupiter's atmosphere, there is a huge, rotating storm known as the Great Red Spot. It is similar to an Earthly hurricane, but considerably bigger.

The Great Red Spot on Jupiter is larger than Earth by more than two times! Within this storm, winds can gust as high as 270 miles per hour (ca. 435 km/h).

When astronomers first focused their telescopes on Jupiter in the 17th century, they discovered a striking reddish patch on the massive planet. More than 300 years later, the Great Red Spot is still visible in Jupiter's atmosphere. It is now understood to be a big storm that is rotating like a cyclone.

Therefore, Jupiter's Great Red Spot is believed to be (a large rotating hurricane-like storm (cyclone)).

Which statement best predicts why a cell's progression through the cell cycle might be halted by the G1/S checkpoint?

Answers

Answer:

The missing options are:

A. Spindle fibers have not correctly attached to chromosomes.

B. Damage occurred to DNA when it was being copied in G1.

C. There are not enough nucleotides available to construct new DNA.

D. Proteins necessary for M phase of the cell cycle have not been produced.

The correct option is C.There are not enough nucleotides available to construct new DNA.

Explanation:

During the G1 phase, the cell grows in size since it prepares its organelles and molecule combinations for the next phase of the cell cycle, the S phase. Before the cell transitions to the S phase, it has to pass through a checkpoint that makes sure that there are no mutations, it has grown enough, and has the necessary molecules for the next phase, which is the synthesis of DNA. If there are not enough nucleotides, the cell will not be able to synthesize new DNA in the S phase, so the checkpoint stops the cells from moving to this phase till it has all the necessary things to do it.
