Answer:

Looks like a recessive trait, since both halves of the shape needs to be filled to make the trait active.

The pedigree is explained in the image, and the male is represented by the square and the female is represented by the circle. Here is the sex linked recessive pedigree present in the image.

What does the pedigree explain?

The pedigree explains the heritable pattern of traits, such as genetic diseases in males and females, as well as the chances of being diseased, such as with sex-linked recessive diseases, where males have a higher chance of being diseased than females. Here the image explains it is a sex-linked recessive disease because most females are carriers, which means they have a single copy of the recessive allele, but when they pass it on to their sons, they get fully diseased as they need a single recessive copy due to the presence of a single X chromosome.

Hence, the male is represented by the square, and the female is represented by the circle, and here is a sex linked recessive pedigree present in the image.

Answers

I believe the answer would be aiding in digestion and extracting carbon dioxide from blood.

Explanation: Bone marrow production stops when a child reaches maturity. White blood cells are produced from bone marrow, and O red cells are produced from red bone marrow, leaving the only answer left by process of elimination as B. Kidneys are also responsible for keeping ph balance, sodium and electrolyte balance, along with the balance of other vitamins and minerals in the blood.

Summarize the weather and ecological conditions associated with each season?

Answers

Answer: Seasons have an enormous influence on vegetation and plant growth. Winter typically has cold weather, little daylight, and limited plant growth. In spring, plants sprout, tree leaves unfurl, and flowers blossom. Summer is the warmest time of the year and has the most daylight, so plants grow quickly. In autumn, temperatures drop, and many trees lose their leaves.

Most of the time in lichen, ascomycetes or basidiomycetes form the fungal part with several hyphae layers enveloping the photosynthetic algal part.

Lichens

Lichens are composite organisms. They are formed from a symbiotic relationship between fungi and algae. The fungi provide shelter and some vital minerals for the algae while the algae provide food via photosynthesis.

Oftentimes, the fungi components are usually ascomycetes or basidiomycetes. They form a network of hyphae around the photosynthetic algae as a form of protection.

Answer:

co dominance

Explanation:

codominance is a type of inheritance in which both allels are dominat over each other and the two allels are expressed to an equal degree in an offspring,that is why the cross between yellow and blue snake give another green colour offsprings in stead of giving all blue or all yellow offsprings depending on which allel is dominant.

as example we can take human blood group AB which is inherited from blood group A and B and both allel A and B are dominant over each other.

Energy in an ecosystem flows directly from _______. a. producers to tertiary consumers b. producers to secondary consumers c. tertiary consumers to secondary consumers d. secondary consumers to tertiary consumers please select the best answer from the choices provided a b c d

Answers

Answer:

A.

Explanation:

Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.

Energy in an ecosystem flows directly from producers to tertiary consumers. So, the correct option is A.

What do you mean by Ecosystem?

An Ecosystem may be defined as an area where organisms of different species are present together in a given time and interact with one another in order to survive.

In an ecosystem, producers produce the energy in the presence of sunlight through the process of photosynthesis. And then passes its energy to primary consumers (herbivores), then primary consumer passes their energy to secondary consumers (carnivores), then secondary consumers pass their energy to tertiary consumers. According to Lindeman, only 10% of energy get transferred to each trophic level.

Therefore, Energy in an ecosystem flows directly from producers to tertiary consumers.

Are heated air and wind shear the cause for severe storms? Explain.

Answers

Answer:

Yes, they are very much the main cause of severe storms because the heat molecules get into the atmosphere and clouds, causing chemical reactions and damage. At some point in time, the energy built up, as well as the damage done, must undo itself. This is done through a storm. It is the environment's way of cleaning itself.

As a part from this video below states, wind shear is a leading cause in severe storms.

List all the gametes that are possible with each of the following genotypes.
a. Aabb
d. AABb
b. AaBB
e. AAbb
C. AaBb
f. aabb

Answers

All the possible gametes for Aabb would be Ab and ab; that of AABb would be Ab and AB; that of AaBB would be AB and aB; that of AAbb would be Ab; that of AaBb would be AB, Ab, aB, and ab; and that of aabb would be ab respectively.

Gametes formation

The formation of gametes for a dihybrid involves the crossing of the two traits involved.

Thus: Aabb is equivalent to crossing Aa and bb

             

                           Aa   x   bb

                       Ab   Ab   ab   ab

Hence, all the gametes would be Ab or ab.

For AABb:                     AA   x   Bb  =   AB   Ab   AB   Ab

The gametes are either AB or Ab

For AaBB: the gametes are either AB or aB

For AAbb, only Ab gametes are produced

For AaBb: the gametes would be AB  Ab   aB and ab

For aabb: only ab gametes are produced.
