"Could you please help me? I have a question that is honestly NOT a homework

question. I am a Junior here at LTHS. "Could a man with type B blood and a

woman with type AB produce a child with type O blood?" I think not, because

type O is recessive, and the B's seem to be dominant. My cousin thinks yes.

Thank you for your help."

Answers

Answer 1

It is not common but yes an ab parent can have an O child

Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. parent. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.

What data provides the strongest evidence (most valid) that early Earth conditions provided what was necessary for life?
A- Fossil evidence showing that prokaryotic cells required an environment free of oxygen.
B- Genetic comparisons revealing that living and extinct organisms share commonalities.
C- Geological dating techniques supporting theories regarding Earth's age.
D- Geological studies proving that volcanic gases resemble those from early Earth.

Answers

Answer:

A - Fossil Evidence showing that prokaryotic cells required an environment free of oxygen.

Explanation:

Thanks OP for answering your own question!

The data that provides the strongest evidence (that is, the most valid evidence) that early Earth conditions provided what was necessary for life is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.

What are genetic comparisons in evolution?

Genetic comparisons are the most direct and reliable source of evidence supporting the theory of common ancestry and the origin of life on Earth. All living organisms share a common set of genetic building blocks, such as DNA and RNA, and use the same genetic code to translate this information into the proteins that make up living organisms. Genetic comparisons reveal similarities between living organisms and extinct organisms, such as ancient bacteria and archaea, which provides further evidence for the common ancestry of all life on Earth.

Hence, it is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.

➜ Mendel conducted breeding experiments with garden peas:

[i] He studied plants (pure) of a tall/short varities.

[ii] He crossed them and obtained F1 progeny.

[iii] He found that F1 progeny was all tall plants.

[iv] He selfed the (hybrid) plants if F1 progeny.

[vi] The three quarter plants were tall and one quarter was short.

(or any other contrasting character may be taken).

Note: Here, F1 means First fillial generation and F2 means Second fillial generation.

Mendel selected garden pea for his breeding experiment because of its contrasting characters such as height of the plant, yellow or green seed, round or wrinkled seed shape. ... Then he allowed the hybrid plants of F1 generation to self-pollinated. In F2 generation all the progeny were tall as well as short plants...We used to take this character, we may choose different.

2. Explain the relationship between genetic variation and an organism's ability to adapt to its environment,

Answers

Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.

Answers

➜ Speciation is the formation of new species from the pre-existing population.

Factors responsible for speciation:

Genetic drift. Natural selection.Geographical isolation. Mutation.

Geographical isolation cannot be a major factor in the speciation of a self-pollinating plant species because physical barrier cannot be created in self-pollinating plants.

Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.

We call objects of this kind transparent. Clear glass and clear plastic wrap are two transparent objects. Other objects, such as wax paper or frosted glass, let some light through but scatter or block the rest. These objects are translucent. Then there are opaque objects, which do not let any light through. Opaque objects block all light. Instead, they produce shadows on a surface when an object prevents light from reaching that surface. You are an opaque object. So is a wooden door, a refrigerator, or a moose.SoundSound travels in waves that are produced when something vibrates. Sound waves are invisiblewe cannot see the movement of sound through the air with our eyes. Unlike light, sound needs a medium, something to travel through. Sounds can move through solids like walls or clothing, liquids such as water, or gases such as air. Walls, water, and air are all examples of different media through which sound travels.Both paragraphs describe how a type of energy moves, or travels. How are the structures of the paragraphs alike?

If you know Spanish well can you help me with rewriting the command in the affirmative or the negative usted form At the beginning of 2019, the Healthy Life Food Company purchased equipment for $42 million to be used in the manufacture of a new line of gourmet frozen foods. The equipment was estimated to have a 10-year service life and no residual value. The straight-line depreciation method was used to measure depreciation for 2019 and 2020. Late in 2021, it became apparent that sales of the new frozen food line were significantly below expectations. The company decided to continue production for two more years (2022 and 2023) and then discontinue the line. At that time, the equipment will be sold for minimal scrap values. The controller, Heather Meyer, was asked by Harvey Dent, the company's chief executive officer (CEO), to determine the appropriate treatment of the change in service life of the equipment. Heather determined that there has been an impairment of value requiring an immediate write-down of the equipment of $12,900,000. The remaining book value would then be depreciated over the equipment's revised service life. The CEO does not like Heather's conclusion because of the effect it would have on 2016 income. "Looks like a simple revision in service life from 10 years to 5 years to me," Dent concluded. "Let's go with it that way, Heather." Required: What is the difference in before-tax income between the CEO's and Heather's treatment of the situation? Discuss Heather Meyer's ethical dilemma.
