Gregor Mendel crosses a true-breeding tall plants (TT) with a true-breeding short plant (tt). What are the predicted phenotypes for the offspring ?

a. all tall
b. all short
c. ratio of 1 tall : 1 short
d. ratio of 3 tall : 1 short

Answers

Answer:

a. all tall:

Explanation:

Tall plants (TT) are the more dominate trait. Use the Pundett square (I will try to recreate it as best as possible but it will not look good):

     t       t

T  Tt      Tt

T   Tt     Tt

As you can (kind of) tell, T appears on all offsprings, and as the dominate trait, it will take over 100% of the time.

The next generation (depending on who you are breeding them with), will have a different result.

How does light behave?

Answers

When light moves from one medium (like air) to another medium (like water) it will change directions. This is a "wave-like" behavior and is called refraction. In this way light behaves like other waves such as sound waves.

Answer: Light behaves like waves, they undergo reflection, refraction and diffraction just like any other wave would.

Explanation:

Light waves move and change direction all the time. But how can we compare them? to all other waves because this behavior happens constantly.

Biodiversity
Genetic engineering
Bioremediation
Hemodialysis
NEED HELP ASAP PLEASE

Answers

Answer:

Option B, Genetic engineering

Explanation:

Biodiversity determines the different types of species living in a given area. Hence it is incorrect

Bioremediation is basically a waste management system in which organisms are used to break down hazardous substances into less toxic substances. Hence, it is also incorrect

Hemodialysis is used to remove or filter out wastes and water from blood. Hence, it is also incorrect  

Genetic engineering is used to produce organism with desired trait by altering their DNA and hence the associated Phenotype. Thus, it is the correct answer

Hence, option B is correct

Answer:

Genetic engineering

Explanation:

Genetic engineering is a technique in which DNA of desired gene is isolated from the body of an organism and inserted into the body of host cell. The host cell then develop organism or species with the characteristics of desired gene. The organism with genetic manipulation are called genetically modified organism (GMO).

Genetic engineering has many application such as human growth hormones, mass-produce insulin, follistim (for treating infertility), monoclonal antibodies,  increasing productivity of animals and plants et-cetra.

Some animals are unable to breed or produces organism due to genetic diosrders or mutaions, with the help of genetic engineering a DNA with gene of interest can be inserted in the host or animal cell, which will treat or remove the natural barries and will make enable it for breeding.

Hence, the correct answer is Genetic engineering.

A student in genetics class is studying the inheritance patterns in fruit flies. He is looking at the traits for wing length, long versus short, and colorbrown versus gray. Using a dihybrid cross of two flies that were heterozygous for long wings and brown color. Long wings and Gray are dominant. How many offspring will have long wings and brown color?

Answers

Answer:

LLgg, Llgg , two out of 16

Explanation:

Given,

Dominant - Long wings and Gray color

Recessive - Short wings and Brown color

Let the allele for long wings be "L" and the allele for short wings be "l".

Let the allele for brown color be "g" and allele for gray color be "G"

Genotype of parents

LlGg

Gametes of the parent

LG, Lg, lG, lg

Dihybrid cross is between LlGg and LlGg

The offspring produces will be as follows -

LG        Lg         lG         lg

LG LLGG LLGg LlGG LlGg

Lg LLGg LLgg LlGg Llgg

lG LlGG LlGg llGG         llGg

The ultrasound is considered safe because it uses sound waves for the detection of tissue, organ, baby etc. These waves are considered safe and transfer only a small amount of heat to the tissue in which the ultrasound is done. A little amount of heat is not at all harmful to the body in any means. Early defects of baby can be detected through this procedure, the merits of the process is much higher than its demerits.

Answers

D because they evolved into the special that are current now

Fossils of species that no longer exist but are ancestors of current species have been found in rock layers. Thus, the correct option is D.

What are Fossil fuels?

A fossil fuel is a hydrocarbon-containing material which is formed naturally in the Earth's crust from the remains of dead organisms such as plants and animals which are extracted and burned as a fuel. The main fossil fuels which are present in the earth's crust include coal, oil, and natural gas.

The evolution of species is easily confirmed by the presence of fossils of the most diverse species of the living beings in the world. This is because, fossils are the records of species which do not currently exist, however there are existed millions of years ago and are similar to the current species, being their ancestors.

Therefore, the correct option is D.
