In shorthorn cattle, when a red bull (RR) is crossed with a white cow (WW), all the offspring are roan—a spotted, red and white color. What offspring are expected from mating a roan bull and a roan cow?
Answer:
25% red
50% roan
25% white
Explanation:
When RR (red) is crossed with WW (white), it results in roan color.
RR (red) x WW (white)
RW (roan)
Two roan individuals are then mated.
RW x RW
RR RW RW WW
Offspring
1/4 RR - Red
1/2 RW - Roan
1/4 WW - White
Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.
A mutation that could be inherited by offspring would result from-?
Answer: Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences. Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation.
Explanation:
A mutation that could be inherited by offspring would leads from a base substitution in gametes during meiosis. The correct option is D.
What is mutation?Any alteration to a cell's DNA sequence. Alterations in cell division can result in specific mutations.
As can exposure to environmental DNA-damaging substances. Mutations may be negative, positive, or ineffective.
Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
A base substitution in gametes during meiosis would result in a mutation that might be passed on to progeny.
Thus, the correct option is D.

Artificial selection has produced a wide variety of crop plants, livestock, and pets. Which characteristic of artificial selection makes it different from natural selection
Answer:
Genetic Problems
Explanation:
When people genetically modify animals, they can mess up a lot of their natural abilities. For example in some cases scientist have made cows who produce more milk, but couldn't reproduce anymore because of it. Sometimes it even hurts the animal. People have bred dogs in certain ways that makes it hard for them to breathe, like Bull dogs who has respiratory issues. This makes decreases their life span and continuing to bred them will only make it worse. When scientist have a certain trait they want they also make animals breed with their own families. Incest creates a lot of genetic problems.

What is ethylene oxide?Ethylene oxide may be defined as a type of highly flammable gas that is significantly utilized in order to sterilize medical equipment. It is a colorless gas with a sweet odor.
It is used primarily to produce other chemicals, including antifreeze. In smaller amounts, ethylene oxide is used as a pesticide and a sterilizing agent.
As this ethylene oxide is a highly flammable gas one must be required to keep this in a place or an area that is free from sparks or any other kinds of flames.
Therefore, to prevent a fire hazard, ethylene oxide should only be used in an area without sparks or flames. Thus, the correct option for this question is D.

Students are conducting a lab estimating the time it takes for the cell cycle in normal chicken cells. They find that the average time for one complete cell cycle is 22 hours.
What differences would they expect to see in cancerous chicken cells?
A Cancerous chicken cells will spend more time in interphase.
b Cancerous cells will not complete all phases of the cell cycle.
c Cancerous chicken cells will complete mitosis in a shorter amount of time.
d Cancerous chicken cells and normal cells will have the same total time to complete the cell cycle.
Answer:C!
Explanation:
Cancerous chicken cells will complete mitosis in a shorter amount of time.
The difference they would expect to see in cancerous chicken cells is cancerous chicken cells will complete mitosis in a shorter amount of time. The correct option is c.
What are cancerous cells?Cancerous cells are those cells that cause cancer in organisms. These cells are the converted form of normal cells. The normal cells are converted into cancerous cells by the means of mutagens.
The cell cycle is the cycle of the division of a cell. The cell divides itself and forms a new daughter cell. That's how a body increases the older cells to divide and produce new cells. The process is called mitosis.
Now, the normal cells divide at a constant and normal rate that is needed, but the cancerous cells divided abnormally and rapidly which cause tumor in the body.
Thus, the correct option is c. Cancerous chicken cells will complete mitosis in a shorter amount of time.

Answer:
The answer is option A "Is True"
Explanation:
The Monarch is notable for its capacity to travel significant stretches, and the migrations in North America are one of the best common marvels on the planet. This butterfly is additionally periodically recorded from the English Isles, making it our biggest and most extraordinary traveler butterfly.
Each fall, a great many ruler butterflies move 3,000 miles from their favorable places in northeastern North America to spend the colder time of year in the timber lands of southwestern Mexico. Every movement is by new generation, so they can't gain from others. All things being equal, they depend on their qualities. Their antennae have a genetic clock that reveals to them when to move and to explore they measure the sun's situation not too far off with their eyes.

b. lack of pollinating insects
c. higher initial costs
d. increased erosion
e. increase labor costs
Answer:
I think its A and E
Explanation:
^^^^^^
The challenges to implementing sustainable farming practices: higher initial costs; increase labor costs.
What is sustainable agriculture?It is an integrated system which includes both plant and animal farming practices, which hence has a minimum effect on the environment. It involves using substances of natural origin and hence meets the needs without causing an adverse impact on the environment.
What are its advantages?It prevents pollution since the waste remains in the farm's ecosystem.There is a reduction in the production of waste, and the waste of one is used in the other.It saves energy as there is a lower requirement for non-renewable resources.It doesn't use agrochemicals.It involves methods that reduce soil erosion, like managing irrigation, covering the soil with tillage.What are its disadvantages?It takes more effort since the use of machines is minimal.Limited use of land and hence, mass production is not possible.What are the challenges?New farmers have to struggle with high labor demand since it involves less use of machines and hence more workers are required.Before harvesting their first crop, young farmers require a huge sum of up-front capital, which is even more for biologically diverse farms.Hence the correct options are (c) and (e) higher initial costs; increase labor costs.
