Purple is dominant to white. A flower with the alleles PP (purple) is
crossed with a flower with alleles pp (white). What is the percent chance
that their offspring (babies) will be purple?
0%
50%
100%
Answer:
100% P is dominate there for all matches will be Pp this mean it will either be purple or a mixture of both (pink)
Explanation:
Which of the following environmental parameters would be important to monitor in order to ensure sustainable logging?
A. The number of trees cut down versus number trees burned
B. The number of new trees planted to replace those removed
C. The number of trees needed to increase soil fertilization
D. The number of trees removed within a single species
Answer:
B. The number of new trees planted to replace those removed
Explanation:
Because to ensure that logging is sustainable, they have to sustain a certain ratio of trees cut down, to trees planted. D. The muber of trees removed within a single species could be right, but I think B is more right.
If you get this wrong you can blame it on me.
Answer:
The number of new trees planted to replace those removed
Explanation:
Desert plants and animals are adapted to the lack of what and high
Answer:
lack of water and high concentration of heat and dryness
Explanation:
Deserts don't get that much rainfall, so desert wildlife are adapted to survive in such a dry climate. Take the camel, for instance, it can store three bathtubs of water in it's hump, so it can go a very long time without water. And without that rainfall, the desert is dry and, usually, very hot. Animals have adapted to this by only coming out in the nighttime when it's cooler.

During science class, Sofia drew a picture similar to the one above. Which phrase would appear in the caption box on the right side of the figure?
Group of answer choices
low sound
long wavelength
short wavelength
low frequency
Answer: low sound
Explanation:
plz help me i beg of you!???
Answer:
Pretty sure it's D, because the birds beak evolves to crush those grains as a result of certain food available in their habitat, although it does not say "diet" as an option so D is your best guess.
Explanation:
If two hybrid tall pea plants are crossed what is the probability that the offspring will have the tall phenotype?
Answer:
There is a high probability that the Pea plant will have a High phenotype!
Explanation:
Because both "parent plants" are tall, this will cause the offspring to also be tall, this will be because it in it's genes or in other words DNA too be strong.

What might be the consequences of your choice?
• Political:
• Economic:
• Social:
Answer:
Political: Lobbyists.
Economic:Farmers and industrial companies will significantly reduce their output and reduce local jobs. The companies that sell pesticides and fertilizers to local companies will also suffer losses. Farmers will suffer the most if they are unable to find safer fertilizers and pesticides to use.
Social:After a period of time, water pollutants will reduce to safe levels. This could be a long wait. Poverty may increase in the region due to lost jobs and income.

When equipment malfunctions, a(n) _____ needs to be initiated.
A) Notification
B) Paper Work
C) Alarm
D) Work Order
Answer: Alarm
Explanation:
When equipment malfunctions, an alarm should be initiated to bring the malfunction to the attention of the relevant personnel.
This will ensure that whatever adverse effects the malfunction could have caused is mitigated and the machine can be attended to on time to prevent further damage.
what is the dakota access pipeline
Answer: The Dakota Access Pipeline (DAPL) or Bakken pipeline is a 1,172-mile-long underground oil pipeline in the United States. It begins in the oil fields of the Bakken formation in northwest North Dakota and continues through South Dakota and Iowa to an oil terminal near Patoka, Illinois.
Explanation:
true or false:
Fish are considered carbon-based organism
Answer:
Its how you see it.
Explanation:
1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.
2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.
In those parts of equatorial Africa where the malaria parasite is most common, the sickle-cell allele constitutes 20% of the b hemoglobin alleles in the human gene pool. In the United States, the parasite that causes malaria is not present, but African-Americans whose ancestors were from equatorial Africa are present. What should be happening to the sickle-cell allele in the United States, and what should be happening to it in equatorial Africa
Answer:
directional selection, stabilizing selection
Explanation:
Directional selection is a type of natural selection that favors one extreme phenotype over other phenotypes, thereby modifying allele frequency in the direction of the favored phenotype. This type of positive selection is the main cause of phenotypic diversification. In the USA, the environment created a selection pressure that favored individuals that don't have the defective sickle-cell allele, thereby reducing its frequency in this population. Stabilizing selection, also known as balancing selection, is a type of natural selection where the most common phenotype is selected in the population, thus predominating in future generations. In equatorial Africa, the defective sickle-cell allele is present in a high frequency because individuals that are heterozygous for this allele are less susceptible to malaria, and therefore balancing selection should maintain this allele in the African population.

from his monohybrid crosses, Mendel developed his first law
Answer:
Im confused but if your asking for Medel's first law it would be states that for the pair of alleles an individual has of some gene (or at some genetic locus), one is a copy of a randomly chosen one in the father of the individual, and the other if a copy of a randomly chosen one in the mother, and that a randomly chosen one will be copied

Which atom is involved in giving your heart energy to beat?
O carbon
O gold
O oxygen
O iron
Answer:
Oxygen
Explanation:
-How fast the heart beats depends on the body's need for oxygen-rich blood. At rest, the SA node causes your heart to beat about 50 to 100 times each minute. During activity or excitement, your body needs more oxygen-rich blood; the heart rate rises to well over 100 beats per minute.
-The heart, like any organ, requires blood for oxygen and other nutrients so it can do its work. The heart does not gather oxygen or nutrients from the blood flowing inside it. Instead, it receives blood from coronary arteries that eventually carry blood into the heart muscle.

Answer:
A and B
Explanation:
1. A dominant gene (A) causes yellow color in rats, the dominant allele on another independent gene (R) produces black coat color. When the two dominants occur together (A_ R_) they interact to produce gray coat color. Rats of the genotype aa are cream-colored. If a gray male and a yellow female, when mated, produce offspring approximately 3/8 of which are yellow, 3/8 gray and 1/8 cream, and 1/8 black, what are the genotypes of the parents
Answer:
Parents: Yellow (Aarr) and Grey (AaRr)
Explanation:
Given:
allele A = yellow
allele R = black,
Heteroozygous = gray
Genotypes of the parents:
yellow (Aarr) - female
gray (AaRr) - gray
cross between these
Parents: Yellow (Aarr) and Grey (AaRr)
Gametes: (Ar, ar) and (AR, Ar, aR, ar)
F1 (Punnet square)
----|----- AR ------|------- Ar ------|------ aR -----|----- ar
Ar | AARr (gray) | AArr (yellow) | AaRr (gray) | Aarr (yellow)
ar | AaRr (gray) | Aarr (yellow) | aaRr (black) | aarr (cream)
Ratio: 3/8 yellow : 3/8 gray : 1/8 cream : 1/8 black
