Answer:
The correct answer is: the nervous system, brain, and eyes.
Explanation:
Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are long-chain polyunsaturated fatty acids that have great nutritional value, as they are omega-6 and omega-3 fatty acids, respectively, meaning they are essential fats that cannot be produced by the body and, therefore, need to be part of the diet.
The consumption of ARA and DHA has been directly linked to the development of the brain and the retina, and the inclusion of these fatty acids in the nutrition of infants has been proven to be extremely beneficial to their growth.
Besides their functions in the development of the nervous system and the eyes, ARA and DHA play a role in maintaining a healthy immune system and preventing cardiovascular conditions.
Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are two long-chain fatty acids necessary for the development of the nervous system, brain, and eyes.
Arachidonic acid (ARA) and docosahexaenoic acid (DHA) represent two long-chain polyunsaturated fatty acids.In mammals, these polyunsaturated fatty acids (ARA and DHA) are fundamental during the development of the nervous system, and they are found in milk.It is for that reason that in some countries DHA and ARA nutrients are added to the milk formulas used to feed babies.In conclusion, arachidonic acid (ARA) and docosahexaenoic acid (DHA) are two long-chain fatty acids necessary for the development of the nervous system, brain, and eyes.

Which statement correctly describes a feature of the rock cycle?
O Rocks are preserved through the process.
O Rocks change from one type to another.
O Different rock groups are not related to one another.
O Rocks change from one type to another in a specific order.
Answer:
The correct description of a feature of the rock cycle is:
O Rocks change from one type to another.
Explanation:
Sedimentary, metamorphic, and igneous rocks are the three main rock types. Together, they form the universal rock cycle. A sedimentary rock, for example, can change from its known state to another state by passing through crystallization, metamorphism, erosion, and sedimentation. There are no specific orders for the change. The processes that they pass through determine the resulting type.
Answer:
Rocks change from one type to another.
Explanation:
How can embryos be more useful than adults to show evolutionary relationships among organisms?
Select one:
Related organisms always appear identical in embryonic stages.
Adults may have mutations that are not found in embryos.
Evolutionary relationships are more easily observed in more simple organisms.
Features found in embryos may not be found in adults.
Answer:
Related organisms always appear identical in embryonic stages.
Explanation:
Embryos of organisms that have a closer genetic relationship to one another tend to look similar for a longer period of time since they share a more recent common ancestor. Thus, embryology is frequently used as evidence of the theory of evolution and the radiation of species from a common ancestor.

What is Climate Change?
Explain your answer.
What is Climate Change?
Climate change is a change in the usual weather found in a place.
How it helps us:
Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures. ... We can also see which regions are most likely to be affected by extreme weather, or which wildlife species are threatened by climate change.
How it works:
As the earth's atmosphere heats up, it collects, retains, and drops more water, changing weather patterns and making wet areas wetter and dry areas drier. Higher temperatures worsen and increase the frequency of many types of disasters, including storms, floods, heat waves, and droughts.
How it affects us:
Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats.
Which of the following will most likely result if all of the primary consumers are removed from this ecosystem?
Answer:
Secondary consumers will lower in numbers and the producers (plants) will be overabundant.
Explanation:
Okay so secondary consumers eat the primary consumers and the primary consumers eat the producers (plants). If there are no primary consumers, there is no one eating the plants which will lead to the producer population growing because there's less stopping them from growing in numbers. The secondary consumers will be in trouble because the secondary consumers don't eat plants. If there are no primary consumers, the secondary consumers won't be able to eat and the numbers of secondary consumers will decrease.

How is mitosis different in plants and animals?
Answer:
The main difference is cell plate formation and how they form the daughter cells during cytokinesis. In plants, they lack centrosomes. A new cell plate will form between the daughter cells for the future cell wall. In animal cells the cell membrane will rather constrict to separates the parent cell into the daughter cells. Plants also do not undergo cell furrowing, unlike animals cells.
what are the interactions between atoms that are hydrolyzed by fungi to release nitrogen from these molecules?
birth defects due to radiation are a concern also. why is a fetus especially at risk?
Of the babies that survive, however, few will have birth defects related to the exposure, regardless of how much radiation they were exposed to. Large radiation doses to the fetus during the more sensitive stages of development (between weeks 2 and 18 of pregnancy) can cause birth defects, especially to the brain.

A strain of a cereal grain can be either dark tan, medium-dark tan, medium tan, light tan, or cream colored. When a dark tan and a cream plant are crossed, all F1 are medium tan. The F2 are distributed in a ratio of 1:4:6:4:1 from darkest to lightest. How many genes are involved in this coloration?
Answer:
The correct answer is - 2 genes.
Explanation:
The number of genes involved in the coloration of the strain of cereal grain, could be either dark tan, medium-dark tan, medium tan, light tan, or cream-colored if all F1 are medium tan when crossed a dark tan crossed with cream-colored, can be calculated as follow:
suppose there are only two gene - TT dominant over tt and CC dominant over cc
then the cross would be - RRCC - rrcc
gametes - RC and rc
Cross F1: RrCc
Self cross in F2:
offspring by Punnet cross are:
RRCC -->1/16
RRCc, RrCC .---> 4/16
RrCc, RRcc, rrCC--->6/16
rrCc, Rrcc--->4/16
rrcc ----> 1/16
thus, the correct answer is 2 genes

How did the development of sexual reproduction affect evolutionary change?
Can someone tell me if this is correct I need help with the percentage
Answer:
Hand = 75%
No hand = 25%
Explanation:
It's the same thing as last time. Since 3 of them are heterozygous and have 1 dominant allele, they have the dominant trait. And since one of them only has recessive alleles then it should have the recessive traits.
So the hand should have 75% and no hand has 25%.

g Neuron A and neuron B interact with neuron C. Neuron A will produce an IPSP of -2mV in neuron C; neuron B produce an EPSP of 3mV in neuron C. The resting membrane potential is -70mV and the threshold is -50mV. Neuron A fires 6 times rapidly at the same time that neuron B fires 4 times rapidly. What is the resulting membrane potential in neuron C
Answer:
-70 mV
Explanation:
Given that Neuron A and Neuron B interact with Neuron C
Neuron A produces ; - 2mV of IPSP and fires 6 times
Neuron B produces ; 3mV of EPSP and fires 4 times
Resting potential = - 70mV
threshold = - 50mV
The resulting membrane potential in neuron C
= -70 + 6(-2) + 4(3)
= -70 - 12 + 12 = -70 mV

According to the diagram how are the three components
of a nucleotide important to the structure of DNA?
Answer:
A nucleotide of DNA is made up of three parts: a nitrogenous base, a 5-carbon sugar, and a phosphate group. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
The phosphate group linked with deoxyribose sugar to make the framework for the nitrogenous bases. The phosphate group and sugar molecule make the DNA backbone and support it. These backbones hold nitrogenous bases and make a monomer of DNA. Nitrogenous bases make DNA stable and hold both backbones together. These bases also make DNA functional.

Answer:
100% of the offspring would be black fur, black eyes (16/16)
Explanation:
(Because the info. wasn't included here, I'm assuming black fur and black eyes are dominant, BBEE, to the recessive white fur and red eyes, bbee)
For BBEE x bbee, you'd create a typical dihybrid true-breeding punnett square , where the first top row would be BE , BE, BE , BE , and the vertical/side row would be be, be, be, be.
Cross these alleles as you would typically for any punnett square, and you'd see that all the offpsring would result in BbEe genotypes, which is true of any true-breeding dominant x recessive cross, which always results in the dominant phenotype being 100%.
So...
Black Fur and Black Eyes : 16/16 (100%)
Black Fur and Red Eyes: 0/16
White Fur and Black Eyes: 0/16
White Fur and Red Eyes: 0/16
