Answer:
movement & calculations
Explanation:
The left side of the brain is responsible for controlling the right side of the body. It also performs tasks that have to do with logic, such as in science and mathematics.
On the other hand, the right hemisphere coordinates the left side of the body, and performs tasks that have do with creativity and the arts.
Answer:
calculations
movement
emotions
words and languages
Explanation:
emotions- "The neural system for emotions linked to approaching and engaging with the world – like happiness, pride and anger – lives in the left side of the brain, while emotions associated with avoidance – like disgust and fear – are housed in the right."
movement- "The primary motor cortex on the left side of the brain controls movement"
words and languages- "The left hemisphere is thought to control language, math and logic,'
Calculations- "The left lobe tends to deal more with numbers, letters, and symbols."

Which of the following is an example of selective permeability?
a magnet
a window screen
a milk jug
a bottle rocket
A window screen is an example of selective permeability.
• Selective permeability is a characteristic and function of the cell membrane, which plays an important role in sustaining homeostasis by monitoring the passage of certain substances while inhibiting others from invading the cell.
• Of the given options, a window screen is an example of selective permeability.
• A window screen is also known as the bug screen, insect screen, wire mesh, or fly screen is created to cover the window opening.
• It is generally a mesh formed of fiberglass, metal, pieces of plastics, plastic wire, and pieces of metal or wood.
• It functions to prevent the entry of bugs, birds, debris, and other animals into the building, however, it does not prevent the entry of fresh air.
Thus, a window screen is an example of selective permeability.

Every fall, Mrs. Rockel and her family rake over 100 bags of leaves. This year we raked only 60 bags, a considerable decrease compared to the past several years. Using your knowledge of the process of photosynthesis, construct a logical hypothesis to explain why.
Please help
Answer:
''Photosynthesis directly affect the vegetative growth of plants''
Explanation:
''Photosynthesis directly affect the vegetative growth of plants'' is the hypothesis that shows decrease occur in the bags of leaves. Photosynthesis is directly related to vegetative growth because Photosynthesis is a process of making food by using sunlight, this food is used by the plant to bear more number of leaves so if the process of photosynthesis is done properly, no decrease occur in the bags of leaves.

Read the scenario below and answer the questions that follow for 2 points each: Two Siamese and three Persian cats survive a shipwreck and are carried on driftwood to a previously uninhabited tropical island. All five cats have normal ears, but one carries the recessive allele f or folded ears, his genotype is Ff. The other four cats are not carriers, so their genotype is FF. Thus there are 10 total alleles within this population, 9 being F alleles and 1 being f. So, the frequencies are 9/10 or 0.90 for F the allele and 1/10 or 0.10 for the f allele. 1. Identify ONE of the five conditions required for Hardy-Weinberg equilibrium that this population of cats does not meet. 2. If you assume Hardy-Weinberg equilibrium for this population, what would be the frequencies of the two alleles after 10 generations? 3. Knowing that the frequency of the folded ears genotype ff is equal to to the frequency of the f allele squared (0.1 x 0.1), how many cats would have folded ears if after 10 generations there are 2,500 cats on the island?
Answer:
c
Explanation:
According to H-W, a population is in equilibrium if it meets five conditions, and have the same allelic and genotypic frequencies through many generations. 1) Infinite population size / 2) p=0.9 and q=0.1 / 3) 25 cats
-------------------------------------------------------
Let us review some theoretical framework about Hardy-Weinberg equilibrium, while we answer the questions.
⇒ Hardy-Weinberg assumption for a population in equilibrium:
Random matings No superposed generations No mutations No migration Infinite population size ⇒ No genetic drift No natural selectionQ1. Identify ONE of the five conditions required for Hardy-Weinberg equilibrium that this population of cats does not meet.
Since this population is composed of two Siamese and three Persian cats, the condition that this population does not meet is infinite population size.
This population is under the effect of genetic drift for being only 5 individuals colonizing an island.
*****************
⇒ According to Hardy-Weinberg, p and q represent the allelic frequencies in a locus, referring to the allelic dominant or recessive forms.
The genotypic frequencies after one generation are p² (H0m0zyg0us dominant), 2pq (Heter0zyg0us), q² (H0m0zyg0us recessive).
Populations in H-W equilibrium will get the same allelic frequencies generation after generation.
The sum of these allelic frequencies equals 1, this is p + q = 1. The genotypic frequencies sum also equals 1, this is p² + 2pq + q² = 1.
Being
p the dominant allelic frequency, q the recessive allelic frequency, p² the h0m0zyg0us dominant genotypic frequency q² the h0m0zyg0us recessive genotypic frequency 2pq the heter0zyg0us genotypic frequencyQ2. If you assume Hardy-Weinberg equilibrium for this population, what would be the frequencies of the two alleles after 10 generations?
Allelic frequencies, f(x), are
f(F) = p = 0.9f(f) = q = 0.1If this population is in H-W equilibrium, the allelic frequency will be the same through many generations.
So, after 10 generations, the allelic frequencies will still be p = 0.9 and q = 0.1.
Q3. Knowing that the frequency of the folded ears genotype ff is equal to to the frequency of the f allele squared (0.1 x 0.1), how many cats would have folded ears if after 10 generations there are 2,500 cats on the island?
We know that,
f(F) = p = 0.9f(f) = q = 0.1N = 2500 catsTo get the number of individuals with folded phenotype, we should get the phenotypic frequency, which equals the genotypic frequency because it is the recessive phenotype.
Genotypic and Phenotypic Frequency
F(ff) = q² = 0.1 = 0.01Now that we have the phenotypic frequency, we just need to multiply it by the total number of individuals in the population, N.
N = 2500 individuals
Individuals with folded ears = 0.01 x 2500 = 25So, after 10 generations and a population size of 2500 cats, there will be 25 folded-eared individuals.

Distinguish the steps involved in the impact theory of lunar formation.
The giant impact theory — the idea that a catastrophic collision about 4.5 billion years ago between Earth and a protoplanet about half Earth's size created a disk of molten rock, gas and debris that consolidated to form the moon — was first set forth in the mid-1970s.
The most normally invoked grounds for lunar formation maintain that a giant protoplanet is sometimes called Theia.
What is lunar formation?
When the Chemical differentiation and crystallization delivered dense material that sank to the bottom of the lunar magma ocean and a spirited crust that created the lunar highlands.
The numerous commonly invoked justification for lunar formation holds that a giant protoplanet, sometimes called Theia, struck the recently formed Earth 4.5 billion years heretofore and formed a cloud of debris that fast coalesced into the moon.
But that hypothesis has mourned from a nagging flaw. Simulations of moon-forming crashes have shown Theia would have stood as the immediate donor of lunar material.
But commentaries of Apollo moon rocks have authenticated that the moon appears in many ways a chemical clone of Earth, not Theia.
