What is the function of the Cornea?
Answer:
The function of the cornea is it acts as the eye's outermost lens. It functions like a window that controls and focuses the entry of light into the eye. The cornea contributes between 65- 75 percent of the eye's total focusing power.
Explanation:
A balloon full of helium slowly deflates. What best explains why the balloon shrinking is an example of a physical change?
The helium has changed state from gas to liquid.
Helium never undergoes chemical reactions.
A physical property of the helium gas, the volume, has changed.
Helium has physically escaped from small holes in the balloon.
Answer:
A physical property of the helium gas, the volume has changed.
Explanation:
its an example of physical property because the substance is being removed and the form of the balloon is changing.
What events cause exhalation?
Answer:
The process of exhalation occurs due to an elastic recoil of the lung tissue which causes a decrease in volume, resulting in increased pressure in comparison to the atmosphere; thus, air rushes out of the airway. There is no contraction of muscles during exhalation; it is considered a passive process.
Explanation:
The fact that imprinting is most certain to occur if the opportunity for imprinting is presented to the organism at a very specific age indicates the existence of
Answer:
a critical period
Explanation:
In developmental psychology and developmental biology, a critical period is a maturational stage in the lifespan of an organism during which the nervous system is especially sensitive to certain environmental stimuli(Wikipedia). It is a time during early postnatal life when the development and maturation of functional properties of the brain, its 'plasticity', is strongly dependent on experience or environmental influences(Sengpiel, 2007).
The fact that imprinting is most certain to occur if the opportunity for imprinting is presented to the organism at a very specific age indicates the existence of a critical period in the life of organisms.
13. Write the amino acid chain for the following DNA sequence:
AGTCGCTATTAGCCG
a. Serine-Alanine-Isoleucine-Isoleucine-Glycine
b. Serine-Arginine-Cysteine-Stop
c. Arginine-Leucine-Isoleucine-Alanine-Threonine
d. Alanine-Valine-Cysteine-Arginie-Threonine
Answer:
a. Serine-Alanine-Isoleucine-Isoleucine-Glycine
Explanation:
This question is describing gene expression, which comprises of transcription and translation. Transcription is the process by which a DNA molecule is used as a template to synthesize a mRNA molecule while in translation, the mRNA is used to synthesize an amino acid sequence using a set of three nucleotide bases called CODON in the mRNA.
According to this question, the following DNA sequence is given: AGTCGCTATTAGCCG. The process of transcription will form the following mRNA sequence from this DNA sequence: UCAGCGAUAAUCGGC.
Translation will make use of the genetic code to produce the following amino acids. Note that, one codon e.g UCA encodes an amino acid (serine).
The amino acid sequence is: Serine-Alanine-Isoleucine-Isoleucine-Glycine.
UCA codes for Serine
GCG codes for Alanine
AUA codes for Isoleucine
AUC codes for Isoleucine
GGC codes for Glycine
If 70% of the alleles in a gene pool of a population are dominant, the frequency of the
Answer:
Explanation:
The number of copies of an allele in a population divided by the total number of all alleles for that gene in a population is the allele frequency. For a gene with two alleles whose frequencies are p and q, the Hardy-Weinberg equation states that the genotypes that are possible for the population are p^2 + 2pq + q^2, which is equal to
The dandelion is a successful weed. Explain why its adaptations make it a better competitor than many other plants on a school field or a garden lawn.
Answer:
The correct answer is - dandelion weeds adapted many tricks to reduce all other competitors as it is invasive species.
Explanation:
The dandelion is a successful weed. It's got a lot of adaption to eliminate or dominate other plants and weeds, such as ethylene gas released by its rosette of leaves that prevent other plants from growing near dandelion.
Seeds of dandelion also adapted seed dispersion tactic by seed-parachutes into the wind. Dandelion weed does not require to be pollinated and rapidly increases their numbers. Dandelion has a taproot that goes deep into the soil, up to three feet down for water and nutrients.
which steps of the greenhouse effect are most affected by the increases in greenhouse gases, leading to increase in heat?
Answer: Greenhouse gases arise naturally, and are part of the make-up of our atmosphere. Earth is sometimes called the “Goldilocks” planet – it’s not too hot, not too cold, and the conditions are just right to allow life, including us, to flourish. Part of what makes Earth so amenable is the naturally-arising greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average. But in the last century or so, humans have been interfering with the energy balance of the planet, mainly through the burning of fossil fuels that give off additional carbon dioxide into the air. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth, causing temperatures to rise.

What is a natural selection? (use your OWN words and make it short)
Answer:
Natural Selection is the way that animals survive and adapt, which means that heritable traits that increase survival chances in a certain species are passed down to their offspring and over generations, certain things that species may have died to don't affect them anymore.

how much body parts does a blue whale have ?
Given that the diploid number of cattle is 60 (2n = 60) how many pairs of chromosomes do cattle have?
Answer: 30
Explanation:
Diploid is simply referred to as a cell or an organism which possess paired chromosomes. The paired chromosomes are gotten from each of the parents.
It should be noted that the total chromosomes that will be found in the cattle's somatic cell is 60. Therefore, the pair will be 60/2 = 30.

If DNA read A-T-T-A-C-G-G-C-C what would the RNA read? Why is DNA replication important?
If DNA read A-T-T-A-C-G-G-C-C the RNA would be U-A-A-U-G-C-C-G-G
DNA replication is important because new cells require their own strand of the DNA. Without replication, there would be no new organisms because the DNA’s information would not be passed on.

I need help with dominant and recessive genes, it doesn't really make sense to me can sombody explain how it works?
Answer:
Dominant: the genes that are expressed/ shown
Recessive: the "hidden" genes
Explanation:
If one parent has a dominant gene for brown eyes and the other has a recessive gene for blue eyes, then the offspring will have brown eyes.
Hope this helps!
You can message me if you are still confused.
Explanation:
dominant genes will always appear before recessive ones, in order for recessive genes to appear, both copies of the gene have to be the recessive one tldr for this paragraph, think of dominant genes like jackets, and recessive ones like t shirts
an example
B=brown hair gene (dominant)
b=blond hair gene (recessive)
this is an example of 2 parents, with offspring
Bb Bb <-- both parents have a copy of brown and blond hair gene, but since dominant genes appear before recessive ones, they both have brown hair
now, lets look at their possible offspring genes
BB Bb Bb bb
in order, their hair color will be
brown, brown, brown, blond
see the last one? the only reason why that child is blond is because they don't have a brown hair gene tldr of this paragraph, recessive genes will only be present if both copies of the gene is the same
with the first example, lets say its a cold day. what would you wear, a jacket or a t shirt? a jacket, obviously
but what if you only had t shirts? then you would be forced to wear that and think about your poor freezing self...
pretend the T shirt is blond hair gene, and jacket is brown hair
and the closet only holds 2 clothes
2 domiant genes will do the same thing, brown hair
1 domiant gene and 1 recessive will use the domiant gene, since domiant genes get used first, like brown hair will show even though you have a copy of blond hair gene
2 recessive genes, and only then will the recessive show, like blond hair
uwu wow this took way too long to type

In peas, long stem (A) is dominant over short stem (a). A heterozygous, long stem plant (Aa) is crossed with a homo-zygous, short stemmed plant (aa).
Which of the above squares represent plants that are heterozygous?
Question 9 options:
Box 1
Box 1 and box 2
Box 1 and box 3
Box 2 and box 3
Answer:
Box 1 and box 3
Explanation:
[tex]\huge\boxed{\textbf{Box 1 and Box 3}}[/tex]
_____________________________________[tex]\Large\textbf{Phenotype:}[/tex]
It is the physical appearance of the trait, whether the plant has Long stem or short stem.
[tex]\Large\textbf{Genotype:}[/tex]
A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or h o m o-zygous, recessive or dominant. This question is basically based on the Genotype, asking for the heterozygous plants which is a genotypic characteristic.
_____________________________________Alleles:Allele Long stem A is dominant over short stem a
Genotype of Parent Pea PlantsPea Plant 1 has genotype Aa
Pea Plant 2 has genotype aa
_____________________________________[tex]\Huge\text{Question:}[/tex]The question asks for how many heterozygous plants are present in the punnet square of pea plant 1 and pea plant 2.
Heterozygous PlantsHeterozygous Plants means those plants which have two different alleles that means One dominant allele (i.e. A here) and One recessive allele (i.e. a here). These Organisms inherit a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one.
If we look at the punnet square given in the attachment, the Box 1 and 3 have genotype Aa which is a HETEROZYGOUS DOMINANT PLANT while box 2 and 4 have a genotype aa which is a HOMO-ZYGOUS RECESSIVE PLANT thus the answer is Box 1 and 3
