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

What additional restriction enzyme would be used to cut out another gene flanked by a different restriction site?
Answer:
a clone
Explanation:
Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences. Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, some produce blunt ends.

Which statement accurately describes how genetic information is transferred during meiosis?
Meiosis creates four daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates two daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates four daughter cells that have identical genetic information to the parent cells.
Meiosis creates two daughter cells that have identical genetic information to the parent cells.
Meiosis is the reductional division which creates four daughter cells that have identical genetic information to the parent cells. Thus, the correct option is C.
What is Meiosis?Meiosis is a special type of cell division which is also called as reductional division. This division takes place in the germ cells in sexually reproducing organisms which results into production of gametes, such as sperm or egg cells. Meiosis involves two rounds of division which ultimately result in the formation of four cells with only one copy of each chromosome or half genetic content.
Meiosis is divided into two divisions: Meiosis I and Meiosis II. In which, Meiosis II is similar to Mitosis and Meiosis I involves the reduction of genetic material to half.
Therefore, the correct option is C.

Explain why a high ratio of surface area to volume benefits a cell.
Answer:
smaller single celled organisms have a high surface area to volume ratio cause surface area to the volume ratio smaller as the cell grows larger. if a sell grow beyond the limit not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume
What are some of the WORST things about coal fuel?
help me please help me
Answer:
Explanation:
The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion. The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
Answer:
Air pollution
Can impact health of citizens like asthma, breathing difficulties, etc.
Can lead to death if not treated or fixed.
Releases greenhouse gases into the atmosphere.
Contributes to global climate change.

List 4 concepts you learned in this unit about waves and explain how each one applies to your life (4 points)
Answer:
amplitude, wavelength, frequency, and speed.
Explanation: Sound is a type of wave that moves through matter and then vibrates our eardrums so we can hear. Light is a special kind of wave that is made up of photons. You can drop a rock into a pond and see waves form in the water. We even use waves (microwaves) to cook our food really fast. Water waves are the focus of our Tsunamis and surf resources, but many other kinds of wave exist. These include sound waves, light waves, radio waves, microwaves and others. All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude.
Describe how the process of apoptosis occurs?
Answer:
Apoptosis is an orderly process in which the cell's contents break down and are packaged into small packets of membrane for “garbage collection” by immune cells. It contrasts with necrosis (death by injury), in which the dying cell's contents spill out and cause inflammation. Apoptosis removes cells during development.
Apoptosis is a form of programmed cell death that occurs in multicellular organisms.
What is apoptosis ?It is a natural biological process of programmed cell death in which the cells destroy themselves and maintain the smooth function of the body parts.
There are two types cell death such as Programmed death of cells or apoptosis and uncontrolled death or Necrosis.
Apoptosis can occur via two pathway such as Extrinsic Pathway is triggered in response to external stimuli, ligand binding at death receptor and these receptors are called as Tumor Necrosis Factor gene.
Intrinsic Pathway triggered in response to internal stimuli such as biochemical stress, DNA damage and this pathway is modulated Bax, and Bcl-2 molecules.
Apoptosis helps in maintaining homeostasis, proper size of the body, cell number, elimination of unwanted cell, T-lymphocytes etc.

Where does the mRNA go after it is produced?
Answer:
The mRNA goes after it is produced is made messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to one of the DNA strands of a gene. The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
Explanation:
mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes. Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide. Thus mRNA carries a “message” from the nucleus to the cytoplasm.
