What are Gametes cells?
Answer:
I think Gametes are mature male or female reproductive cells that fuse together resulting in a zygote during sexual fertilization. The key difference between somatic cells and gametes depends on the ploidy of the genome. Somatic cells consist of diploid (2n) genome while gametes consist of a haploid (n) genome.
Hope it help you!:)
Answer: Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.

Which environmental factor would cause the greatest decrease in the number of species of plants and animals living in some of the lakes in the United States
Answer:
Which environmental factor would cause the greatest decrease in the number of species of plants and animals living in some of the lakes in the United States is acid rain
Acid rain refers to the precipitation of acidic components from the atmosphere to the Earth's surface. Some of the most common acidic components are sulfuric acid and nitric acid.
The ACID RAIN is the environmental factor that causes the greatest decrease in the number of species of plants and animals living in lakes in the USA.The negative ecological effects of acid rain are higher in aquatic environments (e.g., streams and lakes) than in terrestrial environments.In aquatic environments, it has been shown that acid rain decreases biodiversity by changing the pH level of lakes and streams.Acid rain can directly or indirectly affect different aquatic species (both plants and animals), thereby distorting the food chain and thus altering all trophic levels.In conclusion, ACID RAIN is the environmental factor that causes the greatest decrease in the number of species of plants and animals living in lakes in the USA.

Energy is produced in the cores of main sequence stars when?
A) lighter elements undergo fusion into heavier elements
B) heavier elements undergo fusion into lighter elements
C) cosmic background radiation is absorbed
D) cosmic background radiation is released
Answer: A
Explanation:
The fusion between 4 hydrogens (H) nuclei into a helium (He) atom releases the energy in main-sequence stars. In the Sun, it produces by proton-proton chain reactions.
Energy is produced in the cores of main-sequence stars when lighter elements undergo the fusion into heavier elements (Option A)..The proton-proton (p–p) chain occurs in stars that have a core temperature of less than 15,000,000 Kelvin degrees.The p--p chain consists of three (3) reactions that convert six (6) protons into a He nucleus with 2 residual protons. This process releases energy.In conclusion, energy is produced in the cores of main-sequence stars when lighter elements undergo the fusion into heavier elements (Option A).

A "TT" (tall) plant is crossed with at "tt" (short) plant. What percentage of the offspring will be tall?
Answer:
100%
Explanation:
My biology teacher taught me the FOIL method. F=first, O=outside, I=inside, and L=last.
TT x tt
The first letter of each parent together would be Tt, T=tall so the plant would be tall, 25%
The outside letter of each parent together would be Tt, T= tall so the plant would be tall, 25%
The inside letters of each parent together would also be Tt, T=tall so the plant would be tall, 25%
The last letter of each parent together would also be Tt, T=tall so the plant would be tall, 25%
Each outcome has a T, and that is dominant so therefore, the plants will always be tall. You could also think about it as a letter has to be passed down to each child and the first plant only has capitals to pass and the second only has lowercase to pass down.
100% of the offspring will be tall.

Answer:
presence of the placenta (mammals)
Explanation:
Cat and dogs are two species that belong to the group of placental mammals (class Mammalia). Some phenotypic traits that are exclusive of mammal species include, among others, mammary glands, presence of hair or fur, sweat glands, specialized teeth, etc. A phylogenetic tree is a representation of the evolutionary relationships among different groups/taxa. Moreover, cats and dogs represent two different species of placental mammals, which are characterized by the presence of the placenta (an organ that facilitates the exchange of nutrients during gestation). In this case, the remaining two branches in the phylogenetic tree (branches from left to right) separate from more closely related to less closely related taxa that diverged from the same ancestral node.

To generate a knockin mouse, a scientist introduces to ES cells a construct with a mutant exon and within an adjacent intron, loxP sites flanking a neomycin resistance gene. What event will occur next?a. Crossing of heterozygous mice to a Cre-expressing strain.b. Homologous recombination between the mutant DNA and the corresponding gene in the mouse genome.c. Recombination between the loxP sites.d. Transplantation of cells into host blastocyst.
Answer:
b. Homologous recombination between the mutant DNA and the corresponding gene in the mouse genome
Explanation:
The Cre-lox recombination system is a versatile mammalian gene-editing tool used to produce site-specific recombination events in specific cell lines (e.g., embryonic stem or 'ES' cell lines) by facilitating the integration of a circular molecule in genomic DNA. This system makes use of a Cre recombinase enzyme from bacteriophage P1 that has the ability to recombine specific sequences referred to as Lox sequences. By using this system, it is possible to generate knockout mice by crossing a strain of mice expressing Cre recombinase strain with a targeted loxP-flanked (floxed) mouse strain. The generation of a floxed mouse consists of 1-generation of a targeting construct containing homologous sequences with the mouse genome and loxP sites flanking the gene sequence of interest, and 2-homologous recombination of the targeting construct with the endogenous target gene sequence in the mouse genome.

When doing a two-trait cross, the genotypes of the parents require how many letters? A) one B) two C) three D) four
Answer:
D) four
Explanation:
When doing a dihybrid cross, it's assumed that there is two alleles for each gene. Two traits requires two genes, and two genes requires four alleles, or "letters"
The genotypes of the parents require ( D ) : Four
A two-trait cross ( dihybrid ) is a cross between 2 individuals who are heterozygous at 2 loci
example of a two-trait cross
dihybrid cross between Tall plants with Brown flowers
genotype for each plant ( heterozygous ) = TtBb
Therefore the cross = TtBb * TtBb
where : T ( tall ) = dominant
t ( dwarf ) = recessive
B ( brown ) = dominant allele
b ( white ) = recessive
Hence the parents genotypes will require 4 letters ( TtBb * TtBb )

Which statement about AMP and energy is true? 1. AMP releases energy as it makes ATP 2.AMP absorbs energy when it breaks bonds 3.AMP releases energy when formed 4.AMP has one phosphate molecule
Answer:
The correct answer is - 4. AMP has one phosphate molecule.
Explanation:
AMP or adenosine monophosphate is the secondary messenger and major component of ATP (the cellular energy form). As suggested by the name it has only one molecule of phosphate, unlike ADP that has two and ATP where three phosphates are attached to one sugar molecule and nucleobase adenine.
AMP has the least energy in comparison to the ADP and ATP as more energy releases when bonding breaks. It is interconverted to ADP and ATP in metabolic processes.
