What are Gametes cells?
Answers
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.

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
Answers
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).

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
Answers
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.
the role of metal in oraganism
Answers
Answer:
Sorry if I'm wrong
Explanation:
Metals play very important roles in human life. Their absence may lead to several diseases in human body. Metals have also been exploited to design therapeutically useful drugs against several diseases like cancer, arthritis, ulcer, etc. Metals present in enzymes strongly facilitate their catalytic reaction.
The role of essential nutrient metal ions (Mg, Fe, Cu, Zn, Mn and Co) often deficient in our foodstuffs, although vitally essential in the function of the human organism as well as the different reasons for these deficiencies both in foods and in the human body have been studied.
Which statement best describes the relationship between an allele and a gene? hint - height has alleles of tall or short...
Answers
Answer:
See the answer below
Explanation:
A gene is made up of a pair of alleles that can be the same or different. When a gene is made up of the same allele, such gene is said to be homzygous and an individual is said to be true-breeding for that gene. When a gene is made of different alleles, such a gene is said to be heterozygous.
An allele, on the other hand, represents the alternate form of a gene. For example, height can be tall or short. Tallness represents one allele while shortness represents another allele. When the two alleles for a height are tall or short, it is homzygous, when it consists of one tall and one short allele, it is heterozygous.

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.
Answers
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.
A "TT" (tall) plant is crossed with at "tt" (short) plant. What percentage of the offspring will be tall?
Answers
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.
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
Answers
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.

A planet's gravity is related to which of the following?
mass and size
orbit
weight and density
surface area
Answers
Depending on the size, mass and density of the object, the GRAVITATIONAL force it exerts varies
xxx
The gravity of a planet is related to its mass and size. So, the correct option is (A).
What is Gravity?Gravity is a fundamental interaction caused by the mutual attraction between all things that have mass or energy. The force of gravity keeps all the planets in orbit around the Sun.
It is a property of matter where all the matter is attracted to all other matter. The more matter there is, and the closer the objects are to each other, the greater the force of attraction and unlike electricity and magnetism, which can either repel or attract, gravity always pulls things together.
The magnitude of gravity depends upon the mass of each object and the distance between the centers of the two objects along with the he weight of an object is determined by the pull of gravity on it.
Thus, the gravity of a planet is related to its mass and size. So, the correct option is (A).

A plant with narrow leaves and shallow roots would probably be found in the desert, where there is not a lot of water. Narrow leaves help prevent water loss. Shallow roots can spread out long distances in search of water.
Answers
Answer:
No.
Explanation:
The characteristic of narrow leaves is present in desert plants but shallow roots are not present because water is not available in the upper layer of soil due to faster leaching of water. Desert plants have deep root system which helps them to extract water from the deep layers of soil. Narrow leaves prevent transpiration of water from the plant body which helps the plant to store more water inside its body and remain turgor.
