Explain spermatogenesis and oogenesis.

Answers

Answer 1

Answer:

yep, my explanation

Explanation:

you see, it is a very dirty cycle, when you have a dioploid cell, you have your typical duplication of sister chromotids, but producing sex cells or gametes which would become a zygote through dirty interactions come to form one dioploid cell and it will start doubling like the rest of the human body, until it comes out of the other human's body. meiosis, or the formation of gamates are created with a crossover where one diolpoid cell takes one half of the chromosome and the other half and exchange a tiny bit of it before splitting into 2 DIFFERENT gametes cells because of the cross-over and hence ther term natural selection

In an energy pyramid, up to 10% of energy is transferred between trophic levels. Suppose the producer level has 50,000 J. Approximately how much energy is available to the next level, the primary consumer, in this energy pyramid?

Answers

Answer: 5,000

Explanation:So it is the 10% law, this is an example 10,000 for the first animal, 1,000 for the second and 100 for the third. So for 50,000 it would be 5,000 for the next

What's the differences between species richness management approach and indicator species management way?

Answers

Answer:

Both have different function.

Explanation:

The main difference between species richness management approach and indicator species management way is that in species richness management we perform activities that allows increase in the population of species while on the other hand, indicator species are the organisms that provides information about the environment that is present in that ecosystem. Both has differences in their functions and their actions.

If you could genetically engineer any species of organism, what would it be? Would it be a unicorn? A
dog-cat hybrid? Your own personal pet giant? Choose any species--real or not--that your imagination
desires!
Write a paragraph describing your species, what it looks like, and where it lives. Think of any inherited
traits the species has that might help it survive in its environment. Thinking of these traits now can help
you come up with allele combinations in the next step. Now describe your species in the answer space.

Answers

Answer:

the species I would combine would be a trapdoor spider and a eel yeah its a unusual mix but at the same time it would be interesting to see because image a eel having 8 legs and spider fangs and armored skin it would most likely also be twice the size of a normal eel or even might have a mutation but who knows

What would happen if a populations chose their mates randomly?
A. Allele frequency would be constantly changing at random

B. The allele frequency would stay relatively the same over time because there are no traits that are being selected for.

C. Randomly mating allows the most beneficial traits to be passed on because more individuals are going to select for them.

D. Allele frequency would begin to favor the dominant trait.

Answers

Answer:

B. The allele frequency would stay relatively the same over time because there are no traits that are being selected for.

Explanation:

Like recombination, non-random mating can act as an ancillary process for natural selection to cause evolution to occur. Any departure from random mating upsets the equilibrium distribution of genotypes in a population. This will occur whether mate selection is positive or negative assortative.

Si el genoma de una especie contiene un 40% de la base timina, ¿cuál será el porcentaje de guanina del genoma de esta especie? 10% 35% 60% 30% 20%

Answers

Respuesta:

El porcentaje de guanina del genoma de esta especie será del 60%.

Explicación:

El genoma de todas las especies está compuesto por ADN (ácido desoxirribonucleico) bicatenario, lo que significa que tiene dos cadenas. Estas cadenas se unirán la una con la otra mediante un componente muy importante en los nucleótidos: las bases nitrogenadas que pueden ser de 4 tipos distintos: timina (T), guanina (G), adenina (A) y citosina (C). Los nucleótidos se aparean siempre de la misma manera para formar pares de bases: citosina con guanina (C-G) y adenina con timina (A-T). De esta manera, podemos inferir que si hay un 40% de base timina en el genoma de una especie, se unirá con un 40% de adenina, y el 60% restante serán pares C-G.

La respuesta correcta es entonces 60%.

Which term refers to the energy an object has due to its position?

Answers

Answer:

Potential Energy.

Explanation:

Potential energy, stored energy that depends on different parts of the system's relative position. When compressed or stretched, spring has more potential energy.

A stainless steel ball has more energy than it had when it fell to the world. It is able to do more work in the raised position.

Potential energy is a system's property and not a single body or particle. The earth-consistent system and raised ball, for instance, have greater potential energy as the two are more distinct.

Answer:

b . chemical weathering

Explanation:

Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.

When purified virulent pneumococci DNA was introduced to avirulent pneumococci, Avery and his colleagues observed _____. Multiple choice question. no death in test animals only growth of avirulent pneumococci, indicating DNA was NOT the agent of transformation death of test mice growth of virulent pneumococci, indicating DNA was the agent of transformation

Answers

Answer:

death of test mice, growth of virulent pneumococci, indicating DNA was the agent of transformation

Explanation:

In an experiment conducted by three scientists namely: Oswald Avery, Colin MacLeod and Maclyn McCarty in 1944, it was proven that DNA is the substance that causes transformation in bacteria as opposed to proteins.

In this experiment, Avery and his colleagues combined a dead but virulent strain of Streptococcus pneumoniae & a living but avirulent strain of the same bacterium and inserted into a living rat. They found out that the test specimen (rat) died and observed the growth of the virulent pneumococci.

This suggests that the virulent strain of bacteria has transferred its virulent DNA via transformation into the avirulent strain to kill the rat. Hence, indicating DNA as the agent of transformation.
