If a dog bladder cell has 100 chromosomes, how many will be in a dog egg cell?

Answer:

It can be a number of factors that can cause a population to grow. It can depend based on the birth rate, death rate, immigration, and emigration of the species. Additionally, it can also be how well the species adapts to it's environment.

hope that helps :-)

D. Meiosis forms four cells all with different genetic material

Explanation:

They are haploid cells and each cell only had one set of chromosomes. Meiosis results in variation.

Primary succession occurs after the occurrence of a severe event that leaves nothing but rocky surfaces. Option B. Lichens will grow on the cooled lava.

The succession term refers to colonization and subsequent changes.

Colonization has been defined as the sequence of events that conduce to the establishment of individuals, populations, species, or bigger groups in areas where they were absent before.

Succession refers to changes produced in the composition and structure of communities after a perturbation. There are different grades of succession according to the perturbation intensity.

In primary succession, the perturbation is so intense that it eliminates all the life forms in the area.

It is the sequence of species appearance in an exposed area that has not been influenced by any other species or community before.

In these cases, the rock gets exposed but it can not be colonized directly. The new area needs to suffer erosion and different chemical and physical processes that fragment, degrade and dissolve the rock to make colonization possible.

Primary succession occurs after severe events affecting a region, such as a retreating glacier, a volcanic activity, or an intense fire that leave nothing but the exposed rock.

After the disturbance, the order of the living beings establishment depends on the strategies of each of the species to survive.

First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space.

Pioneers modify the habitat. They make it more suitable for the posterior establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses.

Grasses and pioneers keep modifying the ground and making it better with time.

Habitat modification keeps on going while new species establish. They produce shadows and alter the temperature, and humidity, fertilizing the soil.

Competition becomes more frequent between species. The first species are eventually eliminated by competition, while new species keep appearing and competing for resources.

This sequence continues until there is no more facilitation, and the communities reache a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.

In the exposed example, the severe event affecting the Hawaii's Big Island was a volcanoe eruption.

The most likely event observed first in the areas covered by lava would be Lichens will grow on the cooled lava. Option B

Answer: Codons

Explanation: Three neighboring nucleotides form a unit known as the codon.

Answer:

5

Explanation:

The object distance Is 20 I'm

The image distance is 6.666

Therefore the focal length can be calculated as follows

1/f = 1/20 + 1/6.66

= 6.66+20/133.2

= 26.66/133.2

1/f= 26.66/133.2

f = 133.2/26.66

= 4.99

= 5

Hence the focal length is 5

Aloe vera, Christmas cacti, neem, orchids, and other plants can be found in the lithosphere.

The solid outer layer of Earth is known as the lithosphere. The Earth's outermost layers, the crust and the brittle upper part of the mantle, are together referred to as the lithosphere.

The asthenosphere, another component of the upper mantle, and the atmosphere form its boundaries.

Lithosphere Together, the upper mantle and crust make up the outermost layer of the planet. The lithosphere is home to a variety of plants, including aloe vera, Christmas cacti, neem, orchids, and others.

The lithosphere includes a wide variety of animals. There exist microorganisms, underground organisms, animals that live on the ocean floor, as well as land animals including tigers, lizards, and moles.

Thus, these are the plants that lives in lithosphere.

Yeah the kids will most likely be brown the phenotypes would be Bb (heterozygous dominant)

Answer:

This would be an example of nonpoint source pollution.

Explanation:

The source of point source pollution is typically factories and powerplants, leading to more air and water transferred pollutants and becoming easier to track. Nonpoint source pollution is the opposite of point-source pollution, with pollutants being released in a wide area. Since the rainwater would be washing the oils and particles into the water, it would be considered runoff. Runoff is one of the leading causes of point source pollution. I hope this helps. ^_^

Answer:

I think, the egg. Not so sure about it.

Eggs come from chickens and chickens come from eggs: that’s the basis of this ancient riddle. But eggs – which are just female sex cells – evolved more than a billion years ago, whereas chickens have been around for just 10,000 years. So the riddle is easily solved…or is it?

Taken at face value, there is no doubt that the egg came before the chicken. We tend to think of eggs as the shelled orbs laid by birds from which their chicks hatch – unless we eat them first. But all sexually reproducing species make eggs (the specialised female sex cells). That’s 99.99 per cent of all eukaryotic life – meaning organisms that have cells with a nucleus, so all animals and plants, and everything but the simplest life forms.

We don’t know for sure when sex evolved but it could have been as much as 2 billion years ago, and certainly more than 1 billion. Even the specialised sort of eggs laid by birds, with their tough outer membrane, evolved more than 300 million years ago.

As for chickens, they came into being much later. They are domesticated animals, so evolved as the result of humans purposefully selecting the least aggressive wild birds and letting them breed. This seems to have happened in several places independently, starting around 10,000 years ago.

The wild ancestor of chickens is generally agreed to be a tropical bird still living in the forests of Southeast Asia called the red junglefowl –  with other junglefowl species possibly adding to the genetic mix. From these origins, humans have carried chickens around the world over the past two millennia or more.

So, eggs dramatically predate chickens. But to be fair to the spirit of the riddle, we should also consider whether a chicken’s egg predates a chicken. As humans consistently chose the tamest red junglefowls and bred them together, the genetic makeup of the resulting birds will have shifted. At some stage during this domestication process the red junglefowl (Gallus gallus) evolved into a new subspecies, Gallus gallus domesticus, AKA the chicken.

In practice, it is impossible to pinpoint the moment when this happened. But in theory, at some point two junglefowl bred and their offspring was genetically different enough from the species of its parents to be classified as a chicken. This chicken would have developed within a junglefowl egg and only produced the very first chicken’s egg on reaching maturity. Looked at this way, the chicken came first.

Explanation:

The main concern of using nuclear power is the radioactive elements it creates. An example would be uranium.

Sure natural gas is bad for the environment but its no where near as harmful as exposure to radioactive

Drilling for oil does not release radioactive elements therefore exposure to radioactive elements can only be caused by nuclear power.
