What factors affect the likelihood a species will migrate from the mainland to an island?

Answers

Answer:

The factors that might affect the likelihood a species will migrate from the mainland to an island are the distance to the mainland and the island´s size.

Explanation:

Ecologists MacArthur and Wilson took the term island biogeography theory to refer to the predictions about the number of species that could inhabit an island.  

Island biogeography theory establishes that the two factors that affect species richness in natural communities on an island are the distance to the mainland and the island´s size.

At the same time, these factors affect immigration and extinction rates. According to the theory, islands that are closer to the continent have higher possibilities of receiving immigrants than those located farther from the mainland. This is the effect of distance.

The effect of size is reflected in the relation between island size and species diversity.  In smaller islands, the probability of extinction is higher than in bigger islands. Bigger islands can have more species than smaller ones.

In the case of two islands of the same size and different distance to the mainland, both of them will have the same extinction rate, but the one closer to the continent will have a higher immigration rate, and so, a higher amount of species. The S value will be higher on the island closer to the continent.

Which action is most likely to stop succession and make an ecosystem less
stable?
O A. Using fewer pesticides in gardens
B. Using less fertilizer in gardens
C. Planting a variety of native species in gardens
D. Planting nonnative species in gardens

Answers

The answer is D.  Because planting nonnative species is bad for the area because the plants that normally grow there have to compete with that new species then.  

Answer:

D. Planting nonnative species in gardens.

Explanation:

Planting nonnative species in gardens are bad for your garden. The nonnatives can steal most to all of your native plants food and they can attack your native plants and kill them.

A peony plant with straight stamens and red petals was crossed with another plant having straight stamens and streaky petals. The seeds were collected and germinated and the following offspring were obtained 62 straight stamens with red petals 59 straight stamens, streaky petals 18 incurved stamens, red petals 22 incurved stamens, streaky petals a) Which alleles in each pair are dominant

Answers

Answer:

Explanation:

From the given information.

Let the Straight stamens be S;

The incurved stamens be s;

The red petals be R; and

The streaky petals be r

The genotype of the parental plants are Straight stamens, red petals (SsRr) and Straight stamens, streaky petals)

So if SsRr and Ssrr crossed together, Then we have the following:

If SsRr self crossed, we have the following traits  = SR  Sr sR sr; &

Ssrr = Sr Sr sr sr

Then, the dihybrid cross is:

               

           SR               Sr                      sR                     sr

Sr       SSRr             SSrr                  SsRr                 Ssrr

Sr      SSRr             SSrr                  SsRr                 Ssrr

sr      SsRr              Ssrr                  ssRr                 ssrr

sr      SsRr              Ssrr                  ssRr                 ssrr

P(Straight stamens, red petals) = 8/16

P(Straight stamens, streaky petals) = 6/16

P(Incurved stamens, red petals ) = 2/16

P(Incurved stamens, streaky stamens) = 2/16

Answers

Answer: Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea.

After some testing, the doctor tells them there is no chance that either of them will ever have a child with type O blood, no matter their partner. He does assure them that all of their children will have the same blood type. On the other hand, none of the children will have the same blood type as either the mother or the father. What blood type will the children be?

The blood type that the children won't have O blood type because the doctor says so and the children will not have the same blood type. This means that the children's blood type will likely be type A or Type B.

how does a birds digestive system work?ФΔФ

Answers

From the bill, food moves down a tube called the esophagus and into the crop, which stores excess food so the bird can digest it slowly. The food then moves to the proventriculus, which is the first part of the stomach, where it is softened by gastric acid, mucus, and other digestive juices.

Answer:

Birds have a two part stomach, a glandular portion known as the proventriculus and a muscular portion known as the gizzard. Hydrochloric acid, mucus and a digestive enzyme, pepsin, are secreted by specialized cells in the proventriculus and starts the process of breaking down the structure of the food material.

Describe: Fossil fuels are used in many ways. Using the Gizmo, describe the main use for each fuel.


Coal:



Petroleum:


Natural gas:

In each case, what is the end product of burning the fossil fuel, and where does it go?

Answers

Answer:

Coal:

Coal is primarily used as fuel to generate electric power

Petroleum:

heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials

Natural gas:

heating, cooking, and electricity generation.

it all end up in the atmosphere

Explanation:

The coal is burned and the heat given off is used to convert water into steam, which drives a turbine.

petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria.

Like oil, natural gas is a product of decomposed organic matter, typically from ancient marine microorganisms, deposited over the past 550 million years. This organic material mixed with mud, silt, and sand on the sea floor, gradually becoming buried over time.

Coal and natural gas are burned in power plants to boil water. Steam from boiling water converts turbines into electricity. Carbon dioxide from burning fuel is released into the atmosphere.

This is about description of fossil fuels which are simply fuels that are formed from natural processes.

       The uses and end products of fossil fuels are talked about in the explanations below;

1) (I) The primary use of the fossil fuel named coal is to generate electricity.

          ii) When coal is burnt, it produces a very high heat. This heat is so high that it converts water into high-pressure steam. What drives a turbine is a high pressure steam and this drive makes the turbine to produce electricity.

2) I) Petroleum products are used to set vehicles in motion, for asphalt on roads, production of electricity and heating of buildings.

           II) when petroleum is burnt to create energy, it produces high amount of carbon dioxide and other toxic gases into the atmosphere that can cause greenhouse effect.

3) I) Natural gas is used primarily as a source of energy for cooking, generating heat and for providing electricity.

           II) When it undergoes combustion is produces large amount of carbon dioxide and nitrogen oxides into the atmosphere.
