How has climate influenced the size of house sparrows? a. They have gradually become smaller in colder parts of the country.
b. Their size has not changed in response to climate.
c. They have gradually become larger in colder parts of the country.
d. Their size has increased in response to heavy rainfall.

Answers

Answer 1

Answer:

The study of living things is called biology. There are two types of living are these are plants and animals.

The correct answer to the question is A that is They have gradually become smaller in colder parts of the country.

What is climate?

Climate is the long-term weather pattern in an area, typically averaged over 30 years.
More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years.

According to the question, the size is directly proportional to the temperature of that given area. Colder the climate smaller the organism and vice versa. This statement is given by Allens and is known as Allens rule

Hence, the correct answer is option A.

Answer 2

Answer:
I think its C because if they became larger, it would help them to hold more heat.

When an object is burning, two atoms of oxygen (in the air) combine with one atom of carbon (from thesubstance burning). This forms carbon dioxide gas. Explain how the law of conservation of matter applies to

this reaction.

2. A piece of wood is burned, and a small amount of ashes are formed. Explain why the original piece of wood

and the resulting ashes will not weigh the same.

Answers

1. The law of conservation of mass applies to this reaction because when you look at its balanced chemical equation, the same amount or ratio of elements can be found:

C + O2 --> CO2

This shows that the product will have the same ratio of reactants.

2. The original piece of wood and resulting ashes do not weight the same because the combustible parts of the wood were burned and converted to gases. This means that the missing mass is equal to the gases produced. The remaining ashes are the incombustible parts of the wood.

What is expected to happen to the death rate as population density and competition increase?a. decreases
b. increases
c. remains the same

Answers

Answer: a. decreases

Explanation:

A population density can be define as the number of individuals in a population of a species living in a unit of area in a particular time. The population density can be influenced by number of births, deaths, immigration, emigration and competition. The number of live birth in a concerned population and immigration (introduction of the new members) are likely to increase the population density of a region. But the number of deaths and emigration (the members of the same population move to a new habitat), and the competition (the members of the same species may compete among themselves for the same resources, the superior one will receive the resources and the inferior one will loose and may die) will decrease the population density.

According to the given situation, death rate and competition among the individuals will likely to decrease the population density.

As the population density increases therefore we probably have an increase in birth rate, aslo less space becomes available to individuals and if competition increases that means we probably have an increase in fighting (contest competition) therefore there might be an increase in individuals dying. Therefore I would say the answer is (c) the increase in population density would cancel out the competition. Hope this helps :).

What is one of the differences between the erosion of riverbeds and the erosion of glaciers?The riverbed erodes into an L-shaped valley, whereas the glacier erodes into a W-shaped valley.
The riverbed erodes into a U-shaped valley, whereas the glacier erodes into a V-shaped valley.
The riverbed erodes into a V-shaped valley, whereas the glacier erodes into an L-shaped valley.
The riverbed erodes into a V-shaped valley, whereas the glacier erodes into a U-shaped valley.

Answers

The correct statement is the fourth one. The riverbed erodes into a V-shaped valley while the glacier erodes into a U-shaped valley. Glaciers and rivers have tributaries or small rivers that join the main river. For glaciers, as it erodes deeper, the small river is left higher up the steep sides. For rivers, as it erodes, ridges of land form in its upper course.

Cuckoo bird relationship with a warbler

Answers

Cuckoos are commonly known for brood parasitism, meaning that they lay their eggs in other birds' nests and leaving the unfortunate mother of that nest to care for the invader baby. Sometimes, the cuckoo would even remove the mother's eggs to ensure that the invader baby bird would get the most care and food.

So a cuckoo bird's relationship with a warbler would be that of parasitism. At the very least, it's harmful for the warbler.
