Answers

Answer:

They reproduce sexually.

Explanation:

They exhibit multiple traits and grow quickly.

One of the reasons why Gregor Mendel chose to study pea plants is because they reproduce se-x-ually

Gregor Mendel's study of pea plant

In Gregor Mendel's work on pea plants, he discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Parental genes are randomly separated to the reproductive cells so that s-ex cells contain only one gene of the pair

2. The main reason for this difference is the altitude: while Minsk is located at 280 meters over the sea level, Banff is located at approximately 1400 meters over the sea level. As the altitude is higher, the average temperature is lower.

3. Jakarta: in fact, it is located at a similar altitude of Kuala Lumpur (just in the opposite hemisphere), in the equatorial zone, while Baltimore is located much more north, so in a colder region.

4. Because they are located at approximately same latitude (just in the opposite hemisphere), so they are more or less same distance from the equator, and they receive more or less same amount of sun light, therefore they have similar climate.

Answers

Answer:

The hours are the independent variable.The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .The domain is 0 to 30 The range is 0 to 330

Explanation:

The hours are the independent variable and  should be plotted on the x-axis .

The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked )  and should be plotted on the y-axis

---------------

Let +W+ = wages/wk earned

Let +h+ = hours/wk worked

The equation is:

+W+=+11h+

The domain is 0 to 30

( no hrs worked to 30 hrs worked )

The range is 0 to 330

( no wages eared to +11%2A30+=+330+ earned )

Which is not a benefit of maintaining sustainable forest ecosystems?
Select one:
O a. Empty space on which to build homes
b. Habitat for thousands of species
c. Reduction of erosion in watersheds

Answers

The correct answer as to which is not a benefit of maintaining sustainable forest ecosystems would be empty spaces on which to build homes.

An ecosystem refers to a network of communities interacting together as a unit. A forest ecosystem, therefore, is a community of different plants, animals, and microbes interacting together and with their physical environment as a unit.Sustainable forest ecosystem is a system of managing forest resources in such a way that the ecological processes and functions provided by the forest do not depreciate. The ecological functions of forest ecosystems include the provision of foods, drugs, and raw materials for man, protection of watersheds,  provision of habitats for other species, and playing important roles in the stability of climates.

Hence, not maintaining forest ecosystems in a sustainable way means that some of the functions they perform such as the provision of habitats for species and reduction of erosion in watersheds would be lost.

The only option that is not a benefit of maintaining sustainable forest ecosystems is A.

How does coral reef damage negatively affect the land? a.) There is more biodiversity. b.) There is a loss of cures. c.) There is more land erosion.

Answers

Answer:

The answer would be C

Coral reef damage negatively affects the land primarily by causing a loss of cures. Hence the correct option is B.

1. Loss of cures: Coral reefs are incredibly diverse ecosystems that provide numerous ecological and economic benefits. One significant impact of coral reef damage is the loss of potential cures and medicinal resources. Many marine organisms, including those found in coral reefs, contain bioactive compounds that have the potential for developing new medicines, treatments, and therapies. By damaging coral reefs, we risk losing these valuable resources and potential cures for various diseases.

2. Biodiversity decline: While option A, "There is more biodiversity," is incorrect in this case, it is important to note that coral reefs are known as the "rainforests of the sea" due to their high biodiversity. Coral reefs support a wide range of marine species, providing habitats, shelter, and food sources. When coral reefs are damaged, either through human activities like pollution, overfishing, or climate change-related factors like coral bleaching, the biodiversity of the reef ecosystem decreases.

3. Land erosion: Option C, "There is more land erosion," is not typically a direct consequence of coral reef damage. However, healthy coral reefs do play a role in protecting the coastline from erosion. Coral reefs act as natural barriers that help dissipate the energy of waves, reducing wave-induced erosion and protecting nearby coastlines from storms and wave action. When coral reefs are damaged or destroyed, the protective function of the reef is lost, potentially leading to increased erosion of the nearby land.

Hence the correct option is B
