Explanation:

pls mark brainliest

The male beetle must struggle to successfully mate with the female if where they go there is more than one male courting the female.

How do beetles mate?

Female beetles of this species dig tunnels in the dung, where males mate with them. If a male enters a tunnel that is already occupied by a rival, they will fight, trying to pull the other out.

With this information, we can conclude that the male beetle must struggle to successfully mate with the female if where they go there is more than one male courting the female.

When a scientist uses radiometric dating to determine the age of a rock specimen, would he use a radioactive element with a short half life, say a half-life of less than 10,000 years, or a radioactive element with a long half-life, say a half-life greater than 1 billion years?

Answers

Answer:

He will use a radioactive element with a long half life of greater than 1 billion years

Explanation:

Rocks are an aggregation of solid mass which is usually rich in minerals. The age of rocks is established using radiometric dating method.

According to Oxford Dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."

The age of rocks can only be ascertained using isotopes that have very long half lives because many of these rocks are very old (aged billions of years) hence their age can only be determined using elements that has a half life greater than 1 billion years.

HYPOTHESIS: If 2 chambers of water are poured side-by-side, the warmer water will mix the cooler layer because it

Answers

Answer:

The warmer water will mix with the cold water because it will migrate to the surface.

Explanation:

If hot water and cold water are poured in the same place, it means that they will occupy the same space. However, hot water has a lower density than cold water, which means that hot water molecules are lighter and will tend to rise towards the surface.

However, when migrating to the surface, the hot water molecules will pass between the cold water molecules, causing the two waters to mix. In this process, the hot water will transfer heat to the cold water and cool until the two waters have the same temperature.

Answers

Answer:

Directly affects.

Explanation:

Climate, resources, and habitat size directly affect  carrying capacity of an ecosystem. Favourable climatic and environmental conditions increases the population of organisms to its maximum limit. More resources leads to increase in population of species in an ecosystem until carrying capacity. Habitat size also depends on carrying capacity which means higher carrying capacity can leads to bigger habitat size. Climatic change, Habitat destruction, introduced and invasive species and genetic pollution are factors that effect both biodiversity and population. Human activities causes pollution, destruction of habitat by cutting trees etc affects biodiversity.

4) Ecological niche without competition

Answers

This situation is an example of 'ecosystems are ALTERED through the activities of humans' (Option 2).

Human activities (i.e., anthropogenic activities) represent the main factor capable of affecting the homeostasis of the ecosystems.

Some human activities that negatively alter a natural ecosystem include deforestation for different purposes (e.g., urbanization, agriculture, etc), the introduction of non-native invasive species, pollution, etc.

These activities may trigger serious problems to the environment such as soil erosion, climate change, undrinkable water, etc.

In conclusion, this situation is an example of 'ecosystems are ALTERED through the activities of humans'.

Answer:

The correct answer is - B. It moves out of the nucleus and into the cytoplasm.

Explanation:

mRNA formation is known as transcription which is the first process of protein synthesis in which mRNA is formed from DNA sequence with help of RNA polymerase enzyme.

After forming the mRNA sequence this mRNA moves out of the nucleus and reaches the cytoplasm where it performs the second process called translation with help of tRNA and ribosome to produce an amino acid chain.

Answer:

B. It moves out of the nucleus and into the cytoplasm.
