When an offspring receives one green allele (G) and one red allele (R), the result id a green leaf with red veins

Answers

Answer:

GR

Explanation:

the genotypes of the parents are homozygous dominant GG and RR so when they fertilise they give all GR offsprings

The genotype of the plant is GR. This is because the offspring received green allele (G) as well as red allele (R), and both results showed up as the plant is green with red veins.

When something gives up alleles to its offspring, the parents originally have alleles like Aa and Bb. When offspring is created, you can use the Punnett square to guess which alleles will be passed on. In the plant’s case, G and R were passed on.

How do animals and plants play a role in the water cycle?

Answers

Answer:

Plants, especially trees, contribute to the water cycle via transpiration, where water evaporates from the surface of their leaves. Close to 10 percent of all water enters the water cycle due to plant transpiration. Animals contribute to the water cycle via respiration, perspiration and urination.

Explanation:

The also known as the or the , describes the continuous movement of water on, above and below the surface of the Earth. During this process, water changes its state from one phase to another, but the total number of water particles remains the same.



Without the water cycle, freshwater lakes and rivers would not exist and living things would not be able to thrive on land far from the ocean. do not just benefit from the water cycle -- they participate in it. The contributions of living organisms to the water cycle are vital.




Plants, particularly trees, contribute greatly to the water cycle because of the processes they use to . Unlike animals, which get their energy from food, plants convert sunlight into usable energy through photosynthesis. Plants also and through their roots.

When a tree absorbs water, it travels throughout its branches to its leaves. Needed for photosynthesis, trees and plants cannot get the energy they need from the sun without water. During photosynthesis, some excess water from the surface of the leaves, becoming water vapor. The water vapor in the process of travels into the atmosphere and becomes part of the water cycle, in the same way as evaporated water from lakes, rivers and oceans.

At first glance, it may not seem that plant transpiration contributes that much to the global water cycle. But plants and trees supply a large amount of the world's water via this process. About 10 percent of all water enters the cycle via plant transpiration.




Though they don't contribute as much as plants, animals still supply some of the water present in the water cycle. Animals contribute water mainly through , .

When animals breathe, their warm lungs fill with air. Inside the lungs, some of that air condenses into water vapor. When an animal exhales, they release more water vapor than they breathed in, which adds to the water present in the water cycle. Many animals also . When droplets of sweat evaporate from the surface of an animal's skin, they take a bit of the animal's body heat with them. They also turn into water vapor and enter the water cycle, just like water evaporating from plant leaves.

When animals consume water, they to expel the excess, which then then evaporates and re-enters the water cycle. Even animal dung contains some water which may re-enter the cycle in the same way. Though trees represent the biggest living contributors to the water cycle, animals also play a valuable role in recycling Earth's water. Without living creatures, the water cycle’s effectiveness diminishes, and less water recycles. Though often not included in the explanation of the water cycle, all living organisms contribute to it in their distinctive ways.

What are the four main types of Global wind? Describe its characteristics for each one.

Response:

ChatGPT

The four main types of global wind are:

Trade Winds: Trade winds are prevailing winds that blow from east to west between the equator and 30 degrees latitude in both the Northern and Southern Hemispheres. They are called "trade winds" because historically they were used by sailors for trade routes. Trade winds are generally steady and reliable, and they play a significant role in shaping weather patterns and ocean currents in tropical regions.

Westerlies: The westerlies are prevailing winds that blow from west to east between 30 degrees and 60 degrees latitude in both hemispheres. These winds are influenced by the Earth's rotation and are generally stronger and more variable than the trade winds. The westerlies are responsible for weather patterns in mid-latitudes, including the movement of storms.

Polar Easterlies: The polar easterlies are cold prevailing winds that blow from east to west near the poles (around 60 degrees latitude) in both hemispheres. These winds are characterized by their cold temperatures and high latitudes. They are relatively weak and variable due to the smaller temperature differences at the poles.

Polar Front Jet Stream: The polar front jet stream is a fast-flowing, narrow air current that flows from west to east in the upper troposphere, generally along the boundary between the Ferrel and Polar cells. It is strongest in the winter and weaker in the summer. The polar front jet stream plays a crucial role in the formation of weather systems and can influence the tracks of storms.

It's important to note that these wind patterns are influenced by various factors, including the rotation of the Earth, the distribution of land and water, and temperature differences between different latitudes. The interaction of these factors creates the complex global wind patterns that drive weather systems and climate around the world.

The sun heats up water and causes it to evaporate, the evaporated water then turns into clouds and once enough water has evaporated the clouds become heavy due to gravity and precipitates or in other words form water droplets once again that fall from the sky (Rain). The process then repeats as the water cycle.

State the steps of Darwin’s theory of evolution starting with Speciation as step 1.

Answers

In fact, we may distinguish five theories that Darwin combined: evolution as such, common descent, gradualism, multiplication of species, and natural selection.
Actually, Speciation is not the first step in Darwin's theory of evolution. It is one of the outcomes of the evolutionary process. However, I will provide you with the correct sequence of steps in Darwin's theory of evolution:

Variation: Individuals within a population vary in their traits.
Inheritance: Some of the variations are heritable and can be passed on to offspring.
High rate of population growth: Populations have the potential to produce more offspring than the environment can support.
Differential survival and reproduction: Individuals with advantageous traits are more likely to survive and reproduce, passing their traits to the next generation.
Natural selection: Over time, natural selection leads to the accumulation of advantageous traits and the elimination of disadvantageous traits.
Speciation: Over many generations, populations may diverge sufficiently to become distinct species.
It's important to note that Darwin's theory of evolution is supported by extensive evidence from many fields of science, including biology, geology, and genetics, among others.
