When a warm front is approaching, what happens?
A. advancing cold air pushes up and over retreating warm air causing warm temperatures and mild rain
B. advancing cold air pushes up and over retreating warm air causing warm temperatures and mild rain
Answer:
B?
Explanation:
if warm temp is coming then cold air pushes over warm air causing warm temp
When a warm front is approaching then advancing cold air pushes up and over retreating warm air causing warm temperatures and mild rain. Option A is correct.
A warm front is a boundary between warm and cold air masses. When a warm front approaches, the warm air mass is forced to rise over the cold air mass. This causes the warm air to cool and condense, which produces clouds and rain. The rain is usually light and steady, and the temperatures are mild.
The warm air mass is less dense than the cold air mass, so it rises up over the cold air mass. As the warm air rises, it cools and condenses, forming clouds. The clouds produce light, steady rain as the warm air continues to rise. The temperatures are usually mild during a warm front, as the warm air mass is slowly mixing with the cold air mass. Option A is correct.

In cattle, a single gene with two alleles determines fur color. The fur can be red, white, or roan. Roan fur has both red and white hair. Which of the following is true about alleles for fur color in cattle?
The allele for roan fur color is dominant over red and white fur color.
The allele for red fur color is dominant over white and roan fur color.
The roan and white alleles are expressed independently of the other.
The red and white alleles are expressed independently of the other.
Answer:
D
Explanation:
D the red and white alleles are expressed independently of each other. You know this because roan is when both red and white are present. So therefore, because of this, the cow can be red, white, or both depending on what alleles are present.

Kettlewell's experiment is included in most biology texts as an example of evolution occuring. How do we know that the moths evolved?
(peppered moths)
Answer:
The environment the moths lived in used to be unpolluted. This made dark moths rare. As the area where light moths were found became more polluted, the light moths became less common in the polluted/dark areas. Light Moths began to evolve after not being able to survive in dark forests, they began to get darker and blend in with the polluted area to be safe from predators.
Explanation:
The evolution of the moth is an evolutionary instance of directional color change in the moth population as a result of air pollution due to the industrial revolution.
During the nineteenth century in the United Kingdom, the dark (melanic) form of the peppered moth become the dominant form of the peppered moth. Before this change, there are very fewer numbers of dark moths were present and light-colored moths were common.
This change in frequency occurred due to Industrial Revolution as it increased air pollution and trees became darker.Due to this change, light-colored moths were visible to birds and this leads to increase predation of these moths.The darker form of the moth was less visible to predators.The color change was due to adaptive evolution mainly to a single gene, with the melanic allele being dominant to the non-melanic allele. At the end of the twentieth century, the atmosphere become clear once again in the United Kingdom.The new changes would lead to a decrease in the frequency of the melanic form.Thus, the evolution of moths was due to the adaptive selection type of natural selection.

Explanation:
Evaporation of water from oceans at the equator is an example of an interaction between the cryosphere and hydrosphere. So, the correct option is (E).
What are Hydrosphere and Cryosphere?The cryosphere is define as the part of Earth's climate system which includes solid precipitation, snow, sea ice, lake and river ice, icebergs, glaciers and ice caps, ice sheets, ice shelves, and seasonally frozen ground. The word is derived from the Greek word 'kryos' which means frost or icy cold.
The hydrosphere is defined as the sum of the Earth's water such as seas, land, surface, and air. About 71 percent of the Earth's surface is covered by water where only three percent is fresh water. Even less can be used as drinking water. They both interact at equator in the form of Evaporation.

- Describe what happens to a fertilised egg cell before implantation in the uterus.
Answer:
During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.

Question 1 After evaluating your MyPlate recommendations, make a prediction. Do you think your diet will meet these daily recommendations? Are there any recommendations you don't think your diet will meet?
Answer and Explanation:
I don't think MyPlate's recommendations will meet my daily recommendations because those recommendations are focusing too much on the amount of carbohydrates and are not meeting the need for other types of elements, such as healthy fats, for example. In that case, an extremely high carbohydrate diet will get me into trouble and make my body need it. Ideally, I should look for recommendations from a nutritionist who can, in fact, help me establish a healthy and complete diet.

does anyone know the answer??! HERE IS THE Q:
In pea plants, green peas are dominant to yellow peas. What would be the phenotypic percentages of the offspring that would result in a cross between a green heterozygous pea plant and a yellow pea plant? *
50% Gg, 50% gg
100% Gg
50% green, 50% yellow
100% green
Answer and Explanation:
Here is the given information:
Green peas are dominant, so we will put them as capital G.
Yellow peas are recessive (meaning they don't show if there is a dominant allele - trait), so we will pit them as lowercase G.
A Green Heterozygous (different, in this case, has both G and g, or Gg) pea plant.
A Yellow pea plant (will have both lowercase g, or gg).
To find the phenotypic percentages, we make a chart and solve.

What are some freshwater systems and what do they all share in common?
Answer:
There are three main types of freshwater biomes: ponds and lakes, streams and rivers, and wetlands. We'll go into the details of each below. Ponds and lakes are often called lentic ecosystems. This means that they have still or standing waters, not moving like rivers or streams.
Explanation:
Water is broadly classified as fresh and salt water. Examples of fresh water systems I know are;
Ponds, rivers, lakes, and reservoirs.Similarities among all these sources of water are the fact that;
They are all small bodies and have a low amount of salt. They are also shallow and not dense.Fresh water makes up about 1 percent of the world's surface area whereas salt water which is found in large bodies of water takes more than 95% of the earth's surface area.
Smaller bodies of water are mainly freshwater. These are shallow, have low salt content, and are not quite dense. Large bodies like oceans and seas are known to have high salt content.

Answer:c
Explanation:
Take the terms below and use them to write a short paragraph describing how an
ecological community could function.
- sunlight
- precipitation
- temperature
- soil
- plants
- animals
- herbivores
- carnivores
- omnivores
- decomposers
*pls help me*
Answer:
Carnivores will feed on herbivores, omnivores, and other carnivores in an ecosystem. A natural community depends on the presence of carnivores to control the populations of other animals. Large carnivores include wolves and mountain lions. A large carnivore might hunt down large herbivores such as elk and deer. Medium-sized carnivores include hawks and snakes, and these animals typically feed on rodents, birds, eggs, frogs, and insects. Examples of small carnivores include some smaller birds and toads. These carnivores may eat insects and worms. Carnivorous animals have strong jaws and sharp teeth to enable them to tear and rip prey. These animals often have long, sharp claws that they also use to tear prey. Carnivores depend on sufficient prey in the food chain to give them the food they need. If the herbivore population or the population of other carnivores declines in an ecosystem, carnivores may not survive.
explain how the population of octopuses and seaweed in this ecosystem might be affected if a disease reduced the crab population
Answer:
Seaweed might start to grow out of control withough crabs eating it, octopuses on the other hand would struggle to find food and start to die off because they relie on crabs to be their food source.
Without crabs to consume it, seaweed would start to grow out of control; octopuses, on the other hand, might struggle to find food and begin to disappear because they depend on crabs as a food supply.
What is the role of seaweed and octopus in ecosystem?
Seaweeds are important components of marine ecosystems. They serve as the primary source of nutrients and energy for marine organisms.
Either directly when fronds are consumed or indirectly when decomposing sections break down into small particles that are ingested by filter-feeding species.
No other creature has a predatory function as significant as that played by octopuses in forming communities.
Therefore, the population of octopuses and seaweed in this ecosystem might be affected if a disease reduced the crab population.
