why are summer days longer than winter days on earth ?
Answer:
3. The region of Earth => away from the sun.
Explanation:
In the summer months, the northern half of the Earth, where we live, tilts towards the Sun. The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. This means we get more sunlight, making the days longer.

Why do animals become adapted to their environments?
Answer:
An adaptation is a way an animal's body helps it survive, or live, in its environment. Camels have learned to adapt (or change) so that they can survive. Animals depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates.
Explanation:
:)
Answer:
All organisms need to adapt to their habitat to be able to survive. This means adapting to be able to survive the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space. ... An animal may adapt to its habitat in different ways.

Corn kernels can be high in starch (starchy) or high in sugar (sweet). The allele for starchy kernels (H) is dominant to the allele for sweet kernels (h). Each kernel on an ear of corn represents an individual offspring. A particular ear of corn has 92 starchy kernels and 88 sweet kernels. What are the MOST likely genotypes of the parent corn plants that produced this particular ear of corn?
Answer:
Hh, Hh
Explanation:
The allele is the two or more variants of a specific trait present on the genes of the organism that is responsible for giving a particular physical and genetic attribute. The allele can be dominant or recessive.
The most likely genotype of the parent is Hh and hh.
How to know the genotype of the parent plant?The genotype of the parent plant can be estimated by crossing the heterozygous F1 generation with the recessive purebred parent plant. This type of cross is called a test cross.In the question, the offspring with the starchy and the sweet kernels is approximately in a 1:1 ratio. The offspring can be heterozygous dominant for the starchy kernel and purebred recessive for the sweet kernel.The heterozygous dominant offspring is crossed with the recessive purebred parent plant and will give the genotype.Thus, the genotypes are Hh and hh.

Describe the environmental conditions that extremophiles are able to live in. Describe the environmental conditions that extremophiles are able to live in. Extremophiles were microbes that could only live in conditions that prevailed early in Earth's history when environments had high temperatures and pressure and lacked oxygen. Extremophiles includes those microbes that thrive in very high-salt, high-temperatures, low-temperature, high-pressure, low-pH, or high-pH harsh conditions. Extremophiles can only survive in habitats where there are extreme changes in close proximity, such as hydrothermal vents at the bottom of the ocean, where water as hot as 300°C emerges and mixes with 4°C seawater. Extremophiles are able to tolerate extreme conditions found in space such as a near vacuum and temperatures in excess of 300°C or several hundred degrees below 0°C.
Answer:
Extremophiles includes those microbes that thrive in very high-salt, high-temperatures, low-temperature, high-pressure, low-pH, or high-pH harsh conditions.
Explanation:
Extremophilic organisms are life forms that can grow in extreme environmental conditions, such as the above mentioned. In general, extremophiles are prokaryotic organisms (i.e., archaea and bacteria), although there are some eukaryotic species that are considered extremophilic organisms. Extremophiles are classified into two main types: 1-microorganisms that live in extreme conditions and 2-microorganisms that have the ability to tolerate extreme environmental conditions. Extremophiles are extremely important both in basic and applied research. An example of this is the thermostable Taq DNA polymerase obtained from the bacterium Thermus aquaticus (an extremophile that lives in areas of high temperature and pressure), which is essential to carry out the Polymerase Chain Reaction (PCR).

Most of the ocean floor is a type of rock called basalt. At the edge of continents, this basalt erodes and becomes small particles. Over time, the particles are compressed and form what type of rock? A. Igneous B. Basinic C. Metamorphic D. Sedimentary
Answer: D. Sedimentary
Explanation:
Sedimentary rocks are formed overtime are different particles of sand, shells, pebbles and other fragments of materials form layers and harden into rock.
The particles are compressed and form sedimentary rocks in the ocean floor. Ocean floor is the bottom of the waterbody. Thus, the correct option is D.
What is Ocean Floor?The seabed or ocean floor is the bottom of the ocean. All the floors of the ocean are known as 'seabed'. The structure of the ocean floor of the global ocean is governed by the plate tectonics.
Most of the parts of the ocean are deep, whereas the ocean floor is known as the abyssal plain. The seabed also known as the seafloor, ocean floor, and ocean bottom is the bottom of the ocean.
The ocean floor can be divided into three distinct regions which are the continental margins, abyssal plains, and the mid-ocean ridges. The ocean floor has rocks which are called basalt. Here, the basalt particles are compressed which forms the sedimentary rocks. Sedimentary rocks are formed by accumulation of minerals.
Therefore, the correct option is D.

A food development company is interested in making on-the-go powder-based snacks in which consumers can "just add water" before eating. During market tests there are complaints that the powder does not dissolve well in water.If you were a food scientist, how might you modify the formula so that it will more easily dissolve in water? Provide your answer in 1-2 complete sentences.
The correct answer to this open question is the following.
Although there are no options attached we can comment on the following.
I might modify the formula so that it will more easily dissolve in water in the following way. I would ask my scientist in the laboratory to modify the formula. To make the formula more soluble when it makes contact with water, the addition of polar hydrophilic side groups to the molecule will help the formula to be soluble.
That is why it is very important to do focus groups to taste the product before launching it commercially and send the product to the stands of supermarkets, pharmacies, or grocery stores. If it is not previously tasted, you could encounter many difficulties. Furthermore, the FDA requires the best quality of the product so you have to make sure it works as it says in your advertisement.

What letter is the second layer of the rock?
Answer:
Soil is a basic and fundamental natural resource, which took millions of years in its formation, resulting from the processes of disintegration and decomposition of rocks due to weathering. As much as many rocks, due to their hardness levels, seem indestructible, they all end up decomposing, even if slowly. Weathering is the general process that causes the deterioration of rocks. He is responsible for producing all the clays, all soils and dissolved substances that end up carried by rivers to the oceans. We can subdivide it into two types: chemical weathering and physical weathering. The first occurs when the minerals of a given rock undergo a chemical alteration or dissolution – and here the action of water is very important. The second occurs when there is a fragmentation of solid rock, through mechanical processes that do not change its chemical composition. Both reinforce each other. The smaller the pieces of rock created by physical weathering, the greater the surface for chemical weathering to act.
Rocks, reduced in particles through weathering, can accumulate as soil or, through erosion, be transported or deposited in the form of sediments somewhere else. Erosion is then defined as the process in which weathered materials (i.e., dismantled into smaller mineral fractions) are displaced or removed from their origin, usually by the action of water or air currents. A third geological process that should be mentioned is the dispersion of mass, which usually moves in isolated events, downhill, terrestrial materials modified or not by weathering, including large fragments of unchanged rocks.

Directional selection differs from stabilizing selection in that:
a.Directional selection favors one extreme phenotype, whereas stabilizing selection favors intermediate over extreme phenotypes
b.Directional selection requires new mutations whereas stabilizing selection uses existing variation
c. Directional selection operates only in small populations, whereas stabilizing selection only works in large populations
d. they both do nothing, these are terms I made up while writing this retake
Answer:
a. Directional selection favors one end of the phenotype distribution, whereas
stabilizing selection favors intermediate over extreme phenotypes
Explanation:
Directional selection is called directional because it favors one phenotype over another, and stabilizing selection finds a balance between phenotypes.
Directional selection differs from stabilized selection in that it prioritizes one end of the phenotypic distribution, but stabilized selection prioritizes the middle over extreme phenotypes.
What is phenotype selection stabilization?The stabilized choice is the opposite of a destructive choice. Prefer intermediate varieties rather than individuals with extreme phenotypes. Stabilization of choice tends to remove more serious phenotypes and results in reproductive success of standard or average phenotypes.
What is an example of a stabilization choice?Stabilization of selection If the evolutionary pressure selects for two extremes of the trait, the population experiences stabilization of selection. For example, plant height can be affected by stabilizing choices. Plants that are too small may not be able to compete with other plants for sunlight.
