Leopards have spots to blend in with the patches of sunlight on the jungle floor.
How might a trait like spots become more common in a population of leopards?

A. Leopards get their spots by rubbing against each other. Eventually all leopards
in a population will have spots.

B. Blending in helps leopards successfully hunt for food. Leopards with more food
are more likely to survive and pass on their spotted trait to offspring.

C. An adult leopard develops more spots during its lifetime in order to compete
with other leopards.

Answers

Option B is the most likely to result in the increased prevalence of spots in a population of leopards. This is because natural selection favors traits that provide a survival advantage. In the case of leopards, having spots helps them blend in with their environment and become better hunters, which increases their chances of survival and reproduction. Over time, this can lead to the spotted trait becoming more common in the population, as individuals with the trait are more successful at passing it on to their offspring.

B is the correct answer. Adaptations that allow animals to survive in an environment are more favored and they will live to pass those traits onto their offspring

what may happen to a solid when it is continuously exposed to heat?

Answers

When a solid is continuously exposed to heat, it may undergo a phase change and transform into a liquid or a gas.

This happens because heat causes the molecules in the solid to gain energy and vibrate more rapidly. As a result, the attractive forces between the molecules weaken, and the solid's structure begins to break down.

If the temperature continues to increase, the solid will eventually reach its melting point and transform into a liquid. This is known as melting or fusion. If the temperature continues to increase even further, the liquid may reach its boiling point and transform into a gas. This is known as vaporization.

However, not all solids will transform into a liquid or gas when exposed to heat. Some solids may undergo a chemical reaction instead, breaking down into new compounds or elements.

From which direction would weather come to a city at 65-degrees north?

Answers

Weather in the northern hemisphere comes in the west to east direction.

The weather is affected mainly by the type of wind and the energy radiated by the earth in that region.  

The rotation of the earth and Coriolis force affect the direction of a wind, making it flow in the counterclockwise direction.

Thus, the wind flows from the subtropic belt to the sub-polar belt, in the west to east direction. Such winds are known as the westerlies.    

Energy that is absorbed by the earth's surface is radiated back into the atmosphere. Due to the rotation and revolution of the earth, there is a variation in the energy absorbed and given back. This also contributes to the weather of an area.

Answers

Answer:

1) Weathering, Erosion, Disposition

2) Physical weathering is the breakdown of large rocks into fragments by physical forces; the chemical composition of the rock is not changed. Chemical weathering is the breakdown of rock by chemical reactions; the chemical composition is changed.

3) The four forces of erosion are water, wind, gravity, and glaciers.

4) Because the velocity of the river slows down a great deal when it reaches the large body of water, the sediment that the river was carrying is deposited along the mouth of the large body of water.

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

Abrasion: Abrasion is the breaking down and wearing away of rock material by the mechanical action of another rock. Three agents of physical weathering that cause abrasion are moving water, wind, and gravity. Also, rocks suspended in thence of a glacier can cause abrasion of other rocks on Earth's surface. This would be a prime example of physical weathering, or mechanical weathering.

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

Acid Precipitation: Acid rain causes less erosion than normal rainwater does. Rainwater can break down rocks by dissolving minerals in the rocks. Acid rain is rainwater that is more acidic than normal rainwater. Acid rain can also dissolve the minerals in rocks faster than normal rainwater can. This is chemical weathering.

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

Animal actions: Animal and plant mobility is a factor in biological weathering. For instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand. A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock. This is an example of physical weathering.

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

Ice wedging: Ice wedging ,sometimes known as frost wedging ,can also cause rocks to break apart. Ice wedging causes cracks in rocks to expand as water seeps in and the water freezes and expands opening the crack further. Rocks formed under pressure deep within earth can become exposed at the surface. This is physical weathering

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

Oxidation: Oxidation is another kind of chemical weathering. It occurs when oxygen from air dissolves in water and combines with chemicals in the rocks to form oxides. if the rock contains a lot of iron, then oxidation produces a brown material called iron oxide. This looks like rust on the rock.

What is the difference between weathering erosion and deposition?

Weathering is the chemical and mechanical breakdown of exposed rock. The chemical changes alter the minerals and make them softer, and mechanical weathering physically breaks rock into smaller and smaller pieces.

Erosion is the REMOVAL of those chemically and mechanically softer and broken pieces of rock from their original locations, by gravity, water, ice or wind. Erosion is transport (and as a result, fresh unaltered rock is exposed to wind, water and weather, and THAT becomes weathered in turn). The material being transported is ‘sediment’: sand, silt, mud and gravel.

Deposition is when the weathered and eroded (transported) material is dropped and settles down elsewhere, forming a ‘deposit’ of transported rock material.

If this deposit remains undisturbed long enough, and is buried by enough arriving material, it will eventually go through compaction and chemical reactions forming cement between the grains - thus resulting in a brand new, sedimentary rock.

Weathering, erosion, transport, deposition, compaction and cementation are part of the ‘rock cycle’.

How can the complete rock cycle be described?

Let’s start with basalt that form at mid ocean spreading centers. At mid ocean spreading centers rock material from the earth’s mantle continuously melts due to continuous decreasing in pressure from the oceanic crust spreading at this point. The molten rock quickly cools at the earth’s surface and forms rock known as basalt that makes up the oceanic crust all over the world. The newly produced oceanic crust rock slowly moves towards a boundary with a continental crust where the oceanic crust subducts beneath the continental crust due to the oceanic crust having a higher density than the continental crust. This is where things get a bit more interesting.

where is mitochondria found abundantly between sperms and ova.Explain​

Answers

Mitochondria are found abundantly in the midpiece of the sperm. The midpiece is located just behind the head of the sperm and contains many mitochondria that provide energy for the sperm to swim towards the egg. The egg, on the other hand, contains mitochondria throughout its cytoplasm. This is because the egg needs a large amount of energy to support the early stages of embryonic development, before the zygote can begin to produce its own energy.

During fertilization, the sperm and egg combine to form a zygote. The mitochondria from the sperm are typically destroyed after fertilization, so the zygote relies solely on the mitochondria from the egg for energy production. This is why mitochondrial DNA is inherited solely from the mother in most animals, including humans.

Your friend left a cage open and several genetically modified frog escaped. Near graduation you find that the population has been living in Tracer pond. Wild frogs are homozygous dominant for smooth skin the genetically modified are homozygous recessive for bumpy skin. There are 826 that are smooth skinned out of the 375 that are heterozygous and 85 frogs have bumpy skin
What is the frequency of the recessive allele?
What is the frequency of the dominant allele?

Answers

To solve this problem, we can use the Hardy-Weinberg equation, which describes the relationship between the frequencies of alleles and genotypes in a population. The equation is:

p^2 + 2pq + q^2 = 1

where p is the frequency of the dominant allele (in this case, the allele for smooth skin), q is the frequency of the recessive allele (in this case, the allele for bumpy skin), p^2 is the frequency of homozygous dominant individuals, 2pq is the frequency of heterozygous individuals, and q^2 is the frequency of homozygous recessive individuals.

We can start by calculating the frequency of the recessive allele:

q^2 = 85 / total number of frogs
q^2 = 85 / (826 + 375 + 85)
q^2 = 0.073

To find the frequency of the dominant allele, we can use the fact that p + q = 1:

p + q = 1
p = 1 - q
p = 1 - 0.073
p = 0.927

So the frequency of the recessive allele is 0.073, and the frequency of the dominant allele is 0.927.

The small intestine is the longest organ of the digestive tube and contains several folds.

Its first portion, the duodene, receives secretions from intestinal glands, such as bile and pancreatic juices, and mixes them with the digestive juices of its production. All these secretions carry large amounts of enzymes that will degrade food and transform it into soluble substances, such as amino acids.

The reason for being so long is that this is the portion of the tube where nutrient absorption occurs. The intestine walls are covered by villi that increase the absorption area. It also transports water from the blood to the intestinal tract, which helps in food decomposition.

The mode of determination for cells in a developing vertebrate spinal cord is mediated by cell-to-cell signaling through Notch signaling pathway.

What is the Notch signaling pathway?

The Notch signaling pathway is a highly conserved signaling pathway that plays a crucial role in regulating cell fate decisions during embryonic development.

In the vertebrate spinal cord, Notch signaling plays a critical role in specifying the fates of neural progenitor cells (NPCs) by promoting the maintenance of NPCs and inhibiting their differentiation into neurons.

This process is mediated by the interaction between the transmembrane receptor Notch on NPCs and its ligand Delta on neighboring cells, which leads to the activation of Notch signaling pathway in the NPCs.

The downstream effectors of the Notch signaling pathway then regulate the expression of genes that control NPC maintenance and differentiation, thereby determining the fate of the NPCs.

Therefore, the mode of determination for cells in a developing vertebrate spinal cord is mediated by the Notch signaling pathway, which is a form of cell-to-cell signaling.
