Answer:

There can be alternate explanations for the same evidence

Explanation:

The geology and the biology are two different scientific fields, thus the geologists and biologists have different focus and viewpoints when examining something. When a same experiment is done by scientists from two different fields, it is very likely that the conclusions would be different. The main reason for this is that both of them will have different view and methods to come to the conclusion, as their focus is on different things, or at least the approach is different.

Animals in the Alpine biome have adapted to survive temperature fluctuations through migration, like the Arctic Tern, Monarch butterflies, and Reindeer. Others, like the Snow Leopard and Cheetah, have physical adaptations such as thick fur and fast speed. Still others use behavioral adaptations like mimicry and camouflage.

Animals living in the Alpine biome have developed several interesting survival adaptations. Temperature fluctuations are a major challenge they face which many of them have adapted to by adopting a strategy of migration. For example, the Arctic Tern makes a 40,000 km round-trip flight each year between both hemispheres to find food and suitable breeding grounds while Monarch butterflies and Reindeer also migrate significant distances for similar reasons.

Some other kinds of adaptations include physical changes to their body. For instance, the thick fur of Snow Leopards is an adaptation for surviving in cold conditions and a Cheetah's fast speed helps it catch prey effectively. Besides these, there are also behavioral adaptations like mimicry and camouflage which animals employ for survival.

However, not all animals migrate because of the risks and high energy costs associated with migration. Also, some classes of animals like amphibians and reptiles are more limited in their distribution because they generally lack migratory ability.

Answer:

D

Explanation:

A rough steep mountain habitat will have a higher rate of speciation than a large open grassland. The reason for that is that the open grassland has monotonous living conditions all through it, thus the species are the same with the same adaptations all over it. The rough steep mountain habitat, on the other hand, has multiple different living conditions. The different living conditions are defined by the elevation, and in accordance to it there will different species living at different elevations. Also, the mountain is a natural barrier for the air masses, so while on one side of it there's rainfall, on the other one there's dry weather conditions, which again creates different living conditions, different adaptations by the living organisms, thus different species.

Convection currents transfer heat from warmer regions to cooler regions

Convection currents transfer heat from one place to another.

Convection currents transfer thermal energy from warmer to cooler region.

Option C

Explanation:

Thermal energy is transferred by convection from hot places to cold places. It is form of "kinetic energy" that is transferred as heat. When the hot liquid or gas becomes cool liquid or gas then convection happens. Then the cooler gas or liquid will goes to the place of hotter gas or liquid. This results in a "continuous circulation sequence".

"Water boiling" in a beaker is one of good examples of these "convection currents". Atmosphere is also example of convection. The Earth surface gets heat by sun the warm or hot air rises and cool air moves in. Other options are incorrect as thermal energy transfers from warm to cool places by convection.

Answer: Phloem

Explanation: In  higher plants, the phloem is a vascular tissue that carries sugars and other nutrients synthesized from the organs that produce them, to those in which they are consumed and stored. The phloem is organized in vascular bundles (see image below) , which are  longitudinal filaments of the conductive tissue associated with the water-conducting tissue or xylem. The vascular bundles are important structural organs of the herbaceous stems and the leaf nerves.

Answer:

The site of photosynthesis of a plant a.k.a kitchen of a plant is the leaf.

Explanation:

The leaf is the site of photosynthesis because its broad surface can absorb sunlight. Chloroplast is present in leaves, which contains chlorophyll which is a key factor of photosynthesis. The leaf has stomata under its surface which is responsible for gaseous exchange. Therefore, leaves act as the primary location for photosynthesis.

Hope this helps <3

Final answer:

Leaves are the major site of photosynthesis in plants, specifically within a layer called the mesophyll, and gas exchange occurs through regulated openings known as stomata.

Explanation:

The major site of photosynthesis in plants is the leaves. Photosynthesis occurs in a middle layer of the leaf called the mesophyll, where cells contain chlorophyll, the green pigment crucial for this process. The gas exchange of carbon dioxide and oxygen essential for photosynthesis takes place through the stomata, which are regulated openings typically found on the underside of the leaf. These stomata are controlled by guard cells that respond to osmotic changes to regulate the loss of water and the intake of carbon dioxide.

Photosynthesis is the process in which green plants, algae and some bacteria convert light energy from the sun into chemical energy in the form of glucose (a type of sugar) and oxygen. This process takes place in the chloroplasts which are located in the leaves of a plant. The chloroplasts contain chlorophyll, a green pigment that captures light energy from the sun and uses it to convert carbon dioxide and water into glucose and oxygen during photosynthesis. Therefore, the correct option is D. Leaves.

Answer:

- Species A and C may have shared features from a common ancestor

- Species B and E may have shared features from a common ancestor

- Species A is more related to species B than species B is related to (any of the other species)

Explanation:

From this phylogenetic tree we can see that all five species have a shared distant, common ancestor, meaning that they all evolved from a single species. Because they all share the same common ancestor, there's every chance that the species A and C, or species B and E, share some features from their common ancestor even though they have become separate species and have been so for longer period of time. If we look at the present bonds, than we can see that the species A and B are much more closely related between each other than with any of the other species, and the same can be inferred for the species D and E.

Based on the phylogenetic tree, we can surmise that Species A and C, Species C and D, as well as Species B and E share features from common ancestors, with the shared features indicating the degree of relatedness and the likelihood of more recent common ancestry for each paired comparison.

Analyzing a phylogenetic tree helps us understand the evolutionary relationships between different species. When a scientist conducts a genetic analysis by determining the number of genetic similarities among species, certain patterns emerge. These patterns allow us to make educated statements about the relatedness of different species.

Based on the information given, we can deduce the following:

The interconnectedness reflected on the phylogenetic tree serves as a visual representation of these genetic relationships, where closer branches indicate more recent common ancestry and therefore greater genetic similarities.

Option D, decreased variation in the shades of red because the only reason for variation was selection pressure

Explanation:

Certain factors which make an organism with in its species selective over other which provide an added leap of survival over others.  

Here, red color of male cardinal has only purpose and this purpose is to attract females thereby making themselves a selective species over other male species.  

Now, if somehow females start selecting males on the basis of some other characteristics then it is sure that the variations in the color of male cardinals will gradually slow down and eventually will stop as selective pressure was the only cause of their variation.

Answer:

The short answer is that an allele is a variant form of a gene.

Explanation:

Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known as alleles. A given gene may have multiple different alleles, though only two alleles are present at the gene’s locus in any individual.

PLEASE GIVE ME BRAINIEST

An allele is one of multiple forms of a gene that exists at the same location on a chromosome and is responsible for the variety observed in the traits of organisms. Alleles can give rise to different phenotypes, which depend on their combination in the genotype of an individual. The expression of alleles can follow different patterns like incomplete dominance or codominance.

An allele is one of two or more alternative forms of a gene that arises by mutation and are found at the same place on a chromosome. Alleles can lead to different phenotypes, or observable traits, in an organism. For instance, a gene that determines flower color in a plant might have two alleles, one resulting in red flowers and the other resulting in white flowers. The combination of alleles that an organism has, known as its genotype, directly impacts its phenotype. Different patterns, such as incomplete dominance or codominance, can influence the outcome of an organism's phenotype when two different alleles are present.

In cases of incomplete dominance, the phenotype of the heterozygous genotype (where two different alleles are present, such as Aa) is often intermediate between the phenotypes of the homozygous genotypes (where two of the same alleles are present, such as AA or aa). Codominance is a condition where both alleles of a gene pair in a heterozygote are fully expressed. For instance, the AB blood type in humans is a result of codominance, where both A and B alleles are expressed.

Upwelling improves the nutrient supply at coastal fisheries as the cold, nutrient-rich water replaces the warm, nutrient-poor surface water

Explanation:

The upwelling is simply the process through which the cold water rises up toward the surface, pushes and moves away the warmer water, until it gets warmer and is pushed by the colder water blow it. The cold water that rises toward the surface is nutrient-rich, while the warm surface water is nutrient-poor. By having the nutrient-rich cold water come toward the surface, the coastal fisheries have great benefit, as the more nutrients there are, the more fish there will be for them to catch.
