The line of evidence for evolution that can be gathered from crop scientists breeding different vegetables for various traits from the common wild mustard, brassica oleracea is Artificial selection.

Artificial selection is a line of evidence for evolution where humans intentionally select specific traits to breed in a population, resulting in the development of new breeds or varieties over time. In the case of Brassica oleracea, crop scientists are selecting and breeding the plants for desired traits, which leads to the evolution of different vegetable varieties. This is because humans are intentionally selecting and breeding plants with desired traits, which is similar to how natural selection operates in the wild. Through artificial selection, crop scientists are able to create new varieties of vegetables with specific traits that may not have existed in the wild. This process demonstrates how evolution can occur through selective breeding and adaptation over time.

Answer:

Explanation:

DNA is important in identifying genetic relationships within a group, but it alone is not sufficient to determine complex social constructs like race, whiteness, or property; the inclusion of social, cultural, and historical factors is crucial in understanding these concepts.

Biological anthropologists and genome scientists should consider the relationship between Europeans and Indigenous people in their research to provide a more comprehensive understanding of human genetic diversity and population history.

DNA analysis can provide valuable insights into genetic relationships within a group, such as determining genetic ancestry or identifying related individuals. However, race, whiteness, and property are social constructs that go beyond genetic factors and are shaped by historical, cultural, and socioeconomic factors. These concepts are complex and cannot be solely explained by genetic data. Therefore, it is important for researchers, including biological anthropologists and genome scientists, to recognize the limitations of genetic data and consider the broader social context when studying race, whiteness, and property.

In the context of researching Europeans and Indigenous people, it is crucial for researchers to acknowledge and incorporate the historical and ongoing relationships between these groups. This includes understanding colonization, displacement, and the impact of power dynamics on genetic diversity and health outcomes. By including this relationship in their research, scientists can contribute to a more accurate and nuanced understanding of human genetics and promote social and scientific equity.

Because Solar Radiation

Explanation:

I remember learning this in class. Thermosphere temperature increase because it absorbs solar radiation from the sun.

The osmosis diagram is the one that most accurately represents how a plant cell might change in appearance after spending thirty minutes in a concentrated sugar solution.

Osmosis is the process by which water molecules move from an area with a lower concentration of solutes to an area with a higher concentration of solutes across a semi-permeable membrane.

If a concentrated sugar solution were present, the solute concentration outside the plant cell would be higher than that inside.

Water from inside the plant cell would naturally try to exit the cell as it is submerged in the concentrated sugar solution in an effort to balance the solute concentration on either side of the cell membrane.

Answer:

Heat/temperature

Explanation:

"There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements." These give the core and a few of the outer layers of the earth more and more heat.

Answer:

Traits acquired during an organism's lifetime cannot be passed

Explanation:

The law of use and disuse of organs as postulated by Jean Lamarck was wrong due to the fact that environmentally acquired characters cannot be passed to offspring.

Changes to organisms that are not the level of the gene cannot be passed to the offspring. For example, a wrestler that got big muscles due to constant work out cannot pass big muscles to his offspring. The offspring will need to work out in order to have big muscles. This is because big muscles in the wrestler is environmentally acquired.

Only changes that happen to the genome of an organism (mutation) can be passed to offspring.

In humans, sister chromatids are distinct from one another, although they are identical in animals: Animal spindles lack microfibrils, but the spindles in the spindles contain both microtubules and microfibrils.

A tiny, hollow tube-like structure that can be discovered in the cytoplasm of both plant and animal cells. The form of a cell is supported in part by microtubules. Animal cells have cytoplasmic microtubules that resemble the mitotic spindle fibres and are linked to centriole satellites. The existence of these proteins and their potential contribution to cell shape maintenance are examined. Spindle fibres protrude from the centrioles in animal cells. However, spindle fibres arise from the cell's centrosome area in plant cells, which do not have centrioles.

Phytoplankton are responsible for providing up to 50% of the oxygen that people breathe, as the oceans cover 71% of the world. Thus, option D is correct.

Microalgae, sometimes referred to as phytoplankton, are similar to terrestrial plants in that they have chlorophyll and need sunlight to survive and develop. They provide food for a variety of sea animals in a healthy ecology.

Phytoplankton produce oxygen and nutrition for other species through the process of photosynthesis, which involves the use of sunlight, nutrients, carbon dioxide, and water.

Therefore, Most of the photosynthesis on Earth is done by phytoplankton in the ocean.

Since plants and photosynthetic protists do not have the machinery for being heterotroph but they can make their own food in the presence of chloroplast, this is the reason why they possess chloroplast. Animals cells on the other hand cannot perform photosynthesis and hence do not possess chloroplast.

Heterotroph is one of the types of mode of nutrition. In this the organism obtains their food from some other organism that can either be plant or another animal. The example of heterotrophs are all the animals and humans.

Photosynthesis is the process of synthesizing food by capturing the sunlight energy and releasing oxygen as the by-product.

The correct answer to the question is a) Transduction. The process of transduction plays a crucial role in our ability to perceive and interact with our surroundings.

Transduction is the process of converting one form of energy into another, and in this case, it refers to the conversion of stimulus energy into neural signals by cells in the eye. These neural signals then travel through the optic nerve to the brain, where they are processed and interpreted as visual information. The process of transduction is essential for sensory perception, as it allows for the detection and interpretation of stimuli in the environment. Without transduction, our brains would not receive the necessary information to create a visual representation of the world around us.

Option A, Water loss is accelerated by atrial natriuretic factor. By increasing salt excretion, it induces water loss.

Guanylate cyclase is activated in the collecting duct when atrial natriuretic factor receptors are stimulated, which leads to an increase in cGMP synthesis and, in turn, an increase in salt and water excretion. Vasodilation, enhanced vascular permeability, and increased renal excretion of salt and water are at least three of the acute processes through which atrial natriuretic peptide (ANP) reduces plasma volume. In order to promote salt and water excretion (natriuresis), ANP operates on the kidney in the following ways: ANP primarily controls sodium excretion through the medullary collecting duct.

Most commonly, catabolic mechanisms like glycolysis that degrade energy molecules to create ATP need NAD+.

NAD+, an oxidizing agent that takes electrons from other molecules to become reduced, is present in cells in two different forms.

As a result of this reaction, NADH is produced, which can be employed as a reducing agent to provide electrons.

To supply energizing electrons for the electron transport chain, NADH is needed.

Therefore, ADP and NAD + molecules that form during cellular respiration have less energy than molecules they were produced from.
