Explanation:

Answer:

Andy’s car rolls down a hill with the engine off.

A balloon expands as it is heated by the Sun.

Explanation:

Work is said to be done when a force applied on an object is able to move/displaces the object from its position. But, if force is applied on an object but it does not move or force which is being applied on the object is prependicular to the object in such situations work done is zero.

The formula for work done is mentioned as under:

        W = F.d. cosФ

Where, W = Work done

            F  = Force applied

            d  = displacement

            Ф = angle between force and displacement

So if Ф = 90° then cosФ = 0 and hence, W = F.d. cosФ = F x d x 0 = zero &

W = F.d. cosФ = F x 0 x cosФ = zero, when d = 0.

Andy’s car rolls down a hill with the engine off -  In this situations work is said to be done because there is a net movement of the object in the direction of force.

A balloon expands as it is heated by the Sun - In this situation work is said to be done due to heat expansion.

Hannah leans against her locker, but it doesn’t move, a wind turbine stands still on a sunny, windless day & James pedals a stationary exercise cycle that doesn’t move - In all these situations, work done is zero because there is no net displacement. i.e. d = 0.

Answer:

A. A gene is removed

Explanation:

Answer: Third option is correct.

Explanation:

Genetic engineering is a method of artificial manipulation, modifications and recombination of genes to modify the population of any organisms.

In this type pf engineering, genes get inserted to make a mutation inactive or a gene is removed.

But no synthetic gene is created by this process.

Hence, third option is correct.

Answer:

The amount of ⛅ sunlight .

Explanation:

PLEASE MARK AS BRAINLIEST

The grass turned from green to a yellowish white color due to decreased sunlight and possibly increased moisture under the bucket.

The change in color of the grass from green to a yellowish white under the bucket is most likely due to the decreased amount of sunlight reaching the grass.

chlorophyll, the green pigment in plants, is responsible for capturing sunlight for photosynthesis.

Without adequate sunlight, chlorophyll production decreases, causing the grass to lose its green color.

Increased moisture under the bucket may also contribute to the change in color, as excessive water can lead to stress and damage to the grass.

Answer:

Oxygen...

Explanation:

Organisms decompose more quickly when they are in contact with oxygen. ... When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts.

Final answer:

Organisms do not always become fossils due to the specific and uncommon conditions required for fossilization, such as rapid burial in sediments or extraordinary preservation environments. The fossil record is thus incomplete, capturing only a fraction of past life forms under certain conditions.

Explanation:

Not all organisms become fossils when they die because the conditions required for fossilization are quite specific and rarely occur. Remains must be rapidly covered by sediments or preserved in unique circumstances such as being frozen in glaciers or trapped in tree resin. The environment plays a crucial role in preserving fossils, with physical conditions like temperature and water depth, and chemical conditions such as pH and oxygen levels greatly influencing this process. Organisms that do not get preserved in such a way eventually decompose fully.

Fossils help paleontologists understand Earth's history, evolution, and paleoenvironments. They also indicate that most species that have lived on our planet are now extinct. Fossils are not only a window into the past, but they are also a finite non-renewable resource, as is the case with fossil fuels derived from ancient organisms that decomposed under specific anaerobic conditions over millions of years.

While most remains eventually deteriorate, under favorable conditions such as volcanic ash, limestone, and mineralized groundwater, fossilization can occur, although it remains a rare event. This results in an incomplete fossil record, as the conditions for preservation don't happen frequently enough to capture all past life forms.

The transfer of energy through force application causing a body to move in the direction of the force is defined as 'work' in physics. This concept is closely related to 'power', which is the rate of energy transfer in a system. It is an integral part of studies in mechanics and thermodynamics.

The transfer of energy to a body by applying a force that causes the body to move in the direction of the force is called work. This energy transfer occurs when an external force is applied to an object system, causing it to move through a distance. In terms of physics, work is the product of the force's component in the direction of the displacement and the magnitude of the displacement.

As an example, consider a piston filled with gas being compressed or expanded. The work done on the piston is equated to the energy transferred into the piston system. This concept is part of thermodynamics, a fundamental aspect of physics that studies the movements and interactions of energy.

Power is closely related to work, defined as the rate of energy transfer into, out of, or within a system. So, if we look at the power involved in moving a body, it can be expressed in terms of the forces acting on it. The higher the rate of work done, the greater the power exerted over the system.

Answer:

They make up the gene and decode what it is and does.

Explanation:

Alleles from the same gene are related because while they both come from different people, they affect the same gene. The two or more alleles make up the gene they form. They also decide whether the gene will be dominate or recessive.

Alleles are different versions of a gene that determine traits, with each parent contributing one allele to the offspring. There can be dominant and recessive alleles that influence the phenotype, and individuals can be homozygous or heterozygous for a trait.

Alleles for the same gene are related because they are different versions of the same gene that determine various traits such as eye color, blood type, or hair color. Each allele contains a unique sequence of DNA, which can result in different physical characteristics, known as the phenotype. We receive one allele from each parent, giving us two alleles for each gene, which can be either homozygous (identical alleles) or heterozygous (two different alleles). Genes can express themselves in various ways; some alleles are dominant while others are recessive, and this interaction is essential in determining an organism's traits. For instance, the gene for blood type has three possible alleles: A, B, and O. Homozygous individuals have two identical alleles while heterozygous individuals have two different alleles, which can result in varying expressions of the gene.

Answer:

Behavioral isolation.

Explanation:

SInce the example is saying that both species of frogs are in the same area, this eliminates the option of geographical and habitat isolation, since they are already togheter and have similar diet, appearence and DNA this means they could interbreed, and since the example is not saying anything about breeding times for each species, we can not assume this is a temporal isolation, so the only thing that sets them apart is the fact that they have different breeding rituals, since one species breeds on water ponds and the other in fast-moving streams, this is known as Behavioral Isolation, since it´s their breeding rituals that keeps them from interbreeding.

segmented worms

Explanation:

Segmented worms are the most complex animals with worm-like body plans.

Final answer:

The segmented worm is the type with a body divided into ring-like parts, and they belong to the phylum Annelida, with earthworms as common examples.

Explanation:

The type of worm that has a body divided into many ring-like parts is the segmented worm. Segmented worms are part of the phylum Annelida, which includes earthworms, leeches, and some marine worms. These worms have bodies that are segmented, meaning their bodies are separated into repeating units. Earthworms are common examples of segmented worms, and they play a critical role in enriching and aerating the soil, supporting terrestrial ecosystems. Additionally, segmented worms typically have well-developed organ systems, with a complete digestive tract, a fluid-filled cavity that acts as a hydroskeleton, and a more developed nervous system compared to other worm types like roundworms and

(C)theories can be used to predict the existence of as of yet unobserved things or phenomena

Final answer:

The true statement about scientific theories is that they can be used to predict unobserved phenomena. Theories are well-established frameworks, different from hypotheses, that can be empirically tested and are not ethical precepts. The correct option is: (C) theories can be used to predict the existence of as yet unobserved things or phenomena.

Explanation:

This statement is true because scientific theories are not merely guesses; they are comprehensive frameworks supported by a body of evidence that can make predictions about the natural world.

Theories can be tested and they are different from hypotheses. Theories are much more established and are supported by evidence collected from multiple experiments or observations. Also, they are not based on ethical or religious principles, but rather on empirical evidence. A theory may begin as a hypothesis, which is a proposed explanation made on the basis of limited evidence as a starting point for investigation. However, once a hypothesis has been tested repeatedly and consistently supports the evidence, it may become a theory.

In science, theories are crucial because they provide explanations that predict and can be tested in various ways, and can be used to understand and predict the occurrence of future events or discoveries. When new evidence appears that contradicts a theory, the theory is reconsidered and may be revised. This is how science advances knowledge.

Scientists know that organisms that are more closely related will have DNA sequences that are more similar to each other than organisms that are distantly related, the two organisms that would most likely have the fewest similar nucleotide sequences are humans and the bacterium present in Option a.

The relationship between evolutionary relatedness and DNA similarity arises from the fact that DNA sequences change over time while mutations can arise through various mechanisms, such as errors in DNA replication or exposure to mutagens, etc. As a result, organisms that diverged more recently from a common ancestor are expected to have more similar DNA sequences and more evolutionary relatedness than those that diverged further back in time.

Hence, the two organisms that would most likely have the fewest similar nucleotide sequences are humans and the bacterium present in option a.

a)humans and the bacterium

b)human male and the human female

Answer:

Codominance

Explanation:

When we say codominance, both traits of the parents are seen on the offspring. For example in your problem, the offspring is speckled meaning there is a mixture of both white and black, traits coming from each parent.

Do not confuse this with incomplete dominance. Incomplete dominance is similar but the difference is that the traits are "BLENDED". So let's say that if incomplete dominance occurred, the offspring would be gray.

The described inheritance pattern, in which a cross between a black and white chicken produces all speckled offspring, is known as codominance. This pattern of inheritance happens when neither of the two alleles of a gene is dominant or recessive, resulting in offspring that display traits from both parents.

The type of inheritance described in the question, where a cross between a black chicken (BB) and a white chicken (WW) produces all speckled offspring (BW), is known as codominance. In codominance, both alleles are equally strong and both are expressed in the offspring's phenotype. In this case, neither the black color (B) nor the white color (W) is dominant over the other, resulting in a speckled combination of both colors (BW).

Bringing in a different context, in cases of codominance in mice, a cross between a black mice (A) and a white mice (a) will produce grey mice (Aa). Many genetic traits indeed follow this pattern of inheritance.
