Answer:

The cells in both plants and animals perform respiration. Carbon dioxide is also released into the atmosphere when fuels are burned, such as in automobiles or factories. Plants take in carbon dioxide and release oxygen through their leaves. Plants use a process called photosynthesis to make their own food.

Explanation:

Cellular respiration is similar in both plants and animals in that it converts glucose and oxygen into energy in the form of ATP, produces carbon dioxide and water as byproducts, and occurs in the mitochondria.

Cellular respiration is a metabolic process that occurs in both plants and animals to convert the energy stored in food molecules into a form that cells can use, called adenosine triphosphate (ATP). In both plants and animals, cellular respiration occurs in the mitochondria and involves a series of chemical reactions, including glycolysis, the citric acid cycle, and the electron transport chain.

During these reactions, glucose and oxygen are consumed, and carbon dioxide and water are produced as waste products. The energy released in these reactions is used to generate ATP, which provides energy for the cell's activities. Additionally, both plants and animals use a similar process, called photosynthesis, to convert light energy into chemical energy.

Answer:

yooooooooooooooooooooooooo

Explanation:

Energy transfer does not always result in a phase change because phase changes involve specific changes in the arrangement and motion of molecules, which are not solely dependent on energy transfer.

Phase changes occur when the average kinetic energy of the molecules in a substance reaches a certain threshold. This threshold is determined by the intermolecular forces holding the substance together. For example, in the case of water, when sufficient energy is transferred to the liquid water molecules, they can overcome the intermolecular forces and transition into a gaseous state (vaporization/evaporation).

Energy transfer alone does not guarantee a phase change because other factors, such as pressure and temperature, also play crucial roles. If the pressure and temperature conditions are not within the appropriate range, the energy transfer may not be sufficient to overcome the intermolecular forces and trigger a phase change.

Different substances have different intermolecular forces and phase change requirements. Some substances, like metals, do not undergo phase changes at typical temperatures and pressures but instead exhibit changes in their physical properties, such as conductivity or magnetism, in response to energy transfer.

While energy transfer is an essential factor in causing phase changes, other factors such as intermolecular forces, pressure, and temperature must be considered for a phase change to occur.

Answer:

It allows the scientists to activate gene expression instead of cutting the DNA.

Explanation:

The development of CRISPR-Cas9 is significant for the scientific community because this development allows the scientists to activate gene expression instead of cutting the DNA. This technique allows the scientists and researchers to study the function of the gene. Before development, Cas9 enzymes produced by the CRISPR system binds to the DNA and cuts it by shutting the targeted gene off so this development of CRISPR-Cas9 enables the scientists to activate gene expression instead of cutting the DNA.

Explanation:

Answer:

1: two 2: wobble 3: eclipsing

Explanation:

A binary star system is made of two stars, one of which is brighter than the other. Astronomers are able to detect the dimmer star because its gravity causes the bright star to wobble. Astronomers can also spot the dimmer star by observing a phenomenon called a(n) eclipsing binary. This happens when the dim star passes in front of the bright star.

The correct answer is -

11. b. somatic cell and sex cell of the same organism.

12. d. all the genetic characters will change.

Explanation:

11. the given diagram represents two types of cells of an organism cell I is the somatic cell as it has two sets of chromosomes or diploid chromosome number whereas cell II is a sex cell such as gametes (egg or sperm) has one set of chromosomes or a haploid number of chromosomes.

12. if there is a change in a nucleotide sequence of DNA of a certain gene takes place then there will be minor or major changes occur in the result of the protein as DNA makes codes of mRNA that code for the specific protein that result in specific gene expression or character. There would be only one character that will change as the change occur only a certain gene.

Answer:

llbb

Explanation:

The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be llbb.

Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.

If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.

No, because lactose is broken down into glucose which is already abundant.

Glucose requires fewer steps and energy to break down than lactose. However, if lactose is the only available sugar, E. coli quickly goes ahead and uses it as an energy source. The lac operon gene that encodes the enzyme must be expressed.

When both glucose and lactose are present lactose binds to the repressor and prevents binding to the operator region. Therefore, lac gene transcription is unblocked and a small amount of mRNA is produced. Because these genes are not transcribed, the levels of these enzymes in cells are very low. In contrast, the presence of lactose greatly increases the synthesis of these enzymes.

The action that BEST demonstrates the transformation of mechanical energy to heat energy is burning a candle (Option B).

Mechanical energy refers to the energy contained by an object due to its motion and/or position. Heat energy refers to the energy caused by the movement of atoms and/or molecules.

Energy transformation refers to the process by which the energy of an object changes from one type to another.

Mechanical energy can be converted into heat energy and vice-versa.

For example, thermal (heat) energy can be used to generate mechanical energy that produces the movement of a turbine generator, which subsequently converts mechanical energy into electrical energy.

As in an adult heart, the prenatal heart develops four chambers and four valves. But because the fetal lungs will not be used until after birth, blood must bypass the lungs. Two structures develop in the prenatal heart that allow the blood to be routed around the lungs: the foramen ovale and the ductus arteriosus.

The foramen that conveys a branch of the trigeminal nerve (CN V) is Foramen rotundum. The correct option is B.

The trigeminal nerve, also known as cranial nerve V, is a mixed nerve responsible for sensory and motor functions of the face. It has three main branches: the ophthalmic nerve (V₁), the maxillary nerve (V₂), and the mandibular nerve (V₃).

The foramen rotundum is a bony opening located in the sphenoid bone of the skull. It serves as a passage for the maxillary nerve (V₂), which is one of the branches of the trigeminal nerve. The maxillary nerve supplies sensory innervation to the maxillary teeth, upper gum, palate, and other structures of the face.

In summary, the foramen rotundum conveys a branch of the trigeminal nerve (CN V), specifically the maxillary nerve (V₂), which is responsible for sensory innervation of the face. The other listed foramina (foramen lacerum, optic foramen, and foramen spinosum) do not transmit branches of the trigeminal nerve. Therefore, the correct option is B.
