Answer:
D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species
Explanation:
During meiosis, the homologous chromosomes separate and segregate independently of each other. This process is referred to as 'independent assortment'. In consequence, different gene variants or 'alleles' localized in homologous chromosomes segregate independently of each other during gamete formation, thereby one particular gamete has an equal probability to carry either of these segregating alleles. Independent assortment generates genetic variation in the gametes, which can be beneficial or deleterious in a given environment.
The option that best describes how independent assortment results is D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species
What is independent assortment ?Independent assortment is a phenomenon that occurs during meiosis, which is the process of cell division that produces gametes (sex cells). During meiosis, the chromosomes are randomly sorted into the gametes. This means that the alleles (different forms of a gene) on different chromosomes can be inherited together or separately.
This random assortment of alleles can lead to new combinations of traits, which can be beneficial or harmful to a species.

why doesn't the periosteum cover the articular cartilage of a long bone
The periosteum does not cover the articular cartilage of a long bone because it is not located in the part of the bone where the joint is formed.
The main function of articular cartilage is to facilitate the movement of a joint in any mechanical circumstance.
The periosteum is a membrane that is part of the constitution of the bones, and that is located throughout the entire bone body, with the exception of the area that is destined for the articular surface.
It is found throughout the central part of the bone, that is, it passes through the entire diaphysis and reaches the metaphysis.
It disappears in the epiphysis because it is the area that generates contact with the tissues that make up the joints, necessary for movement.
Therefore, we can conclude that the periosteum is a membrane that covers all the bones, except the area that is destined for the articular surface.

ability of a cell to form the whole organism
Answer:
Totipotency
Explanation:
Totipotency can be regarded as
capability of single cell to divide,develop as well as to form differentiated cells in a living body. This could be found in Meristematic plant cells since they posses the ability to develop into complete plants. Totipotent cells can be formed during sexual and asexual reproduction and these could include spores and zygotes. Some organism can experience totipotency in the sense that cells can dedifferentiate as well as regaining totipotency. Instance of this is plant cutting which used in growing an entire plant.

A In the electron transport chain, Oz is converted to CO2.
B Glycolysis splits sugar to produce pyruvate and FADH2-
C Electrons leave the electron transport chain in a molecule of water (H20).
D
Both B and C are correct.
The statement which is true about cell respiration is; Choice B: Glycolysis splits sugar to produce pyruvate and FADH2-
Definition of terms:
Cellular respiration is a process used by all living organisms to convert glucose into energy.
Cellular respiration is a collection of three unique metabolic pathways: glycolysis, pyruvate oxidation, the citric acid cycle, and the electron transport chain.
Glycolysis; This pathway is anaerobic and takes place in the cytoplasm of the cell. This pathway breaks down 1 glucose molecule and produces 2 pyruvate molecule. A process which releases FADH2- in the process.Pyruvate Oxidation: In eukaryotic cells, the mitochondria is the site of pyruvate oxidation. The release of CO2 is a characteristic of this step.The Electron transport chain: The electron transport chain is the final component of aerobic respiration and is the only portion of glucose metabolism that uses atmospheric oxygen.Electrons are rapidly transferred from one component to the next to the endpoint of the chain, where the electrons reduce molecular oxygen, O2 producing water in the process.

Describe at least two abiotic and two biotic factors found in this biome. (Desert Biome) How
do these abiotic factors interact with the biotic factors?
Abiotic: the sunlight and water.
Biotic: Plants and insects
Explanation:
Plants such as cactuses can absorb and conserve water in their roots and use the sunlight to grow taller
Insects such as Desert beetles can trap moisture in their thick exoskeletons so they are parched or burned by the sun. They sometimes bury themselves deep in the sand where it's cooler.

ANSWER
Fossil fuels are formed when biomass is covered by sediment, and the biomass experiences high temperature and pressure over time. The correct option is B.
What are fossil fuels?Coal, oil, and natural gas are fossil fuels formed from the remains of dead plants and animals that were buried in sedimentary rock layers millions of years ago.
Over time, these organic materials are subjected to high temperatures and pressure, resulting in the transformation of organic matter into fossil fuels.
These hydrocarbons migrate through the surrounding rock over millions of years and accumulate in underground reservoirs, where they can be extracted and used as energy sources.
Fossil fuel formation is a slow process that requires specific geological conditions such as the presence of sedimentary rocks, high temperature, and pressure.
Thus, the correct option is B.

Juan and Carol were studying invertebrates in biology. They knew that segmented or earth worms preferred a dark, moist habitat. During this lab, they would be investigating the responses of organisms called planaria or Dugesia tigrina. These were simple flatworms that still had a one-way digestive system and a very simple nervous system. Juan and Carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. They shined a light on the dish. Next, they removed the paper and placed a small amount of chicken liver at one end of the dish. They added a few large salt crystals to the water. Finally, they added drops of hot water to the cool water in the petri dish. Their results can be seen in the data table. According to their experiment, all BUT one conclusion is valid. A) Planaria are a fresh-water organism only. B) Planaria are consumers and may be carnivores. C) Planaria have specialized cells to detect light intensity. D) Planaria have specialized cells that detect temperature change. answer and you get all my points plzzz
Answer:
A) Planaria are a fresh-water organism only.
Explanation:
Planaria are a fresh-water organism only. Although the planaria moved away from the salt crystals, it may be because of the concentration of salt rather than its presence. There are both fresh water and salt water species of planaria. The other three conclusions are supported by the data.
Planaria are consumers and may be carnivores is the correct. Thus option B is correct
What is a planaria?
Planaria also called cross-eyed worms.
They are the tiny group of flatworms belongs to phylum Platyhelminthes.
They are free-living organisms in fresh water bodies.
The body are small, measuring around 3 to 15 mm , have a soft, leaf-shaped body covered cilia and spade-shaped head with two eyes
It is otherwise called as flatworms under the ancient class of Turbellaria which is in the branch of Platyhelminthes.
Planaria can sense and respond different stimuli like light where e eyespots can detect light and allow the organism to react to it.
It can sense Chemical by the help of their head regions allow them to smell.

In the oceans on either side of the Isthmus of Panama are 30 species of snapping shrimp, 15 species on the Pacific side and 15 different species on the Atlantic side. Species live at different water depths. Morphological and genetic data show that Atlantic and Pacific species that live at similar depths are sister species. Geological evidence indicates that the Isthmus of Panama started rising about 10 million years ago and the oceans were completely separated by the isthmus about 3 million years ago. If the isthmus indeed formed gradually, which of the following patterns of genetic differences is most likely in these species pairs?
A) similar percentages of difference in DNA sequences between all pairs of sister species
B) greater percentage of difference in DNA sequences between sister species that inhabit deep water than between sister species that inhabit shallow water
C) greater percentage of difference in DNA sequences between sister species that inhabit shallow water than between sister species that inhabit deep water
D) greater percentage of difference in DNA sequences among Atlantic species than among Pacific species
Answer:
B) greater percentage of difference in DNA sequences between sister species that inhabit deep water than between sister species that inhabit shallow water
Explanation:
The isthmus formed gradually. About 10 million years ago, the isthmus began to separate the waters from the bottom, and snapping shrimp individuals inhabiting the deepness were separated for the first time. Since their separation, both groups evolved according to their new environment and the pressures acting on them. They started to gradually differentiate from each other, probably suffering many mutations through the years.
About 3 million years ago, the oceans were completely separated by the isthmus, meaning that those animals inhabiting the shallowest areas were the last ones to separate from each other on each side of the isthmus. Since then, they probably also suffered many mutations that drove them to differentiation.
However, as animals inhabiting the shallowest areas were the last ones to separate and, considering the time-lapse between both divergences, the highest degree of genetic difference is expressed by the sister groups inhabiting the deepest areas. Being separated from each other for a much longer time than shallow animals gave them more time to suffer more mutations and differentiate more.
The sister species at the depth of the ocean possesses a greater difference as compared to the sister species in shallow regions. Thus, option B is correct.
Evolution is the process of inheritable changes in the species with natural selection. The species in the close generation have a higher level of similarity in the traits.
What is the relation between the sister species?The sister species are the ones with the similarity in the traits. Thus, have the same ancestors and exhibit a greater percentage of trait similarity.
Atlantic and Pacific species are sister species and have similarities in the DNA sequence.
The isthmus separation is formed later in the ocean. The species present at the deeper range are older and are evolved. The species in the shallow region have less evolution as they are separated later.
Thus, the sister species at the depth of the ocean possesses a greater difference as compared to the sister species in shallow regions. Thus, option B is correct.

mendels law of independent assortment
Answer:
Mendel's law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene. Let's look at a concrete example of the law of independent assortment.
