The genotype of an organism must therefore be homozygous recessive if it exhibits a recessive characteristic in its phenotype. Examples: If we come across a white guinea, its genotype should be “bb”.
What is the genotype of the guinea?A phenotype with juvenile hairlessness, weak skin, and age-dependent lung emphysema has been identified. The three genotypes may be distinguished, and the characteristic exhibits autosomal co-dominant inheritance.
The dominant allele H in guinea codes for the trait of having hair, whereas the allele H codes for the trait of not having any hair.
The guinea with the black coat is homozygous for the dominant allele if all of his or her progeny have black coats (BB). Heterozygous hybrids occur when guinea with black coats produce offspring that are half black coat color and half white coat color (Bb).
Therefore, it is false that the guinea you would be able to tell if its genotype were HH or Hh.

The statement that best describes the interphase of the cell cycle is as follows:
The Interphase is made up of the G1, S, and G2 phases and is the portion of the cell cycle where cellular contents are duplicated.Thus, the correct option for this question is B.
What is the Cell cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The cell cycle can be divided into two phases. They are as follows:
Interphase.M-phase (Division phase).Interphase is the first phase of the cell cycle that is again divided into three sub-phases.
G1 phase: It is the resting phase. This is because no synthesis of DNA occurs in this phase. It is involved in the synthesis of RNA and proteins. S-phase: During this phase, replication of DNA takes place along with histone proteins. So, it is also known as the synthesis phase. G2 phase: This is the second gap phase. In this phase, the synthesis of RNA and proteins continues.Therefore, the correct option for this question is B.

cellular energy?
A. passive transport
B.
active transport
C. osmosis
D. diffusion
Answers
Answer:
D Difusion......
help ...
Active transport requires the expenditure of cellular energy. Therefore option B is correct.
Active transport is a process that requires the expenditure of cellular energy, typically in the form of adenosine triphosphate (ATP).
In active transport, molecules or ions are moved against their concentration gradient, from an area of lower concentration to an area of higher concentration.
This movement against the concentration gradient requires energy to be expended by specific carrier proteins or pumps embedded in the cell membrane.
These pumps actively transport substances across the membrane, maintaining concentration gradients and facilitating the uptake of essential nutrients or the removal of waste products from the cell.
Passive transport, osmosis, and diffusion, on the other hand, do not require energy as they occur spontaneously along concentration gradients.
Therefore option B Active transport is correct.

Describe 2 adaptations that allow humans to be bipedal
Answers
Feral pigs are an invasive species commonly found in the Pineywoods of East Texas. Areas where feral pigs are found often have damaged farmlands, grass, and tree roots. When the pigs live close to water sources, their presence erodes the soil. This disrupts the native vegetation and makes those plants vulnerable to invasive plant species. There are no known predators to feral pigs.
How will the removal of the feral pig affect existing populations in that ecosystem?
A- Removing the pigs will not affect the ecosystem because the pigs have no natural predators that will be affected by their removal.
B- Removing the pigs will cause an increase in native plant populations over generations because the pigs will no longer damage the land.
C- Removing the pigs will cause the native vegetation to become quickly overgrown because the plants will no longer be the prey of the pigs.
D- Removing the pigs will cause an increase in invasive plant populations because the pigs were the only organism eating invasive plants.
Answers
Answer:
B.
Explanation:
In the excerpt, it says that the pigs eat the native plants, and disrupt the land.
So by taking the pigs out of the ecosystem, it will result in the native plants growing again, and the land forming back to normal.
The statement (B) is correct. Removing the pigs will cause an increase in native plant populations over generations because the pigs will no longer damage the land.
What do you mean by native plants?They are plants that have been growing in a particular habitat and region, typically for thousands of years or longer. Also called indigenous, they are well adapted to the climate, light, and soil conditions that characterize their ecosystem.
Moreover, a native species is found in a certain ecosystem due to natural processes such as natural distribution. The koala, for example, is native to Australia. No human intervention brought a native species to the area or influenced its spread to that area.
Hence, native trees: Palash, Indian Coral tree, Sita Ashok, Indian cork tree, Neem, Peepal, Kadamba, Karanj. Native shrubs: Kanchan, Shankasur, Ratrani, Mehendi, Gulmehndi, Parijatak. Native seasonal flowers: Utricularia, Balsam, Eriocaulon, Smithia.

which of the following is different between covalent and ironic bonds
Answers
Answer: Ionic bonds are electrostatic in nature, resulting from that attraction of positive and negative ions that result from the electron transfer process; charge separation between covalently bonded atoms is less extreme.
Explanation:
Ionic bonds result from transfer of electrons, whereas covalent bonds are formed by sharing. In an ionic bond, one atom essentially donates an electron to stabilize the other atom. In other words, the electron spends most of its time close to the bonded atom. Atoms that participate in an ionic bond have different electronegativity values from each other. A polar bond is formed by the attraction between oppositely-charged ions. For example, sodium and chloride form an ionic bond, to make NaCl, or table salt. You can predict an ionic bond will form when two atoms have different electronegativity values and detect an ionic compound by its properties, including a tendency to dissociate into ions in water while In a covalent bond, the atoms are bound by shared electrons. In a true covalent bond, the electronegativity values are the same (e.g., H2, O3), although in practice the electronegativity values just need to be close. If the electron is shared equally between the atoms forming a covalent bond, then the bond is said to be nonpolar. Usually, an electron is more attracted to one atom than to another, forming a polar covalent bond. For example, the atoms in water, H2O, are held together by polar covalent bonds. You can predict a covalent bond will form between two nonmetallic atoms. Also, covalent compounds may dissolve in water, but don't dissociate into ions.

Answers
Answer:
The answer is Oxygen .. so the name "oxidative phosphorelaton".
ETC is the part of cellular respiration to break sugar into energy. Oxygen is the final electron acceptor in the ETC of the cellular respiration process. Thus, option c is correct.
What is ETC?ETC is abbreviated for electron transport chain. It is one of the steps of the cellular respiration process that is involved in breaking the sugar molecule and oxygen into carbon dioxide, water, and energy. It uses electron and protein complexes to move the ions.
The oxygen acts as the final acceptor of the electron in the ETC due to its high electronegativity and affinity that allows it to accept electrons which leads to the formation of water as the byproduct. This further proceeds to the oxidative phosphorylation step.
Therefore, option c. oxygen accepts electrons in ETC.

Why do we have different cells in our bodies if every cell has the same DNA?
A. Gene expression
B. Protein synthesis
C. Meiosis
D. Mitosis
Answers
Answer:
A. Gene expression
Explanation:
Every cell has the same DNA, but because of gene expression, we have different cells in our bodies.
Gene expression turns specific genes on and off, which makes each cell have a unique function with differences in things such as protein types.
Gene expression also leads to different cells in our bodies because it changes the function of certain cells.
For example, red blood cells and white blood cells have different functions because of different gene expressions.
So, A is correct.
Due to gene expression one have different cells in the bodies.
What is gene expression?It refers to the process by which a gene gets turned on within a cell to produce proteins and RNA. Each cell in the body possesses the same DNA, however, it is because of gene expression that one possess distinct cells within the bodies.
As it makes particular genes turn on and off, therefore, each gene exhibit distinct functions with variations in the things like kinds of proteins. The gene expression also results in the formation of distinct kinds of cells due to differences in the functions performed by them.
Like platelets and white blood cells exhibit distinct functions due to distinct gene expressions. Thus, the correct answer is option A, that is, gene expression.

Answers
Answer: There are three stages of interphase: G1 (first gap), S (synthesis of new DNA ), and G2 (second gap).
Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied.
The cell grows and carries out biochemical functions, such as protein synthesis, in the G1 phase.
During the S phase, DNA is duplicated into two sister chromatids, and centrosomes, which give rise to the mitotic spindle, are also replicated.
In the G2 phase, energy is replenished, new proteins are synthesized, the cytoskeleton is dismantled, and additional growth occurs.

It is an important part of an ecosystem because at least 46 different species of insects visit the flower for food. The Arizona poppy has adapted to living in areas that receive less rain, but there are still periods of time that a drought occurs. What part(s) of photosynthesis would the plant not be able to perform if there were no rain? What would be the long-term effects on the plant if the drought continues? Explain your answer.
Answers
Answer:
See explanation
Explanation:
There are three main aspects of photosynthesis
(i) Absorption of light energy by chlorophyll.
(ii)Photolysis of water
(iii) combination of water and CO2 to form carbohydrates.
The second and the third aspects of photosynthesis are controlled by the availability of water. Plants absorb water from the soil through their root hairs and it moves up to the leaves by capillary action.
Hence, if there is no rain (drought), the soil will lack water and so does the plant thereby hindering the uptake of water for the second and third stages of photosynthesis.
the Arizona poppy, lie dormant during drought only to germinate, grow, flower, and yield seeds a few weeks after the rains return.

The phenomenon that is being described in this scenario is an eclipsing binary.
An eclipsing binary is a type of binary star system in which one star passes in front of the other, causing a periodic decrease in brightness as seen from Earth. This occurs because the star in front blocks some of the light emitted by the star behind it.
In an eclipsing binary, the period and depth of the eclipses can be used to determine the sizes and masses of the stars, as well as their distance from Earth. Therefore, eclipsing binaries are important tools for astronomers to study the properties of stars and their evolution.
