Cytokinesis
The final stage of the cell cycle divides the cytoplasm and separates the cell into two individual daughter cells that are exact copies of the parent. In animals, the cytoplasm is drawn in until it is pinched in two. In plants, the cell plate gradually forms a membrane and cell wall separating the two daughter cells. Figure 3 shows the cell cycle with cytokinesis producing 2 daughter cells.

Answer:

- Rh, normal insulin

- Rh, no insulin

- Rh-, normal insulin

- Rh-, no insulin.

Explanation:

This question involves two genes; one coding for Rhesus factor and insulin product. The allele for Rh blood and normal insulin dominates that of Rh- and no insulin.

According to this question, if both parents are heterozygous for both Rh and normal insulin production and cross, i.e. RrIi × RrIi, the following phenotype of offsprings will be produced (see punnet square):

- Rh, normal insulin (R_I_)

- Rh, no insulin (R_ii)

- Rh-, normal insulin (rrI_)

- Rh-, no insulin (rrii)

A mineral is an inorganic solid that has an orderly internal structure. This means that atoms are structured in a certan specific way, giving the mineral unic properties. Also, a mineral has a defined chemical composition.

The first option can not describe a mineral because the rock formed when lava cools down does not have a specific structure and also it does not have a defined chemical composition, but it is a mixture of different components such as iron and magnesium.

The second option can not be describing a mineral because in this case also the atoms do not have the specifit arrangement of a crystal.

The third option is the onlyone that describes a mineral because the result of the process is a solid that has an orderly internal structure and a characteristic chemical composition. As the solution cools down the solute excess starts to form the crystal and the atoms are located in a specific arrangement

Xanthium and burdock seeds has spines and gets stuck to the body of animals or clothes of humans.

Plumule and radicle is part of an embryonal axis which gives rise to the root system.

Megasporophyll or Carpel is the whorl of a flower which has the female sex organs

Pistil is the female organ of a flower which consists of ovary, style and stigma.

Fertilisation is the process of fusion of male and female gametes in the ovules.

A carpel is the female reproductive organ of a flower that is part of the pistil. It is a hollow, vase-shaped structure that consists of an ovary at the base, a long, slender style, and a sticky stigma at the top. The ovary contains one or more ovules, which are the structures that develop into seeds after fertilization.

The carpel plays a crucial role in sexual reproduction of flowering plants. When pollen lands on the stigma it germinates and grows down the style to the ovary, where the male and female gametes unite to form a zygote. This process is called fertilization and leads to the development of a seed inside the ovule.

Different flowers have varying numbers of carpels, ranging from one to many, and they can be fused together to form a compound pistil. The carpel is essential for the production of fruits and seeds, which are important for plant reproduction and the continuation of the plant species.

Phenols and glycosides are pre-existing defense mechanisms in plants' immune systems. These compounds are part of the plant's chemical defense arsenal and are present in various tissues even before any attack or infection occurs.

Phenols are secondary metabolites found in plants that have antimicrobial and antioxidant properties. They contribute to the plant's defense against pathogens by inhibiting the growth and development of microorganisms. Phenols also play a role in wound healing and lignification, which strengthen the plant's cell walls.

Glycosides are another class of secondary metabolites found in plants that have diverse functions, including defense against herbivores and pathogens. Some glycosides act as toxic compounds when ingested by herbivores, while others can inhibit the growth of microorganisms or interfere with their feeding behavior.

Both phenols and glycosides are produced by plants as part of their constitutive defenses, meaning they are present at baseline levels even in the absence of stress or attack. However, their production can be further induced or enhanced in response to specific stimuli, such as pathogen invasion or herbivore feeding.

Answer: Structure

Explanation: Im pretty sure that the eggs from different living organisms may have different structures and features to it. Ofc there would be similarities but also differences in growth etc.

When we see the reciprocal cross between a red-eyed female (homozygous) and a white-eyed male,we observe that none of the offspring will have white eyes. Additionally, the sex of the offspring will be half male and half female since the ratio of males to females is 1:1.

The reciprocal cross for a red-eyed female (homozygous) and a white-eyed male can be shown as follows:Female (XrXr) x Male (XwY). Females have two X chromosomes and males have an X and a Y chromosome. Red eyes are dominant to white eyes; therefore, we use Xr to represent red eyes and Xw to represent white eyes.

The offspring are as follows:All F1 females are heterozygous (XrXw).All F1 males are hemizygous (XrY).The F1 generation will have red eyes since the dominant allele is present.

None of the F1 individuals will have white eyes as the recessive allele is not present in the F1 generation.

When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.

Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.

Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.

When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).

Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.

Answer:

answer!!

Explanation:

In the described experimental setup, information moves between organisms through visual observation and behavioral responses. Here is a breakdown of the information flow:

Visual Observation: The female cichlid fish in the central tank can observe the males in the tanks on either end through the transparent barriers. This allows the female to visually assess the males' characteristics, such as their size or coloration.

Behavioral Responses: Based on the visual information received, the female cichlid fish exhibits a mating preference by depositing eggs in the spawning nests that are closer to the larger male. This behavior indicates that the female is selecting the male with certain traits that she finds desirable.

The results of this experiment suggest that female cichlid fish have a mating preference for larger males. Out of the 20 repeated trials, in 16 cases, the females chose to deposit their eggs in the spawning nests closer to the larger male. This preference indicates that larger males may possess traits that are favored by the females during the mating process.

In terms of evolution, these results are consistent with the concept of sexual selection. Female cichlids choosing larger males for reproduction can lead to differential reproductive success. Larger males may possess genetic or phenotypic advantages, such as enhanced fertility, better parental care, or increased fitness. As a result, their genes have a higher chance of being passed on to future generations, leading to the evolution of traits that are preferred by females.

This experiment provides insights into the role of mate choice and sexual selection in cichlid fish, highlighting how the preferences of females can influence reproductive success and contribute to evolutionary processes.
