Answer:
May be Nutritional but no sure
Diet and stress are mostly examples of nutritional type of factors. Thus, option C is correct.
What is the example of Diet and stress?
Diet and stress are mostly examples of Nutritional factor, Eye color is mostly caused by Genetics. The structure of human eye is an important sensory organs which is responsible for vision, differentiation of color that is 10 – 12 million colors and maintain the biological clock of the human body.
The internal components of an eye are Lens which are transparent, biconvex attached to the ciliary body with the cornea it refracts light. Retina is the innermost layer of the eye, light sensitive and acts as a film of a camera, ganglion, bipolar and photoreceptor cells are present in retina.
It involve in the conversion of the image into electrical nerve impulses used for the visual perception.Optic nerve located at the posterior portion of the eyes which carry all the nerve impulses from the retina to the brain for perception.
Therefore, Diet and stress are mostly examples of nutritional type of factors. Thus, option C is correct.

What best describes a high pressure system? Question 4 options: Warm, rising air that creates cloudy, rainy weather Warm, rising air that creates clear, sunny weather. Cool, sinking air that creates cloudy, rainy weather Cool, sinking air that creates clear, sunny weather
Answer:
a high pressure system : Cool, sinking air, that creates clear, sunny weather.
Explanation:
The characteristics of the high-pressure system is marked by the presence of the cold and sunny days as compared to those of the warm and low-pressure pressure regions of the world. The air is light and lifts up easily and hence leading to the formation of clouds and rainfall. As compared to the cold air mass that is dense and hence has low moisture contents.Una persona hala un trineo a lo largo de un espacio horizontal de 9 m la cuerda con que sa hala forma un ángulo de 60° con la horizontal y la fuerza para mover el trineo es de 125 N a. Calcular el trabajo realizado por la persona al halar el trineo
Answer:
978,75 Newton metro.
Explicación:
El trabajo realizado es de 978,75 Newton metro cuando la fuerza es de 125 newton, la distancia es de 9 metros y el ángulo es de 60 grados porque cuando usamos la fórmula del trabajo realizado obtenemos esta respuesta. La fórmula del trabajo es fuerza x desplazamiento x Sin (θ). θ muestra la dirección y el ángulo en el que se realiza la fuerza. Entonces, multiplicando todos estos valores obtenemos la respuesta para el trabajo realizado, que es 978,75 Newton metro.

The statement that can be used to describe DNA methylation is "A mechanism involving attachment of methyl groups to certain bases for the long-term inactivation of genes during development."
Option D.) is correct.
Define DNA methylation.DNA methylation controls gene expression by attracting proteins implicated in gene repression or preventing transcription factor(s) from binding to DNA. The pattern of DNA methylation in the genome varies during development as a result of a dynamic process that includes both de novo DNA methylation and demethylation.
DNA methylation is an epigenetic mechanism that happens when a methyl group is added to DNA, altering the function of genes and influencing gene expression.
It's a process that involves attaching methyl groups to specific bases in order to inactivate genes for a lengthy time throughout development.
So, the statement that can be used to describe DNA methylation is option D.)

Which is a unicellular fungus?
A Slime mold
B Mushroom
C Yeast
D none of these
Explanation:
Unicellular fungi are generally referred to as yeasts. Saccharomyces cerevisiae (baker's yeast) and Candida species (the agents of thrush, a common fungal infection) are examples of unicellular fungi. Example of a unicellular fungus: Candida albicans is a yeast cell and the agent of candidiasis and thrush.
The wing of a bird and the front limb of a mammal have a similar number and arrangement of bones. Which evolutionary relationship explains these similarities? A. The wing and front limb are homologous structures; each evolved from a common ancestor. B. The wing and front limb are analogous structures; each evolved from a common ancestor. C. The wing and front limb are analogous structures; each evolved independently. D. The wing and front limb are vestigial structures; one evolved from the other.
Answer:
A
Explanation:
The correct answer would be that the wing and front limb are homologous structures; each evolved from a common ancestor.
Homologous structures are organs of different organisms that look similar in structure but perform different functions on their respective owners. They are as opposed to analogous organs which look different on different organisms but perform similar functions on them.
An example of the homologous organ is the wing of birds and the fore-limbs of mammals which are both built on a five-digit plant, also known as pentadactyl plan. While birds use their wings to fly, the fore-limbs of mammals are adapted for grasping or walking. An example of the analogous organ is the wing of birds and the wing of insects. They both look structurally different but are both for flying.
The correct option is A.

Traits that are determined by more than one gene are called what?
- Seeds have many different forms. Some are lightweight and
are easily blown by the wind. Others are coated with burrs
and stick to animals' fur or are spherical and roll easily.
How is the survival of plants related to the form of seeds?
A-Seeds must germinate away from the
parent plant in order to have access to
enough light and moisture.
B-Seeds with unusual forms are not
attractive to animals, so they are not
eaten.
C-Seeds are camouflaged within the
parent plant so that they are not eaten
by insects.
D-Seeds are designed to germinate when

This picture below shows the fossil of three species of mosasuar, large marine reptiles that are now extinct what do similarities in these mosasaur indicate
The similarities in the fossil fuels of the given species of the mosasaur indicates a close relationship between the organisms.
The fossil records of the extinct organisms are used for studying the characteristics of their genome and it also helps to understand the similarities and differences between the different species of the same organism which have become extinct.
Several fossil records of thousands of organisms have been recovered and studied by the paleontologists till date. The study of these fossils have suggested that the organisms that have become extinct were very different from the organisms that are found to be present today.

to contain the egg and ovule
to surround the flowering bud
to protect the reproductive parts of the flower
Answer:
to attract pollinators
Explanation:
The role of structure A is to attract pollinators. Pollinators are the organisms which helps in the pollination of flowers. These organisms gets nectar from the flower. During their contact with flower pollens are attached to their body and when they moves to another flower these pollens falls on the carpel of the flower and as a result pollination occurs that leads to formation of seed.
