How many genes make up the human genome?
four: adenine, thymine, guanine, and cytosine
23 pairs of genes
20,000–25,000 genes
3 billion genes

Answers

Answer:

The correct answer is - 20000, 25,000 genes.

Explanation:

Genes are made by the functional and physical unit of the heredity called DNA. Genes are the precursors or encoded instructions to make a specific protein. Genes can be small or large depending on the DNA bases present in it which can be hundreds to millions in numbers.

According to the Human Genome Project, which found out the total genes present in a human genome between 20000 to 250000 genes approximately.

Thus, the correct answer is - 20000, 25,000 genes.

Genes are the hereditary units, which are present in the coded segments of the DNA. Genes carry the information from parent to daughter cells.

There are 20,000 to 25,000 genes that make up the human genome.

Human Genome Project was conducted for several years, the result obtained was:

The human genome project was an international scientific project, which aimed at determining the base pairs that make up the human DNA.

The project estimated that humans consist of 20,000 to 25,000 genes in their genome. Each individual inherits the copies of genes from both parents.

Therefore, the correct answer is Option C.

Which best describes the permeability of a membrane?
O A. The total thickness of the membrane
B. The flexibility of the membrane
C. The number of molecules in the membrane
D. The ability to allow materials to cross a membrane

Answers

Answer:

D

Explanation:

D. is correct because the membrane works like a security guard and only allows certain materails to cross the membrane. The definition of permeability is the state or quality that allows something to pass through.

Permeability is a standard of easy motion of liquid and gases through a membrane or material. They allow the transportation and exchange of gases in a cell.

The statement that best describes the permeability of a membrane is:

Option D. The ability to allow materials to cross a membrane.

This can be explained as:

Permeability is a physical property of membranes and substances that allows the other molecules to move through them.

It acts as a barrier from substances entering and exiting the cell or membrane and maintains the balance in a system.

Therefore, permeability is the allowance of materials across the membrane.

Select an ecosystem that is familiar to you and describe the biotic and abiotic factors that exist there?

Answers

Answer:

Forest Ecosystem

An ecosystem is composed of two main components: biotic and abiotic factors. Biotic factors are the living parts of the ecosystem, such as plants, animals, insects, fungi, and bacteria. Abiotic factors are the non-living parts of the ecosystem, which influence the size and composition of the living parts: these are components like minerals, light, heat, rocks, and water.

Biotic Factors by Type

The most obvious features of any forest ecosystem are its trees, the dominant biotic feature. They dominate the ecosystem: both in terms of visibility and in terms of biomass. However, they are only one type of organism living in a forest. Other biotic factors include:

shrubs , flowering plants , ferns , mosses , lichens , fungi , mammals , birds , reptiles , insects , worms , microbes

Abiotic Factors by Type

The most important abiotic feature of a forest ecosystem may not be obvious, despite its ubiquity and importance: sunlight. Tangible abiotic factors include soil, minerals, rocks, and water. But abiotic factors can be intangible, such as temperature, other types of radiation, and the chemistry of soil and water.

Biotic Factors by Function

Ecologists frequently group an ecosystem's factors by what role they play in the system, rather than by what particular species they are. This is known as a functional classification.

These functions relate to the movement of energy through an ecosystem, and trees — along with other photosynthetic plants — are the chief primary producers. This means that trees convert the sun's energy into food energy, which is then used by other members of the ecosystem.

These other members of the ecosystem can also be categorized. Primary consumers are, for example, herbivores that eat the primary producers. Secondary consumers are the carnivores and omnivores that eat the primary producers. Decomposers are the scavengers, microbes, and fungi that consume the droppings and the carcasses of other organisms.

Abiotic Factors by Function

The abiotic factors of a forest fall less obviously into functional classifications, but keep in mind that the energy transferred among the various biotic categories is itself a foundational abiotic element. This energy occurs in the form of solar radiation, which includes both visible light and heat (infrared).

Primary producers (plants like trees and shrubs) convert the light into carbohydrates, a form of energy that can be consumed by other organisms. The function of other abiotic factors relies on the minerals they contain, such as the nitrogen in the soil or the hydrogen in water molecules.

An ecosystem consist of various biotic and abiotic factors which interact with each other. A grassland ecosystem is a terrestrial ecosystem which have grass as the main producers (dominant) living thing.

What is a Grassland Ecosystem?

A grassland ecosystem is a type of terrestrial ecosystem in which grasses and the herbaceous plants are the dominant species. Grass controls the grassland ecosystems as they are the main producers of the ecosystem with few or no trees where there is not favorable conditions for a forest. It is more like a dry and desert ecosystem. Therefore, it is also called as a transitional landscape.

The four important abiotic components of grassland ecosystem includes climate, parent material and soil, topography, and natural disturbances. Climate includes the rainfall pattern, temperature and wind patterns of a particular area.

Biotic Factors in the Grassland ecosystem include Plants, Insects (Invertebrates), Grazers, and Predators.

O A. If seed shape did not have a clearly recessive form
B. If having a smooth seed had been a dominant trait
C. If having a wrinkled seed had been a recessive trait
D. If garden peas produced large numbers of offspring​

Answers

Answer:

A. If seed shape did not have a clearly recessive form

Explanation:

To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.

For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.

A. If seed shape did not have a clearly recessive form.
