6 0

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.

What are two types of molecules made in the smooth endoplasmic reticulum
Vadim26 [7]

Answer:

The two types of molecules synthesized by smooth endoplasmic reticulum is phospholipid molecules of plasma membrane and steroid hormone.

Explanation:

Endoplasmic reticulum is one of the most important organelle found inside the cytoplasm of eukaryotic cell.Endoplasmic reticulam is of two types

1 Rough endoplasmic reticulum contain ribosome on its surface which is responsible for the roughness of this endoplasmic retuculum.Rough endoplasmic retuculm help in protein synthesis.

2  Smooth endoplasmic reticulum does not contain ribosomes in its structure.Smooth endoplasmic reticulum is found in large amount in the testis ans ovaries of human.

     Smooth endoplasmic reticulum play a significant role in the biosynthesis of phos pholipid of plasma membrane along with the production of various steroid hormones such as testosterone.

Julio is studying the bald eagle, which has a binomial name of Haliaeetus leucocephalus. Using the modern system of
Lubov Fominskaja [6]

The kingdom is Animals. The genus is Haliaeetus. The species is leucocephalus are the statements which Julio can make about the bald eagle.

The option C is the correct answer.

Explanation:

Given that Bald eagle has binomial name as Haliaeetus leucocephalus.

Modern classification of binomial nomenclature is given by Carl Linnaeus.

From the modern system of classification the sequence is as kingdom, phylum, class, order, family, genus and species. The classification of bald eagle is:

Kingdom - Animalia

Phylum - chordata

class - Aves

Order- Accipitriformes

family - Accipitridae

Genus - Haliaeetus

species - leucocephalus.

The two word name of the species having genus first followed by species is binomial nomenclature which Julio has used for bald eagle as Haliaeetus leucocephalus.

Which is an example of genetic diversity within a rain forest? Question 15 options: all of the genes found within the ecosystem
Amanda [17]

Answer:

Option A, all of the genes found within the ecosystem

Explanation:

Genetic diversity is very essential to maintain the health of the population of any species. It includes all forms of alleles with in a specific species to ensure variability. Variability is essential to allow evolution of species through mating where species with more desirable genes mate to produce healthy offspring. Sub groups with in a species can also varying set of genes thereby making a gene pool.

Hence, option A is correct
