Answer:

the correct answer is - a slight difference in factors and their mechanism of transcription such as Nucleotides, polymerase enzyme, and promotor regions.

Explanation:

All types of organism species have exact same nucleotides in their mRNA and DNA. Transcription is also initiated with the similar type of the promotor region in all species.

Slightly differences in any of these or mechanisms can be useful and help to create an evolutionary phylogenic tree or cladogram in various species. The polymerase enzyme is also similar in the various species.

Thus, the correct answer is - a slight difference in factors and their mechanism of transcription such as Nucleotides, polymerase enzyme, and promotor regions.

Kinase enzymes ______
soldier1979 [14.2K]

Answer:

Option D (4), add phosphate groups

Explanation:

Kinase enzymes are responsible for cellular activation. Protein kinase causes phosphorylation of specific amino acids by utilizing ATP as source of phosphate.

It adds phosphate groups (PO43−) and induces biological activity of biomolecules (such as proteins, lipids, and nucleic acids) by changing their conformation thereby activating them .

Human genome consists of several hundreds of kinase encoding genes which are involved in multiple phosphorylation reactions with in the cytoplasm of cells.  

Hence, Option D (4) is correct

PLZ HELP with this one!
Aleks04 [339]

Answer:

b) 50kg

Explanation:

You simply use F=ma equation, newtons second law

We are given: F=500N     a=10m/s^2    m=?

1) lets change F=ma to help us find the m, we divide both sides with the a so we get \frac{F}{a} =m

2) plug in the F and the a, \frac{500N}{10m/s^2} =m, where \frac{N}{m/s^2} =kg

3) plug it in ur calculator and you should get 50kg

hope this helped :)

Answer:Osteoblasts work in teams to build bone.

Explanation:They produce new bone called "osteoid" which is made of bone collagen and other protein. ... They regulate passage of calcium into and out of the bone, and they respond to hormones by making special proteins that activate the osteoclasts. OSTEOCYTES are cells inside the bone.

The Fact that organisms are adapted to survive in particular environments helps to explain why a. captive-breeding programs are
xxTIMURxx [149]

Answer:

The answer is C

Explanation:

Habitat destruction is the most cause of extinctions. As deforestation continues in tropical forests, it causes mass extinctions among organisms.

All species have specific food and habitat needs. The more specific these needs and the more localized the habitat, the greater the vulnerability of species to loss of habitat to agricultural land, livestock, roads and cities.  This is because the organisms are already adapted to the environment and any changes can prove disastrous for them.

In the future, the only species that survive are likely to be those whose habitats are highly protected, or whose habitat corresponds to the degraded state associated with human activity.
