Biology
1 answer:
Artemon [7]3 years ago
4 0

The reason why eukaryotic cells are in need of turning on and off their genes when necessary because of the reason that they may feel stress because they are under stress as they have the responsibility of acting immediately when they needed and by that, they need to be turned on or off in means of adapting to the stress that they experience.

Which property results from the crystal lattice structure of ionic compounds? A. low melting point B. good electrical conductivi
lions [1.4K]

Answer:

C.) crystalline solids

Explanation:

The solid materials may be crystalline or amorphous. The concept of crystal structure is related to the organization of atoms in a geometrical form. Crystalline structures are present in various materials, where atoms distributed within their structure form a network called the crystalline lattice. Therefore, crystalline structures have salts, metals and most minerals. Crystalline structures are formed by unit cells that are their basic unit, as they constitute the smallest set of associated atoms found in a crystalline structure.

The molecules of the crystalline structures can have two types of bonds, the directional ones, which include the covalent and dipole dipole and the non-directional ones where the metallic, ionic, van der Walls bonds. When formed by ionic compounds, these crystalline structures can result in crystalline solids.

Which two actions happen when bonds in ATP molecules are broken?
pochemuha

The ATP molecule is a high energy molecule. When a molecule of ATP breakdown, it produces chemical as well as thermal energy. The type of energy produced is mainly depends on the application for example, if the ATP breaks down to ADP, it produces thermal energy and if couples with a cellular process it produces chemical potential.

Our body needs energy to carry out cellular functions and the energy produced in a form of ATP is taken by cells to perform functions.

In cocker spaniels, black color (b) is dominant over red (b), and solid color (S) is dominant over spotted (s).
Levart [38]

Answer:

<h2>e) 3/4 </h2>

Explanation:

As given;

Black (B) is dominant over red (b), so B is dominant over b.

Solid (S) is dominant over spotted color(s), so S is dominant over s.

Offspring of BBss and bbss individuals are:

Gametes of parent BBss are Bs, Bs and gamete of bbss are bs, bs

offspring are : all Bbss

Cross between these offspring is; Bbss×Bbss

Gametes of parent Bbss are: Bs and bs  as given that the genes are linked.

Bs, bs × Bb, bs

Offspring are = BBss, Bbss, Bbss, bbss

Black spotted (B_ss) = 3/4
