The answer to this question

Answer:

13. A group of Roaches moving in a group

14. Stepping on the Roaches to kill them

Answer: First image shows 3 groups with 14 Roaches in each group moving towards an human.

Second image shows the human stepping on the middle group of roaches.

Explanation: Roaches are nasty. Get an exterminator, ya nasty.

Answer:

0

Explanation:

Since the number 14 would be the value to have the strongest base in the pH scale, it would only make sense that 0 is the most acidic.

Answer:

Sandstone

Sandstone contains fossils of creatures such as trilobites, brachiopods, crustaceans, bryozoans and plants. Remains of land animals like mastodons and dinosaurs are much more likely to be found in sandstone.

The sneezing is release of air that helps the body to get rid of irritants in our nose and throat, like allergens, dirt, and dust.

Coughing is by forcing the air out of the lungs with high pressure, to clear the throat of these foreign particles.

Answer:

Metallic structure with black colour body.

Explanation:

The substance has metallic structure and black colour body will have greatest temperature among other substances because metallic structure and black colour of body heat up very quickly. Metals have free electrons which make it the best conductor of electricity and heat while on the other hand, black colour is a good absorbent which absorb heat very quickly so that's why we can say that metallic solids are the substance that have the greatest temperature.

Answer:

copper

Explanation:

it copper because it have less specific heat (j/kgoc)

eukaryotic glycocalyx is present in prokaryotic cells, eukaryotic cells can also have glycocalyces especially single celled eukaryotic organisms.

Answer:

The term extinction's dictionary meaning, is the process of when a species, plant, or any other term for animal family, goes extinct. In more, basic terms, it means when a certain species of animal dies out completely.

This can happen due to several reasons, some being massive natural disasters. Others die out due to an unknown predator entering an ecosystem in which it doesn't belong, therefore disbalancing it.

Examples of extinct animals are Dinosaurs, but their exact reason for going extinct is unkown, there are only theories.

There are also many animals in danger of going extinct, for example Bees.

Hope this information could be of use to you!

2 ) Fertilization

Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm are haploid, which means they each contain one set of chromosomes; upon fertilization, they will combine their genetic material to form a zygote that is diploid, having two sets of chromosomes. A zygote that has more than two sets of chromosomes will not be viable; therefore, to ensure that the offspring has only two sets of chromosomes, only one sperm must fuse with one egg.

In mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. When a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reaction, take place. In placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane. The fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. Fusion between the oocyte plasma membrane and sperm follows and allows the sperm nucleus, centriole, and flagellum, but not the mitochondria, to enter the oocyte. The nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome. This process ultimately leads to the formation of a diploid cell called a zygote. The zygote divides to form a blastocyst and, upon entering the uterus, implants in the endometrium, beginning pregnancy.

Process of fertilization: (a) Fertilization is the process in which sperm and egg fuse to form a zygote. (b) Acrosomal reactions help the sperm degrade the glycoprotein matrix protecting the egg and allow the sperm to transfer its nucleus.

To ensure that no more than one sperm fertilizes the egg, once the acrosomal reactions take place at one location of the egg membrane, the egg releases proteins in other locations to prevent other sperm from fusing with the egg. If this mechanism fails, multiple sperm can fuse with the egg, resulting in polyspermy. The resulting embryo is not genetically viable and dies within a few days.

Cleavage, the Blastula Stage, and Gastrulation

A zygote undergoes rapid cell divisions (cleavage) to form a spherical ball of cells: the blastula; this will further develop into a blastocyst.

Environmental designers are professionals who try to limit the effects of the building process on the surrounding environment when designing programs, plans, policies, buildings, commercial products, etc. They are capable of simultaneously providing ecological sustainability and pleasant human spaces. For that purpose, environmental designers can build structures by using environmentally friendly materials. Some of the most important areas of research that include the job of an environmental designer include ecology, sustainability, architecture, urban planning, construction, environmental impact, environmental psychology, etc.

The nuclear division that forms haploid cells, which is called meiosis, is related to mitosis. As you have learned, mitosis is the part of a cell reproduction cycle that results in identical daughter nuclei that are also genetically identical to the original parent nucleus.

Explanation:

The nuclear division that forms haploid cells, which is called meiosis, is related to mitosis. As you have learned, mitosis is the part of a cell reproduction cycle that results in identical daughter nuclei that are also genetically identical to the original parent nucleus.

Answer:

In general, mitosis (division of the nucleus) is preceded by the S stage of interphase (during which the DNA is replicated) and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components.

Explanation:

The different stages of Mitosis all together define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two genetically identical daughter cells.Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions. Homologous chromosomes are separated in the first division.

Answer:

Explanation:

Using the concept of de Broglie wavelength under relativistic conditions to determine the spatial limits for electron range.

de Broglie wave-length [tex]\lambda = \dfrac{h}{p}[/tex]

where;

h = plank's constant

p = momentum of particle which is expressed as:

[tex]p = \dfrac{\sqrt{k^2+2kmc^2}}{c}[/tex]

replacing the expression for (p) into [tex]\lambda = \dfrac{h}{p}[/tex], we have:

[tex]\lambda = \dfrac{h}{\dfrac{\sqrt{k^2 +2kmc^2}}{c}}[/tex]

[tex]\lambda = \dfrac{hc}{\sqrt{k^2+2kmc^2}} --- (1)[/tex]

here;

c = velocity of light = 3 × 10⁸ m/s

h = 4.13 × 10⁻¹⁵ eV.s

i.e.

hc = (4.13 × 10⁻¹⁵ eV.s)(3 × 10⁸ m/s)

hc = 1240 eV.m

The electron's rest energy (mc²) = 0.511 × 10⁶ eV

For the elctrons;

the minimum accelerated voltage = 40kV

the maximum accelerated voltage = 100 kV

the minimum K.E of the electron K = eΔV

K = e × 40 kV

K = 40 KeV

K = 40 × 10³ eV

From equation (1);

[tex]\lambda = \dfrac{hc}{\sqrt{k^2 +2kmc^2}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{(40 \times 10^3 \ eV)^2 +2(40 \times 10^3 \ eV)(0.511 \times 10^6 \ eV})}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{((1600000000) +(80000\times 511000))eV}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{((1600000000) +(40880000000)eV}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{(42480000000) \ eV}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{206106.769 \ eV}}[/tex]

[tex]\lambda = 0.062 \ nm[/tex]

[tex]\mathbf{\lambda = 6.20 \ pm}[/tex]

The maximum K.E of the electron K = eΔV

K = e × 10 kV

K = 10 KeV

K = 100 × 10³ eV

From equation (1);

[tex]\lambda = \dfrac{hc}{\sqrt{k^2 +2kmc^2}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{(100 \times 10^3 \ eV)^2 +2(100 \times 10^3 \ eV)(0.511 \times 10^6 \ eV})}[/tex]

[tex]\lambda = 0.037 \ nm[/tex]

[tex]\mathbf{\lambda = 3.70 \ pm}[/tex]

As a result, the spatial limits for the electron's range span from 6.02 pm to 3.70 pm.
