period between two periods of mitosis
the process involving the division of the nucleus in a
reproductive cell
Answer:
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.

Match the hominin with the best description.
Late Pleistocene hominins found only in Europe, Western Asia, and Central Asia; the Shanidar site belongs to this group.
Middle Pleistocene hominin; found in Africa, Asia, Europe; shows a mixture of features from previous and later hominins.
Answer:
- Late Pleistocene hominins found only in Europe, Western Asia, and Central Asia; the Shanidar site belongs to this group: Neandertals
- Middle Pleistocene hominin; found in Africa, Asia, Europe; shows a mixture of features from previous and later hominins: Homo_heidelbergensis
Explanation:
Neandertals represent an extinct hominid lineage and the closest evolutionary relatives of humans. Neandertals lived in Europe, Central Asia, the Middle East and western Siberia. This group of extinct hominids appeared around 130,000 years ago until their extinction, approx. 40,000 years ago. On the other hand, Homo_heidelbergensis is an extinct group of Homo_Hominids who lived during the Middle Pleistocene, a time period spanning 780,000-120,000 years ago. Homo_heidelbergensis is considered the most recent common ancestor between H. sapiens (modern humans) and Neanderthals. This species (Homo_heidelbergensis) combined primitive features (e.g., a wide face, and thick arching brow ridges) with modern features (e.g., a large brain capacity).

Explanation:
Transmission electron microscopes that use high-energy electrons accelerated over a range from 40.0 to 100 kV are employed in many applications including the study of biological samples (like a virus) and nanoscience research and development (alloy particles and carbon nanotubes, for example). What would be the spatial limitation (in pm) for this range of electrons
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.
What are the possible gametes (sperms) that would be produced from a male carrying balanced translocation between chromosomes 11 and 22, if it occurs in 2:2 Segregation: adjacent segregation
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.
image
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.

What is extinction ?
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.
