Men should not accuse women of not delivering a male child for them because they are not responsible for determining the gender of the child. It all depends on the fusion of chromosomes.
How zygote is formed?The Zygote is formed after the successful fusion of male and female gametes.
Women bear both XX chromosomes, while men bear one X and one Y chromosome. It is a biological phenomenon of fusing these sets of chromosomes and determining the gender of the child.
Therefore, it is well described above.

A DNA segment is changed from AATTAG to AAATAG. What type of mutation is this and what is its effect on the genetic variation of a population?
A.
The mutation is a substitution which causes a decrease in the genetic variation of a population.
B.
The mutation is an insertion which causes a decrease in the genetic variation of a population.
C.
The mutation is an insertion which causes an increase in the genetic variation of a population.
D.
The mutation is a substitution which causes an increase in genetic variation of a population.
The mutation from AATTAG to AAATAG is a substitution which causes an increase in genetic variation of a population.
MUTATION:
Mutation refers to any change in the nucleotide sequence of DNA molecule. Mutation can be of different types depending on how it occurs. A substitution mutation is that in which one or more nucleotide base is replaced by another in the sequence. In this question, an original sequence of DNA is given as AATTAG. It was mutated to AAATAG via the replacement of 'T' with 'A'. This means that it is a substitution mutation. However, this mutation will cause an increase in the genetic variation i.e. difference in a population.Learn more at: https://brainly.com/question/21220597?referrer=searchResults

Which compound is a reactant of both cellular respiration and dehydration synthesis? (1 point)
O glucose
O oxygen
O water
O ATP
Answer:
glucose
Explanation:
I had a test with this, and it was glucose.
Glucose is a reactant of both cellular respiration and dehydration synthesis
WHAT IS CELLULAR RESPIRATION?
Cellular respiration is the process by which living organisms obtain energy from organic sources. Cellular respiration combines glucose and oxygen as reactants to form carbon dioxide (CO2), water (H2O), and energy.WHAT IS DEHYDRATION SYNTHESIS?
Dehydration synthesis is a reaction whereby two smaller molecules come together to form a larger molecule with the loss of water. An example of dehydration synthesis reaction is the formation of starch from the reaction of glucose molecules with the loss of water.Therefore, glucose is a reactant of both cellular respiration and dehydration synthesis.

The body systems that would immediately get involved with my reaction to the cut are nervous system, circulatory system, integumentary system. That is option A
The systematic factors that are required for wound healing after sustaining a cut in the finger include:
The nervous system: here the nerve cells in the skin help wounds to heal. When an injury occurs, cells known as glial cells change into repair cells and disseminate into the wound, where they help the skin to regenerate.The circulatory system: The cut surfaces become inflamed and blood clot and cell debris fill the gap between them. Phagocytes from the blood stream, begins to remove the clot and cell debris stimulates fibroblast.The integumentary system: the skin contains extracellular matrix (ECM) which is made of collagen and elastic fibres that provide structure to the skin and are necessary for wound closure.Learn more here:

describe the human population growth curve over the past 10,000 years, and identify the type of population growth curve it represents
p.s I will give brainless
Explanation:
Global human population growth is around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012.
Although the direst consequences of human population growth have not yet been realized, exponential growth cannot continue indefinitely.
In the late 1970s, China’s “one-child” policy tried to control population growth, but restrictions were relaxed in the early 2000s.
In what organelle do the Kreb's cycle and the electron transport chain take place?
(1 point)
0. chloroplast
O mitochondria
O cytoplasm
o nucleus
Answer:
mitochondria
Explanation:
-The aerobic phases of cellular respiration in eukaryotes occur within organelles called mitochondria. These aerobic phases are the Krebs Cycle and the electron transport chain.
The Kreb's cycle and the electron transport chain take place in the MITOCHONDRIA.
Cellular respiration is an aerobic process, i.e., a metabolic process that requires oxygen (O2) by which energy from foods is used to synthesize ATP, carbon dioxide (CO2), and water (H2O). The three stages of cellular respiration are glycolysis, Kreb's cycle (also known as the citric acid cycle), and the electron transport chain.Glycolysis is an anaerobic pathway (i.e., does not require O2) and occurs in the cytoplasm.The Kreb's cycle and the electron transport chain (ETC) are both aerobic processes that occur in the intern membrane of the mitochondria.In conclusion, Kreb's cycle and the electron transport chain occur in the mitochondria.

an organism that invades a region can have negative consequences and not region what kinds of shifts can take place?
Invasive species provoke significant damages in the structure of native ecosystems. They also cause economical and socio-cultural problems.
------------------------------------
When talking about dispersion we refer to the change in a species´ range or distribution area.
When a species move and establish in a new area out of their original distribution range, they might be considered exotic or invasive, according to their
reproductive rate, population growth, and interaction with native species.The introduction of invasive species has ecological, economic, socio-cultural consequences. Once an invasive species has been established, it overgrows. In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their establishment. They interact with native species by competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-. They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species. They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.
As they expand, they can also affect human in an economical manner and has socio-cultural effects. Many invasive species might cause crops loss by eating cultures. They attack farm animals. They affect buildings and other structures or ships by eating wood. They might even attack humans and cause health problems.
