Answer:
Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
The extinction of a species is most likely to occur when environmental conditions change and the members of the species lack adaptive traits to survive and reproduce.
What do you mean by Species?Species may be defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.
If the members of species do not have adaptive traits to survive and reproduce, they will definitely become extinct in near future.
This is because the relative fitness is directly related to the appearance or existence of particular species in the habitat.
Therefore, the extinction of a species is most likely to occur when environmental conditions change and the members of the species lack adaptive traits to survive and reproduce.

What best describes a high pressure system? Question 4 options: Warm, rising air that creates cloudy, rainy weather Warm, rising air that creates clear, sunny weather. Cool, sinking air that creates cloudy, rainy weather Cool, sinking air that creates clear, sunny weather
Answer:
a high pressure system : Cool, sinking air, that creates clear, sunny weather.
Explanation:
The characteristics of the high-pressure system is marked by the presence of the cold and sunny days as compared to those of the warm and low-pressure pressure regions of the world. The air is light and lifts up easily and hence leading to the formation of clouds and rainfall. As compared to the cold air mass that is dense and hence has low moisture contents.A species of organism has survived in a mild environment for thousands for years.

The statement that can be used to describe DNA methylation is "A mechanism involving attachment of methyl groups to certain bases for the long-term inactivation of genes during development."
Option D.) is correct.
Define DNA methylation.DNA methylation controls gene expression by attracting proteins implicated in gene repression or preventing transcription factor(s) from binding to DNA. The pattern of DNA methylation in the genome varies during development as a result of a dynamic process that includes both de novo DNA methylation and demethylation.
DNA methylation is an epigenetic mechanism that happens when a methyl group is added to DNA, altering the function of genes and influencing gene expression.
It's a process that involves attaching methyl groups to specific bases in order to inactivate genes for a lengthy time throughout development.
So, the statement that can be used to describe DNA methylation is option D.)

A man who has type B blood has children with a woman who has type A blood. A. If they are both heterozygous for this trait, predict the possible blood types of their children. Punnett square:
Answer:
The possible blood types of their children are: type AB (iAiB), type A (iAi), type B (iBi), type O (ii)
Explanation:
Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but co-dominant. The following blood types are encoded by the following alleles:
Blood type AB - iAiB
Blood type A - iAiA or iAi
Blood type B - iBiB or iBi
Blood type O - ii
According to this question, a man who has type B blood has children with a woman who has type A blood. They are both heterozygous, meaning that the man's genotype is "iBi" while the woman's genotype is "iAi". Both parents will produce gametes as follows:
iBi = iB and i
iAi = iA and I
Using these gametes in a punnet square (see attached image), the following possible blood types are produced in the offsprings:
- type AB (iAiB)
- type A (iAi)
- type B (iBi)
- type O (ii)

What similarities in the development lead scientists to infer that opossums ,chickens, salamanders,and fish share a common ancestor?
The wing of a bird and the front limb of a mammal have a similar number and arrangement of bones. Which evolutionary relationship explains these similarities? A. The wing and front limb are homologous structures; each evolved from a common ancestor. B. The wing and front limb are analogous structures; each evolved from a common ancestor. C. The wing and front limb are analogous structures; each evolved independently. D. The wing and front limb are vestigial structures; one evolved from the other.
Answer:
A
Explanation:
The correct answer would be that the wing and front limb are homologous structures; each evolved from a common ancestor.
Homologous structures are organs of different organisms that look similar in structure but perform different functions on their respective owners. They are as opposed to analogous organs which look different on different organisms but perform similar functions on them.
An example of the homologous organ is the wing of birds and the fore-limbs of mammals which are both built on a five-digit plant, also known as pentadactyl plan. While birds use their wings to fly, the fore-limbs of mammals are adapted for grasping or walking. An example of the analogous organ is the wing of birds and the wing of insects. They both look structurally different but are both for flying.
The correct option is A.

Una persona hala un trineo a lo largo de un espacio horizontal de 9 m la cuerda con que sa hala forma un ángulo de 60° con la horizontal y la fuerza para mover el trineo es de 125 N a. Calcular el trabajo realizado por la persona al halar el trineo
Answer:
978,75 Newton metro.
Explicación:
El trabajo realizado es de 978,75 Newton metro cuando la fuerza es de 125 newton, la distancia es de 9 metros y el ángulo es de 60 grados porque cuando usamos la fórmula del trabajo realizado obtenemos esta respuesta. La fórmula del trabajo es fuerza x desplazamiento x Sin (θ). θ muestra la dirección y el ángulo en el que se realiza la fuerza. Entonces, multiplicando todos estos valores obtenemos la respuesta para el trabajo realizado, que es 978,75 Newton metro.
