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.

Answer:
Explanation:
1 . 3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.
3 .Infiltration is the process by which water on the ground surface enters the soil. Infiltration is governed by two forces, gravity, and capillary action. While smaller pores offer greater resistance to gravity, very small pores pull water through capillary action in addition to and even against the force of gravity.
4.Water is removed from the surface of the Earth to the atmosphere by two distinct mechanisms: evaporation and transpiration. Evaporation can be defined as the process where liquid water is transformed into a gaseous state. Transpiration is the process of water loss from plants through stomata.
5.Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

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.)

The gravity of the Sun and Moon pulls earth's surface in opposite directions:
Answer:
The Moon's gravity pulls more on the planet than the water on the opposite side. These two water bulges on opposite sides of the Earth aligned with the Moon are the high tides. Spring tides occur when the Earth, the Sun, and the Moon are aligned, increasing the gravitational pull on the oceans.
The direction of gravitational pull of the sun and Moon on the earth surface occurs in the same and opposite directions depending on the time of the day.
Hello your question its quite vague but a general answer is provided above
The gravity of the Sun pulls the Earth towards itself while the gravity of the moon on the earth is strongest at side facing the moon.
The direction of gravitational pull of the sun and Moon on the earth surface occurs in the same and opposite directions. and this depends on the time of the day. at night when the moon is in-between the earth and the sun the direction of the gravitational pull is strongest on the side of the earth facing the moon which is in the same direction with the gravitational pull of the sun towards the earth.
while during the day the direction of the gravitational pull of the moon on the earth is strongest on the side of the earth facing the moon which is in opposite direction to the gravitational pull of the sun on the earth.
Hence we can conclude that The direction of gravitational pull of the sun and Moon on the earth surface occurs in the same and opposite directions depending on the time of the day.

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.

true or False? Bacteria are not organisms because they have no organs.
Answer:
i think it is false?
Explanation:
sorry if wrong
Bacteria are organisms, although they are unicellular and do not have organelles like multicellular organisms. So, the given statement is False.
What is Bacteria?Microorganisms which are unicellular, prokaryotic, and have a straight cell structure are known as bacteria. They are present in almost every part of the planet, including soil, water and the human body. Many ecological and biological processes, such as nutrient cycling, decomposition, and symbiosis, depend heavily on bacteria.
While some bacteria can cause disease, many others, such as those that live in the gut and support digestion, are helpful and important for maintaining human health. Bacteria can vary in shape, size, and structure, and they can be divided into several categories according to these characteristics.
Therefore, the given statement is False.

The diagram represents part of a process that occurs in cells.
Which cellular process must occur before the one illustrated above?
Select one:
a. meiosis
b. replication
c. transcription
d. translation
Answer:
C. Transcription
Explanation:
The diagram shows translation, where mRNA is translated by a ribosome to create a specific amino acid sequence.
Transcription must occur before translation, because it is the process where mRNA is made.
In transcription, mRNA is transcribed from DNA, then it is sent out of the nucleus and into the cytoplasm.
Then, the mRNA goes to a ribosome in the cytoplasm, allowing for translation to occur.
So, the correct answer is C. Transcription
