Answer:
In the examination of the embryological stages of various organisms, it appears to be very similar in their structure, for instance, all vertebrate embryos have gill pouch and that evolved in gills in fish and head and neck in others.
The tail of the vertebrates is also an example that is present during the embryological stage but later regressed in human and other have them. On this basis, it can be stated that embryology suggests an evolutionary relationship.

7. What is meant by the saying everything that is psychological is also biological
Answer:
People who work in psychology want to understand human behavior and where it comes from. The mind-body dualism debate is an ongoing discussion on whether or not the psychological activity of an individual is based entirely in their body, or if there is a higher consciousness separate from the body. The debate stretches back hundreds of years in the field of philosophy, where philosophers have argued whether everything is material, or if there is a separate, immaterial part to being human.

What is the difference between natural selection and artificial selection? Explain why?
Answer:
Natural selection is not decided by humans, but aritifical is. In natural selection, the organism that naturally survives will have their selection of characteristics carried onto the offspring. But in artifical, humans decide which characteristics they want from an offsrping for their sepcific need, e.g largest or colour and breed organisms for that characteristic- not to make them survive better.

Conduction is the transfer of heat between substances with different temperatures. Heat moves from the warmer to the cooler substance through direct contact.
Answer:
True.
Explanation:
Conduction is a heat transfer method. The heat passes by direct contact between two objects. The heat will go from the object with the higher temperature to the one with the lowest one. We call this temperature gradient. If we analyze the molecular aspect of conduction, we can see that the molecules with higher temperatures have more energy so, they move more. These molecules will collide with the molecules of the other object transferring their energy. As a result, heat passes from the hottest object to the cooler one till the two substances are at the same temperature, there is thermal equilibrium.

how do greenhouse effect allow for there to be life on earth? Explain
Answer:
A greenhouse effect is when a planets atmosphere gets thicker and warms
Explanation:
As a planet with water's parent star gets brighter every million years, The amount of evaporation increases. these are called greenhouse gasses. greenhouse gasses include water vapor and Carbon. This is why Venus is a burning hell. it was once like earth, but the sun kept getting brighter and brighter, causing clouds to form all over the rock, trapping in more heat, and making it far to hot for even metal. One day this will happen to earth, as well. this is why we have global warming. It can be caused by Co2 from earth's inhabitants and water vapor from it's vast oceans.

What conditions are necessary for rocks to melt? ( I’ll give a Brainliast) please answer
Answer:
The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
Answer:
Flux melting occurs when water or carbon dioxide is added to rock. These compounds cause the rock to melt at lower temperatures. This creates magma in places where it originally maintained a solid structure. Much like heat transfer, flux melting also occurs around subduction zones.

Cells of the amine system are able to respond to the presence of invading organisms because they recognize the
Answer:
Cells of the immune system are able to respond to the presence of invading organisms because they recognize the antibodies present in the invading pathogen
Explanation:
The mechanisms of human immunity can be grouped into two broad categories: the innate or nonspecific immune system, which provides a first and general defense against any element recognized as foreign, and the acquired or specific immune system that recognizes specific threatening agents and generates a response directed against those elements. When foreign substances enter our body (bacteria, viruses, parasites, proteins from other animal or plant species, cells from other organisms - including those of human origin - and a long etcetera, all of which are given the common name of antigens) and are brought into contact with cells that are members of the immune system, the foreign element or antigen is first captured by certain types of cells that are collectively known as antigen-presenting cells. These cells would correspond to the intelligence service and their mission is to take the antigens, introduce them inside, process them and present the antigens on their surface in a fragmentary way to other cells of the immune system. This results in the activation of lymphocytes that specifically recognize the antigen and ends in the development of mechanisms that mediate the physiological function of the response, that is, the elimination of the antigen. Thus, the immune response can be functionally divided into three phases: the antigen recognition phase, the activation phase of the response, and the effector phase.

Answer:
Explanation:
Genes contain specific instructions for how to make proteins within the body.
Epigenetic changes are generally heritable genetic changes that are due to environmental factors, which work by turning genes that already exist in the body 'on' or 'off' depending on these factors.
Meiosis produces gamete cells. This is usually a total of 4 gamete cells which are all part of producing everything required in the reproductive process.
exposure to extreme heat is probably the most likely cause of mutation for E. Coli as it needs a steady 36–40°C for survival.
Changes to body cells affect cell division. This is because genetic mutations cause cells that are designed for normal cell growth to greatly increase which can throw the system off and cause many problems.

Answer:8
Explanation:
Number of chromosomes in each body cell is 8.
What do you mean by chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Moreover, chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).
Therefore, passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

Hey y'all I need help with this bio question: what are the pros and cons of different skin tones in different parts of the world?
Heather and Matthew take 60 sec to walk eastward along a straight road to a store 90 m away. What was their speed?
Answer:
1.5m/s
Explanation:
Using the formula;
Speed (m/s) = distance (metres) ÷ time (seconds)
According to the information provided in this question, Heather and Matthew spend 60seconds to travel a distance of 90 metres. This means that t = 60s, d = 90m
Hence,
Speed = 90/60
Speed = 3/2
Speed = 1.5m/s.

if the checkpoint finds an error, what are some actions the cell can take to ensure the error does not get replicated?
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA. If the damage is irreparable, the cell may undergo apoptosis, or programmed cell death 2.
Explanation:
um i think this is correct. hope this helps and have a nice day
-KindnessMatters-
The cell cycle is the intricate process of replication of genetic material and producing the daughter cells. The cell cycle is regulated by several mechanisms, one of which is checkpoints.
Checkpoints are the sites where the cells are checked for errors and inaccuracy in the cell.
The cell takes action to ensure errors are not replicated as:
The G1 checkpoint in the cell cycle is the primary checkpoint, which decided whether the cell should divide or not divide. It checks for size, DNA damage, and nutrients. The cell cycle will halt if there will be any errors. The G2 checkpoint is involved in the overall smoothening of the cell cycle. If any damage is observed after the other checkpoints, the cell cycle will pause in the G2 phase, halting the replication of errored genetic material.The M checkpoint corresponds to accurate attachment of the sister chromatids and the cycle will be in pause if the proper attachment is not done.
Thus, there are several checkpoints to check the errors in the DNA, and if any error persists, the cell cycle will be halted.
