Explanation:
Many scientists favor the RNA world hypothesis, in which RNA, not DNA, was the first genetic molecule of life on Earth. Other ideas include the pre-RNA world hypothesis and the metabolism-first hypothesis. Organic compounds could have been delivered to early Earth by meteorites and other celestial objects. We can only speculate about these questions, since we haven't yet found any life forms that hail from off of Earth. But we can think in a more informed way about whether life might exist on other ...

Mr. Morales is teaching a lesson on classification. He says that spiders are classified as a different group than insects because they have eight legs instead of six legs. He explains that spiders evolved first. Mr. Morales also says that having eight legs is the derived trait that separates the two groups. Antonio thinks Mr. Morales is wrong. Which piece of information is Antonio considering?
A.Spiders do not have eight legs.
B.Insects do not have six legs.
C.If spiders evolved first, six legs is the derived trait.
D.Spiders do not have derived traits, since they evolved first.
Answer: The answer is C
Explanation:
The piece of information that Antonio is considering is that if spiders evolved first, six legs are the derived trait. So the correct option is C.
What are derived traits?A trait that has been observed in a group of organisms but was not observed or was absent in the previous common ancestor of the group.
These are also the traits that are not present in the group of organisms under consideration but were observed in the previous common ancestors. This is called the secondary loss of traits.
Therefore, derived traits are not only concerned with the development of new traits but also the loss of old traits. Simplicity in a structure or function is a secondary derived trait.
Thus, because the spiders evolved before other insects, the presence of 6 legs in insects is a secondary derived trait as it represents simplicity in structure. Spiders are not derived because they are the common ancestors of the group of insects.
Therefore the correct option is C.

Which of the following is conical movement in which the distal end of a structure moves in a circle and the proximal end remains relatively fixed?
A. Protraction
B. Rotation
C. Circumduction
D. Retraction
Answer:
The correct answer is OPTION C (Circumduction)
Explanation:
Circumduction is motions without clear opposites of the part of the body, an example is rotating the hand from the wrist. The answer is circumduction because this type of movement ensures the distal end of a bone moves in a circle while the proximal end remains relatively stable is particularly found in bones where the movements of the joints are opposite to each other example is the ball and socket joint movement. For circumduction to take place, the degree of distance between two bones of the body has to be decreased and sometimes straightened to increase the level of movement or motion produced, there must be a movement towards the middle of the body and sometimes joint movement away from the middle of the body. All these movements are in order.
this is regular science but the topic is introduction to body systems from the science book please someone help thanks
Answer:
1. Homeostasis
2. Organ system
3.The bones of the skeletal system serve to protect the body's organs, support the weight of the body, and give the body shape. The muscles of the muscular system attach to these bones, pulling on them to allow for movement of the body.
4.The nervous and endocrine systems are two forms of communication system in the human body that integrate, coordinate and respond to sensory information which is received by the human body from its surroundings
5.The skin functions by protecting the body from basic elements of nature such as water, UV sunlight and wind. ... However, skin in integumentary system acts by maintaining the internal conditions that is required by the body while it is excretory system because it secretes a fluid waste called sweat or perspiration.
6.In order to survive, cells must satisfy some basic needs such as oxygen, water, nutrients, waste removal, and maintaining of homeostasis. Oxygen and nutrients are necessary for different processes inside the cell. For instance, cellular respiration uses glucose and oxygen to form energy in the form of ATP.Water is important for different chemical reactions, as well. Also, the result of different processes, waste is produced and it is important to remove it from the cell. Finally, it is important that cell and whole body conditions do not vary so much and that homeostasis is maintained.
7.Ribosomes provide another good example of structure determining function. These small cellular components are made of protein and ribosomal RNA (rRNA). Their main function is to translate messenger RNA, or mRNA, into strings of amino acids called proteins.
8. the body is not in homeostasis from 7 to 10 hours. Explanation: The given graph shows homeostasis in terms of body temperature. The normal body temperature, that is 37 degrees C is maintained from 1 to around 6:45 hours.
9.There are several reasons why the body temperature falls continuously just like when you are exposed to an extreme cold weather or wearing wet clothing for a long time. This abnormality state of the body temperature can lead into some potential diseases and disorders like infection, insomnia, stress and sepsis

October 1, 2017 marks 27 years since the beginning of the Human Genome
Project. The goal of the group was to map the entire 3 billions bases and
80,000 genes in the human genome. On April 14, 2003, it was announced
that the goal was accomplished. Using this information, scientists have been
able to predict the risk of genetic diseases and understand the process of
inheritance. Which of the following statements best describes the process of
using the genetic code to produce polypeptides (proteins)?
Translation is used to produce a strand of RNA and proteins from a single strand of DNA.
O RNA produces a strand of DNA through transcription, then the DNA builds a protein molecule
through translation
O A single strand of DNA is used to make mRNA using translation, then the mRNA provides the
template for producing a protein through transcription
O A single strand of DNA is used to produce mRNA through transcription, then translation provides
the code for bonding amino acids to make a protein.
Answer:
The last one. A single strand of DNA is used to produce mRNA through transcription, then translation provides the code for bonding amino acids to make a protein.
Explanation:
Educated guess, but also. Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins.

Listen How are channel and carrier proteins similar? Select all that apply.
A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.
B. Channel and carrier proteins are both types of facilitated transport.
C. Channel and carrier proteins can only move substances in one direction either into the cell or out of the cell.
D. Channel and carrier proteins always move substances from the side of the membrane with the highest concentration to the side with the lowest concentration.
Answer:
a
Explanation:
A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.
Channel and carrier proteins are both types of facilitated transport.
Facilitated diffusion is one of the ways of transporting molecules and is characterized by the use of proteins that are inserted in the plasma membrane, such as ion channels and carriers or permeases.
Ions, amino acids and monosaccharides, among many other molecules, cannot cross the plasma membrane, because they are polar or are very large in size.
So, for the cell to obtain or eliminate these substances, the presence of transporter proteins is necessary.
This diffusion is a type of passive transport, because it takes advantage of the concentration gradient of the molecules and does not waste energy.
Ion channels are integral tunnel-shaped proteins, selective for one, two, or three ions. When a channel opens, ions flow under two principles: the concentration gradient and the electrochemical gradient.Consequently, when an ion channel opens, the potential difference between the two compartments is altered.
Transmembrane proteins mediate the transport of molecules such as bicarbonate or large, polar, uncharged molecules such as glucose.The transport through these proteins occurs in favor of the concentration gradient, and by a reversible conformational change of the proteins that allows the translocation of the molecule to the other side of the membrane.
This type of transport is always without energy expenditure and in favor of the electrochemical gradient, it occurs in the following way:
Uniport, a single molecule translocates in only one direction.Simporte, two molecules that translocate in the same direction.Therefore, we can conclude that channel and carrier proteins are both types of facilitated transport.

Do environmental or genetic factors affect growth of organisms most?
Answer:
Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. The environment in which an organism lives plays an important role in modifying the rate and extent of growth. Environmental factors may be either physical (e.g., temperature, radiant energy, and atmospheric pressure) or chemical. Organisms and the cells of which they are composed are extremely sensitive to temperature changes; as the temperature decreases, the biochemical reactions necessary for life occur more slowly. A lowering of the temperature by 10° C (18° F) slows metabolism at least twofold and often more.
I copied this stuff from a bunch of different biology websites. It doesn't answer your exact question but I would have to say based on what I typed here it would be the environment that affects the growth of an organism more.
