What features evolved over time in the different animal phyla ? 5 Animals That Have Evolved Rapidly
Guppies Adapted to Predators. ...
Green Anole Lizards Adapted to an Invasive Species. ...
Salmon Adapted to Human Interference. ...
Bedbugs Adapted to Pesticides. ...
Owls Adapted to Warmer Winters.
How did the features provide advantages that helped each group survive in their environment?
Examples of the basic adaptations that help creatures survive:
shape of a bird's beak,
the number of fingers,
colour of the fur,
the thickness or thinness of the fur,
the shape of the nose or ears.
it produces variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage. a disease or change in environment is less likely to affect all the individuals in a population.
Animals develop a certain feature in their body, which denotes the natural selection condition which helps them for survivorship. For, example bedbugs adapted to pesticides
How evolution in animal phyla and classes helps with adaptation?There are several features developed in the animal phyla, which make the animals adapt to their changing environment over time.
Guppies adapted to predators, if any organism adapted to its predators, it can increase the population of that organism. The shape of the bird's beak helps them to catch the food which is necessary for its survival in that environment.
Therefore, this condition tells about natural selection, for the better survival of the organism, it may occur to change their body conditions and their behavior to adapt to that conditions.

During the nineteenth century, biologists knew that South America and Africa
contained similar fossils. These fossils led them to believe that a temporary land
bridge between South America and Africa allowed ancient species to move
between both continents. In the twentieth century, evidence showed that South
America and Africa were once part of the same larger continent and that there
were no land bridges between them. How should biologists respond to the new
geological finding?

A man with a blood genotype IAi marries a woman with a blood genotype IAi. What phenotypes could be expected in their children? 1. Both type A and type O 2. Type O only 3. Type A only 4.Type B only
Answer:
1. Both type A and type O
Explanation:
Blood genotype in humans follow the ABO system. The allele iA (type A) and iB (type B) are co-dominant but both dominant over the allele i (type O). This means that only a human with two i alleles will be type O.
Type A - iAiA or iAi (heterozygous)
Type B - iBiB or iBi (heterozygous)
Type O - ii
In this question, a man with a blood genotype IAi (type A) marries a woman with a blood genotype IAi (type A). Each of the parents will produce a gametes iA and i. Using these gametes in a punnet square (see attached image), offsprings with the following genotype will be produced: iAiA, iAi, and ii.
iAiA and iAi are type A while ii is type O. This means that both type A and type O could be expected in the children of this cross.

To summarize what you have learned about transcription, explain how a gene directs the synthesis of an mRNA molecule. Include in your explanation the words and phrases: base-pairing rules, complementary nucleotides, DNA, gene, mRNA, nucleotide, nucleus, and RNA polymerase
Answer:
Please find a detailed explanation of the process below
Explanation:
Transcription is the first stage of gene expression in living organisms in which a DNA sequence is used to synthesize a mRNA molecule. This process, which occurs in the NUCLEUS of eukaryotes and cytoplasm of prokaryotes, is catalyzed by an enzyme called RNA POLYMERASE.
- In the initial stage called INITIATION, RNA polymerase binds to the promoter of GENE and starts to unwind the double strand of the DNA sequence.
- The RNA polymerase, then, begins to add complementary NUCLEOTIDE bases following the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will pair with Thymine (Uracil in RNA) while Guanine will pair with Cytosine i.e. T-A, A-U, G-C etc. This stage is called ELONGATION.
- The last stage called TERMINATION involves the stopping of the process because the RNA polymerase has encountered a termination signal.

compare and contrast the passive and active cellular uptake of glucose molecules and ions
Passive transport does not require energy for the transport of molecules where active transport requires energy for transport.
Active transport VS passive transport A glucose is a large molecule so its diffusion across a membrane is difficult that's why it diffuses across membranes through facilitated diffusion against the concentration gradient.While on the other hand, Active transport is the movement of molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentrationso we can conclude that passive transport does not require energy for the transport of molecules where active transport requires energy for transport.Learn more about transport here: https://brainly.com/question/25802833

Explanation:
Answer:
hand-to-hand combat
a gun
heavy object (baseball bat or something like that)
Explanation:
I don't know what situation you mean, but if the person is caught off guard, the first defense mechanism is your own body, punches, kicks, stuff like that
If someone is attacking, there's a 50/50 chance that they will have a gun, in that case, the gun can be used on either side, the attacker or the attacked
If someone is attacking, it is also possible that heavy objects, baseball bats, table legs, pipes, are going to be used on either side.

The images show the stages of human development. At which stage does cell differentiation start?
Between the eighth and sixteenth weeks of pregnancy, the human fetal pituitary experiences cellular differentiation.
What is cell differentiation ?The process of cell differentiation is how dividing cells alter their phenotypic or functional type. It is likely that all cells originate from stem cells and acquire their functions as they develop. Stem cells are typically at the top of a hierarchical structure that represents cellular composition.
The transformation of a single-celled zygote into a multicellular embryo and then into the complex multisystem of several cell types that is a fetus is an illustration of cell differentiation.
Gene expression and cell differentiation can both be influenced by environmental variables. Available nutrients, salinity, and temperature, for example, are all elements that can alter gene expression in organisms.

explain why cells must divide rather than grow. explain how surface area and volume as well as transport across the cell membrane are related to cell size and homeostasis
Answer:
Cells must divide rather than grow in order to replace damaged cells and reproduce unicellular organisms. The surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. Along with this, cell transport helps cells maintain homeostasis by keeping conditions within normal ranges inside all of an organism's cells.

Answer:
1. Gravitational potential energy is the energy that an object has because of its height and is equal to the object's mass multiplied by its height multiplied by the gravitational constant (PE = mgh). Gravitational potential energy is greatest at the highest point of a roller coaster and least at the lowest point.
2. Kinetic energy is energy an object has because of its motion and is equal to one-half multiplied by the mass of an object multiplied by its velocity squared (KE = 1/2 mv2). Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point.
3.Initially, before the big bang, the universe-ball was at rest. Now, after the big bang, it is falling: light and matter exist, and they are moving. And yet, because of the negative energy built into the gravity field created by these particles, the total energy of the universe remains zero.
4. When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
5. When the skater is dropped onto the ramp from above, the potential energy decreases and the kinetic energy increases. Every time the skater bounces from the impact, thermal energy is gained, and both potential and kinetic energy are lost.
