3. How would the bat population influence the number of cactus fruit that develop?
!!!!!!!!!!!!!!!!!!!!!!!!!
As the months pass, the table shows that the number of bats also causes an increase in the number of cactus flowers and fruit.
The cactus fruit don't seem to form in large number until the cactus flowers are also going up more in number. This is because pollination is necessary to form the fruit.
Based on this information:
The more bats in the population, the more pollination takes place, and the more cactus fruit is available as a result.
However, if the bats hit carrying capacity, they will be at a population number that is now bad for the number of cactus fruit, since there won't be enough food to feed the population- as more bats eat more fruit, the cactus isn't able to keep up with growing enough fruit to feed the bats at carrying capacity.

1. For a mutation to affect evolution, it must:
a. Provide a benefit to the organism
b. Involve more than one chromosome
c. Be able to get passed from parent or offspring
d. Be neutral—neither help nor harm the organism
For a mutation to affect evolution, it must provide a benefit to the organism. Hence option A is correct.
In order for a mutation to have an effect on an organism’s progeny, it must: occur in the next generation’s cells and affect the inherited material, impact the environment, and generate diversity among species.
They result in novel proteins that allow organisms to adapt to environmental changes. Mutations that are beneficial are necessary for evolution to take place. Mutations that enhance an organism’s ability to survive or reproduce are likely to increase in frequency over time.

gene
B) It increases the likelihood (chance) of passing genetic mutations to offspring
C) It replicates resistance genes in the cells of unhealthy individuals
D) It replaces a defective gene with a healthy gene
Answer:
D) It replaces a defective gene with a healthy gene
Explanation:
Gene therapy is the process of replacing defective genes with healthy ... genes to help the body fight or treat disease, or deactivating problem genes.
Whales, humans, lizards, and birds each have forelimbs that are adapted for different functions, including swimming, using tools, walking, and flying. While different in function, these forelimbs share a similar skeletal structure of the humerus, radius, and ulna. How does a comparison of the forelimbs of these organisms provide evidence for evolution?
A. These homologous structures indicate that these four organisms all share a common ancestor.
B. These analogous structures indicate that whales are descended from organisms that lived on land.
C. These analogous structures indicate that these four organisms all experienced convergent evolution.
D. These homologous structures indicate that humans, whales, and birds all evolved from a lineage of lizards.
Answer:
A. These homologous structures indicate that these four organisms all share a common ancestor.
Explanation:
Homologous structures mean the organs will have similar structure, but not necessarily function (human arm vs whale's flipper). While analogous structures are similar in function but not structure (wings of an airplane vs wings of a bird). Since the question states that they are similar in skeletal structure, we know they must be homologous structures, thereby eliminating B and C. D is not a choice because the question does not provide anything about the order of evolution. Therefore the answer is A. These homologous structures indicate that these four organisms all share a common ancestor.
* Which proces best explains how antibiotic resistance in bacteria can occur?

Recent research investigating variation in human height has found that a variety of genes at different loci, as well as early nutrition, influence height, especially the nutrition of a mother during gestation (the period of time during development of a fetus) and of a child during childhood years,. Given this information, which of the following is correct? (3 points)
For human height, the environment is more influential than inheritance of particular alleles.
One phenotypic trait is usually related to one gene.
Phenotypes are directly linked to genotypes and not influenced externally.
Phenotypes are usually the result of a combination of genes and influence of the environment. I think is D
Answer:
It's the fourth one:
Phenotypes are usually the result of a combination of genes and influence of the environment.
Explanation:
Genes and the environment both affect phenotype.
Phenotypes are usually the result of a combination of genes and the influence of the environment.
What is genes?
In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein.
During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gene–environment interactions. Some genetic traits are instantly visible, such as eye color or the number of limbs, and some are not, such as blood type, the risk for specific diseases, or the thousands of basic biochemical processes that constitute life.
Genes can acquire mutations in their sequence, leading to different variants, known as alleles, in the population. These alleles encode slightly different versions of a protein, which cause different phenotypical traits. Usage of the term "having a gene" (e.g., "good genes," "hair color gene") typically refers to containing a different allele of the same, shared gene.Genes evolve due to natural selection / survival of the fittest and genetic drift of the alleles.

A problem in my life that I have is when I am cooking. When I need to cook something on the stove I use butter on the pan so it won't stick. But getting out that block of butter and trying to cut a perfect slice of butter is always such a freakin hassle. So, a squeezable butter or a butter slicer mechanism that can use would be fantastic.
Or, how about when I use peanut butter. When I use peanut butter for like a PB and J I try to scrape the excess peanut butter back into the jar and whatevers left in the jar but then whats left on the knife is such a pain to wash off. so like a really good scrubber to help wash off peanut butter would be cool.

Which do solar flares and coronal mass ejections have in common? Select the two correct responses.
A. They appear as dark spots on the sun's surface.
B. They tend to occur during minimum points in the solar cycle.
C. They are caused by the sun's changing magnetic field.
D. They are explosive events that can affect Earth.
C. They are caused by the sun's changing magnetic field.
D. They are explosive events that can affect Earth.
Explanation:
I'm sorry if it is wrong but I am almost 100% that it is correct!
Have a good one!
The solar flares and coronal mass ejections are caused by the sun's changing magnetic field. Also they are explosive events that can affect Earth. The correct options are C and D.
What is solar flare?A solar flare is a massive explosion on the Sun caused by the sudden release of energy stored in 'twisted' magnetic fields.
However, not all solar flares are safe. While the Earth's magnetic field protects us from solar radiation, the sheer electromagnetic power of a flare disrupts power grids, internet connections, and other communication devices.
Ejections occur at varying rates depending on the phase of the solar cycle, ranging from about 0.2 per day near the solar minimum to 3.5 per day near the solar maximum.
Coronal Mass Ejections are large plasma and magnetic field expulsions from the Sun's corona.
The sun's changing magnetic field causes solar flares and coronal mass ejections. They are also explosive events that can have an impact on Earth.
Thus, the correct options are C and D as per the given scenario.

Answer: My theory was that they both were created at the same time. So if they both were created at the same time, then I guess that would solve this whole infinite loop thing. If the chicken came first, then it had to have come from an egg. So that means if the egg came first, where did that egg come from? A chicken. So its just a whole infinite loop.
