If a new species of honeycreeper were discovered, and it had a short, straight beak, which bird in this puzzle would likely be its closest living relative?
Answer:
The bird species that share the closest phenotypic characteristics are likely closest relatives.
Explanation:
Evolution theory states that species evolve gradually trough mutations (many of them are neutral), thereby those honeycreeper populations closest are more likely to share phenotypic features with each other.

Butterflies usually are identified by the colors and patterns on their wings. Butterflies have four wings: The two wings near the butterfly’s head are “forewings” while the wings near the butterfly’s tail are “hindwings.” You can use the following dichotomous key to identify four common butterfly species in North America.
The shown butterfly in the diagram is - Papilio polyxenes.
Butterflies usually are identified by the colors and patterns on their wings. To identify an organism using a dichotomous key, compare the organism’s traits to the first pair of descriptive statements on the key.
Follow the directions after each matching statement until you get to the organism’s identity.The points on the hindwings identify the butterfly as
a swallowtail butterfly is either Papilio glaucus or Papilio polyxenes.1. Hindwings rounded ………………… Goto 3
2. Wings mainly yellow …………… Papilio glaucus
Wings mainly black ………….. Papilio polyxenes
3. Wings orange with black piping…Danaus plexippus
Wings yellow with black edges….. Colias philodice
The wings are mainly black, so the butterfly is Papilio Polyxenes (common black swallowtail)Thus, the shown butterfly in the diagram is - Papilio polyxenes.

Which best describes genetic mutations?
A. Some inherited genetic mutations can be good for the offspring.
B. Different genetic mutations cause few forms of cancer.
C. Somatic mutations can be inherited from parents or acquired during life.
D.Genetic mutations that cause diseases are always passed on to offspring.
Answer:
A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo.
Explanation:
Some inherited genetic mutations can be good for the offspring.
What is mutation?"It is a change in the structure of a gene."Gene is a structural and functional unit of hereditary.It is caused due to addition, deletion or copying of single base pairs of DNA.The mutation that occurs in somatic cells (cell other than stem cells or s ex cells) are not transferred from parent to offspring.A mutation should occur in s ex cell, in order for it to pass down to the offspring. So, the mutation that cause disease if occurs in somatic cell will not be passed to the offspring.The mutation can sometime result in the production of new proteins that are beneficial in nature.Not all the genetic mutation can cause cancer.Hence, the correct option is A. Some inherited genetic mutations can be good for the offspring.

What is brain?
The part the nervous system that contains the cerebrum and cerebellum is the brain. The brain is an organ in the body that controls different other activities in the body. Almost everything in the body is controlled by the brain. The three main parts of the brain is; cerebrum, cerebellum, brainstem. The cerebrum controls speech and emotion, the cerebellum controls movement and the brainstem controls sneezing, coughing.
Spinal cord is a part of the nervous system transports information between the brain and other parts of the body. The spinal cord is a tubular and thin structure composed of nervous tissue. The spinal cord functions are to the transmission of neural signals among the brain and other parts of the body. Spinal Cord is necessary because the brain communicates with the body through it.
Thus, the brain sends information by the spinal cord to the peripheral nerves everywhere to the body that serves to regulate the muscles and inner organs.

A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life.

The body can be invaded by pathogens , which are harmful microorganisms that cause infection diseases. The body then initiates a(n) inflammatory response, which may involve redness, swelling, and fever.
Answer:The term "disease" refers to conditions that impair normal tissue function. For example, cystic fibrosis, atherosclerosis, and measles are all considered diseases. However, there are fundamentally different causes for each of these diseases. Cystic fibrosis (CF) is due to a specific genotype that results in impaired transport of chloride ions across cell membranes, leading to the production of abnormally thick mucus. Thus, CF is most accurately called a genetic or metabolic disease. Atherosclerosis, which can lead to heart attacks and strokes, may be considered a disease of aging, because it typically becomes a problem later in life after plaques of cholesterol have built up and partially blocked arteries. In contrast, measles is an infectious disease because it occurs when an individual contracts an outside agent, the measles virus. An infectious disease is a disease that is caused by the invasion of a host by agents whose activities harm the host's tissues (that is, they cause disease) and can be transmitted to other individuals (that is, they are infectious).
contrast homozygous and heterozygous genotypes? Dont copy from the internet please
Answer:
I got you
Explanation:
homozygous is when the letters are AA or aa NOT Aa
heterozygous is when it is Aa
The homozygous can only pass down A or a, not both. If the parent was AA, the probability of their offspring would be more likely to have a dom. phenotype is more likely. If it was aa, they are more likel to create heterozygous and recessive offspring.
The heterozygous coding is able to pass on both the recessive and dom. traits. So the offspring would be more dependent on the other parent, but most likely will have more dom. offspring.

Identify the types of breezes and the areas of high and low pressure that cause them.
Answer:
There are 4 types of breezes: land breeze, sea breeze, mountain breeze and valley breeze.
The breeze will originate from an area of high pressure and travel towards/blow in the direction of the area at a lower pressure.
In each case, the name of the breeze indicates where the breeze is blowing from. For instance, the land breeze will blow from the land (at high pressure) to the sea (at lower pressure). A mountain breeze will blow from mountain (at high pressure) towards the valley (at low pressure).
