Which statement accurately describes binary star systems?
They have more than two stars.
They have stars that are always visible.
They include large groups of stars.
They have stars that might appear to wobble.
Answers
Answer:
The correct answer is D.They have stars that may appear to wobble.
Explanation:
Binary star - Wikipediaen.wikipedia.org › wiki › Binary_star
''Astronomers have discovered some stars that seemingly orbit around an empty space. Astrometric binaries are relatively nearby stars which can be seen to wobble around a point in space, with no visible companion. The same mathematics used for ordinary binaries can be applied to infer the mass of the missing companion''

What is the advantage of these different feeding niches for the birds?
A
less competition for food
B
fewer abiotic resources for each bird species
с
fewer biotic resources for each bird species
D
less energy available as the birds feed higher in the tree
Answers
Answer: it's D
Explanation: As more birds feed higher in the tree, available energy increases. More abiotic resources are available for each bird. Predators are less likely to feed on birds in a variety of locations.
The advantage of different feeding niches for the birds species is the less competition for the food and other resources. Thus, the correct option is A.
What is the advantage of feeding niches?Animals can occupy the same ecosystems, but will not have the same niches. The feeding habits and the other adaptations determine niche of an animal within its ecosystem. For example, cheetahs and lions have different hunting styles, thus are able to coexist in the same habitat.
If any two species can have the exact same niche, then they would be in direct competition for the resources with each other. If the competition occurs, then one species will outcompete the other species. If the losing species does not adapt to the change, this may lead to its extinction.
As more and more birds feed higher in the tree, the available energy for the species increases. More resources will be available for each bird niche.
Therefore, the correct option is A.

Gene expression can occur at several points along the pathway from DNA to RNA to proteins. In one example of gene expression, the protein insulin must be trimmed to a smaller size.
How is this is an example of gene expression?
A. until the protein is trimmed, it is not useful to the cell
B until the protein is trimmed, transcription is blocked by repressor protein
C. until the protein is trimmed ribosomes are not active
D. until the protein is trimmed the shape of DNA blocks transcription
Answers
Answer:
A. until the protein is trimmed, it is not useful to the cell
The trimming of protein insulin to a smaller size represents an example of gene expression until it is trimmed, it is not useful to the cell. Thus, the correct option for this question is A.
What is gene expression?Gene expression may be characterized as a type of biological process through which a gene gets turned on in a cell in order to make RNA and ultimately proteins. With the help of this process, information from a gene is used in the synthesis of a functional gene product that enables it to produce end products.
The process of gene expression consists of two major steps: transcription and translation. During the process of transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA in the cell nucleus.
While the process of translation involves the mechanism through which RNA is converted into amino acids through which functional proteins are constructed.
Therefore, the trimming of protein insulin to a smaller size represents an example of gene expression until it is trimmed, it is not useful to the cell. Thus, the correct option for this question is A.

Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. The haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures. Fusion of the male and females gametes forms the diploid zygote, which develops into the sporophyte.

How could our baby be an albino?
Tiffany and Joe have just had a baby and are very surprised to learn that their baby is albino with very pale skin
and hair color. Tiffany's sister has come to see the new baby, so Joe goes out to talk with his sister Vicky.
Did Tiffany have an affair?
Joe is very angry. He tells Vicky, "I think Tiffany had an affair with Frank! He's the only albino we know.
Obviously, Tiffany and I aren't albino, so Frank must be the father."
Luckily, Vicky remembers her high school biology, so she explains, "Two parents with normal skin and hair
color can have an albino baby, if they are heterozygous and carry a recessive allele for albinism."
She draws a Punnett Square to show this. Draw the Punnett Square. Use A for the dominant allele that
results in normal skin and hair color and a for the recessive allele that can result in very pale skin and hair color
Upload an image of your Punnett square.

Answer:
If both parents are heterozygous, there is a 1/4, 25%, 0.25 chance that the baby turns out albino.
