Cells communicate in ways that resemble human communication. Decide which of the following forms of human communication are analogous to autocrine, paracrine, endocrine, and synaptic signaling by cells. A. A telephone conversation B. Talking to people at a cocktail party C. A radio announcement D. Talking to yourself - autocrine
Answer: Option A.
Telephone conservation.
Explanation:
It is telephone conservation because it is analogous to synaptic signalling because it involve a personal conversation between a person who is far away or very distant and both the communicator and the recipient are able to receive message between each other or they are able to communicate their thought which is synonymous to synaptic signalling.
Cells connect to each other to communicate to each other over long distance through these three main ways and they are gap junctions, tight junctions, and desmosomes.

What global climatic change gave gymnosperms an advantage over ferns?
A) Increased fluctuations in global climate
B) the climate becoming hotter and wetter
C) the climate becoming cooler and drier
D) the climate becoming hotter and drier
The climate becoming hotter and drier which is the global climatic change gave gymnosperms an advantage over ferns. So, the correct option is D.
What are Gymnosperms?In contrast to angiosperms, or blooming plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms are described as any vascular plant that reproduces by an exposed seed, or ovule. Many gymnosperms bear their seeds in cones, which are known as "uncovered seeds" because they are not visible until they are fully developed.
Pinophyta, Cycadophyta, Ginkgophyta, and Gnetophyta are the four classes of gymnospermous plants, having 88 genera and more than 1,000 species among them. Gymnosperms have an advantage over ferns as a result of the temperature growing hotter and drier as a result of global climate change.
Therefore, the correct option is D.

caleb has a double row of eyelashes that he inherited from his mother as a dominant trait. His maternal grandfather is the only other relative to have the trait . veronica, a women with normal lashes, falls madly in love with Caleb, and they marry. Their first child , molly, has normal eyelashes. Now veronica is pregnant again and hopes they will have a child with double eyelashes. what chance does their child have of inheriting a double row of eyelashes
Answer:
1/2 or 50%
Explanation:
From the illustration, the double row of eyelashes is a dominant trait.
Caleb inherited his double row eyelashes from his mother, meaning that Caleb is heterozygous.
Assuming that the allele for double eyelashes is represented by D, Caleb's genotype would be Dd.
Veronica has normal eyelashes, her genotype would be dd.
Dd x dd
Progeny Dd Dd dd dd
Probability of double eyelashes = 1/2 or 50%
Probability of normal eyelashes = 1/2 or 50%
Hence, the chance of their child inheriting a double row of eyelashes is 1/2 or 50%.
You want to prepare a 1:50 dilution of your protein extract in a total volume of 1000 uL. You will need ___ uL of protein extract and ___ uL of water.
I’ll mark the brainliest!!
Answer:
20uL of protein, 980uL of water
Explanation:
According to the question, a protein extract is about to be prepared using a 1:50 dilution of the extract in a total volume of 1000uL.
1:50 means there will be;
1/50 part of protein and 49/50 part of water.
Hence, in a total volume of 1000uL, one would need:
Protein extract: 1/50 × 1000 = 20
Water: 49/50 × 1000 = 980
Therefore, 20uL of protein and 980uL of water will be needed to make a 1000uL solution containing protein extract and water in the ratio 1:50

A transgenic mouse animal model is created that expresses both the Cre recombinase gene, under control of a promoter for a gene expressed only in muscle fibers, and an androgen receptor with loxP sites around exon 2. How will expression of the androgen receptor protein be altered in the transgenic mouse
Answer:
The Cre-lox system triggers recombination of the androgen receptor gene in muscle cells
Explanation:
The Cre-lox system is capable of producing site-specific recombination events in a given DNA region. This technique enables the spatial and temporal control of target gene expression. The Cre-lox system contains a recombinase enzyme (Cre recombinase) that allows the recombination of specific nucleotide sequences (LoxP sequences), being thus used to produce genetic modifications (i.e., insertions, deletions, translocations, inversions, etc.) at target loci where LoxP sequences were inserted.

Living things should not be viewed under a(n) _____ because the preparation process would kill them.
Answer:
Electron Microscope
Explanation:
In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power. The method used to prepare the specimen for viewing with an electron microscope kills the specimen. Electrons have short wavelengths (shorter than photons) that move best in a vacuum, so living cells cannot be viewed with an electron microscope.
Answer:
Electron microscope

Which visualization best helps the reader see the relationship between the two variables temperature and radiation why
Answer:
The correct answer is - scatter plot.
Explanation:
A Scatter plot is one of the visualization tools which is used to show or represent how much a single variable is affected by the other or what are the effects they have on one another. This visualization tool uses the position of dots on a graph to represent the values of variables.
Scatter plot helps in the show the relation or correlation of variables like temperature and radiation as they affect one other, if the dots are closer it means they have more correlation and vice versa.
Thus, the correct answer is - scatter plot.
Answer:
The scatter plot with the line of best fit (figure 4) is the most helpful in showing the reader the relationship between the two variables. It shows how the values relate to each other and also shows an approximation of that relation.

One of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that, when placed in an aqueous solution, dissociates into a bicarbonate ion (HCO3-) and a hydrogen ion (H+), as noted below.
Answer:
Yes, carbonic acid is the part of blood buffer system.
Explanation:
Carbonic acid is a part of blood buffer system which helps in regulating of pH of the blood. Hydronium ion is responsible for the increase in acidity of the blood. The carbonic acid dissociates into bicarbonate and hydrogen ion, this bicarbonate ions react with the hydronium ion and prevent the pH of the blood from decreasing so we can say that carbonic acid is an essential part of blood buffer system.

In garden pea plants, purple flowers (P) are dominant to white flowers (p), and full pod shape (F) is dominant to constricted pod shape (f). If two heterozygous plants (PpFf) are crossed, what are the potential genotypes and phenotypes that can be expected in the offspring? What is the genotype of the parents? _________________ X ____________________ What are the gametes for each p
Answer:
The phenotypes are as follows
Purple, full- 9
Purple, constricted- 3
White, full- 3
White, constricted- 1
Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.
Explanation:
This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).
In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1
Purple color, full pod- 9
Purple color, constricted pod- 3
White flower, full pod- 3
White flower, constricted pod- 1
