Answer:
Related organisms always appear identical in embryonic stages.
Explanation:
Embryos of organisms that have a closer genetic relationship to one another tend to look similar for a longer period of time since they share a more recent common ancestor. Thus, embryology is frequently used as evidence of the theory of evolution and the radiation of species from a common ancestor.

Answer:
Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Some examples include height, skin color, eye color and weight.
- In polygenic inheritance the "dominant" capital genes are additive, each capital gene adding one unit of color to the genotype.
What results from meiosis of a diploid cell?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell
Explanation:
Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. ... The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

Extracellular signal molecules that are hydrophilic must bind to a cell-surface receptor in order to signal a target cell to change its behavior. These are examples of hydrophilic hormones in animals: A. tyrosine-derived epinephrin and norepinephrin B. insulin and glucagon C. serotonin and melatonin (tryptophan-derived mammalian neurotransmitters D. All of the above E. None of the above
Answer:
The correct answer is - D. all of the above.
Explanation:
Hydrophilic hormones are the hormones that can not pass through the cell membrane as they are poorly lipid-soluble and cannot pass through cell membranes and bind the receptors present on the surface of the membrane.
Insulin and glucagon are peptide hormones that bind to a receptor in the target cell's membrane surface. Norepinephrine and epinephrine are catecholamines that are hydrophilic in nature. Seratonin and Melatonin are also bound on the surface receptor due to their hydrophilic nature.

Small, nonpolar hydrophobic molecules such as fatty acids
a. pass readily through a
membrane's lipid bilayer
b. diffuse very slowly through the lipid bilayer
c require special channels to enter a cell
d. are actively transported across cell membranes
c. must enter the cell via endocytosis
Answer:
a. pass readily through a membrane's lipid bilayer
Explanation:
Small, nonpolar hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer.
Small, nonpolar hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer. Therefore, the correct option is option A.
The hydrophilic (water-loving) heads of the two layers of phospholipids in the lipid bilayer face outward towards the aquatic surroundings, while the hydrophobic (water-hating) tails point inward towards one another. The hydrophobic tails of phospholipids share characteristics with nonpolar hydrophobic compounds like fatty acids. These tiny molecules can easily dissolve in the hydrophobic area of the lipid bilayer because of their hydrophobic nature.
Therefore, the correct option is option A.

how do floods affect abiotic and biotic factors
Water is important to every organism. A great portion of chemical reactions that organisms use take place in water, so without water, organisms would not be able to metabolize anything. ... Primary consumers (herbivores) would suffer twofold as their prey (the plants) die and their water source disappeared.

Answer:
X: positive

Explanation:
The charges of the objects are:
OX: positive

The concept of electric field lines is a way to visualize the electric field around a charged object or group of objects. Electric field lines point in the direction of the electric field at each point, and the density of the lines corresponds to the strength of the electric field.
By following the direction of the field lines, we can make an inference about the relative charge of the objects. For example, field lines that originate from a positive charge will terminate on a negative charge, while field lines that originate from a negative charge will terminate on a positive charge.
Therefore, based on the field lines, we can determine that:
Option 1 is incorrect, as the field lines terminate on a negative charge.
Option 2 is incorrect, as the field lines originate from a negative charge.
Option 3 is incorrect, as the field lines originate from a negative charge and terminate on a negative charge.
Option 4 is correct, as the field lines terminate on a positive charge.

Question 7
In prokaryotic cells, the ribosomes:
O A. synthesize proteins
O B. synthesize nucleic acids
O C. synthesize sugars
O D. synthesize fatty acid
Answer:
[tex]\boxed {\boxed {\sf A. \ Synthesize \ proteins}}[/tex]
Explanation:
The ribosomes are small organelles made of RNA and proteins. Its function is the same in both prokaryotic and eukrayotic cells: protein synthesis.
The process begins in the nucleus. The DNA and genetic information is housed here. Certain sections are transcribed and copied to make messenger mRNAs that can fit through the nucleus and pores to travel out to the ribosomes.
The ribosomes use the mRNA in a process called translation. They match each set of 3 nucleotides (a codon) in the mRNA to 1of 20 different amino acids. A special sequence of amino acids forms, the molecule folds, and a protein is formed.
So, a ribosome is the main site for protein synthesis and the correct choice is A.

Answer: Government and law
Explanation:
In many large mammal populations, highways can be barriers to movement - individuals rarely cross them. One solution to this problem has been to install overhead bridges for wildlife to safely cross. The goal is to increase gene flow between the populations on either side of the highway. Which of the following would you expect to see if the bridge is successful in its goal?
a) The two populations would have different mutation rates
b) We would see fewer heterozygotes in both populations
c) Higher levels of drift would occur after the bridge is installed
d) The two populations would become more genetically similar
e) Both populations would decrease in size
Answer: c. Higher levels of drift would occur after the bridge is installed
Explanation:
Based on the information given in the question, if the bridge is successful in its goal and overhead bridges are installed for wildlife to safely cross, then there'll be higher levels of drift after the bridge is installed.
Since the highways are barriers to the movement of the wildlife, overheard bridges will bring about movement on the other side of the highway and this will result in and increase in drift between both parts of the highway. This will also help in the increase of gene flow between the populations.
Therefore, the correct option is C.

You went running on a hot day. After your run, you sit down and feel very warm. How is homeostasis reacting?
Answer:
When you run, your muscles use energy and contract. This contraction and use of muscle fibers produces heat, lactic acid, and carbon dioxide. Your body will attempt to correct homeostasis by sweating to cool down your body (When the water in your sweat evaporates, it takes some heat energy with it), you breath harder to get rid of the excess carbon dioxide, and your blood attempts to clear the lactic out of your muscles.
Elephants live grouped in herds. This is why it is so difficult for a lone elephant living at a circus or exhibit. What type of population distribution do we call animals that live in herds, schools or other groups?
A
random
B
uniform
C
clumped
D
density cluster
Answer:
clumped
Explanation:
Uniform dispersion is observed in plant species that inhibit the growth of nearby individuals. Random dispersion occurs with dandelion and other plants that have wind-dispersed seeds that germinate wherever they happen to fall in a favorable environment. Clumped dispersion is seen in plants that drop their seeds straight to the ground, such as oak trees, or animals that live in groups, such as schools of fish or herds of elephants.
