Compared to freshwater fishes, marine fishes: drink seawater and produce a large volume of urine. do not drink seawater in an effort to conserve as much water as possible. produce a large volume of dilute urine in an effort to rid their bodies of excess water. tend to gain water by osmosis since their internal salt concentration is higher than that of seawater. tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.
Answer:
The correct answer is - tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.
Explanation:
In freshwater fishes, the body of fishes has a higher salt concentration inside their body than the surrounding water, water enters through the osmosis process. Without any active regulation of this process, fishes would swell and get bigger and bigger. They have specialized cells called chloride cells in gills to take ions from water as they do not have kidneys.
In contrast, the marine fishes have a lower salt concentration in their body than surrounding water of sea or ocean and they lose water continuously and to compensate for this they need to drink water regularly.

Compare the concentration of connective tissue cells found in bone with the concentration of those found in blood.
Answer: CONNECTIVE TISSUE is the most abundant tissue in the body which are widely separated from each other and intercellular substance (matrix) is present in considerably larger amounts. The principal cell of connective tissue are fibroblasts which makes fibres found in almost all connectiv tissues. Some are solid and strong (bone), while others are fluid and flexible( blood).
Explanation:
Connective tissues usually contain fibres present in the matrix which may be of semisolid jelly-like consistency or dense and rigid, depending upon the position and function of the tissue. There are three main types of connective tissue which include:
--> Loose connective tissue
--> Dense connective tissue and
--> specialised connective tissue.
The bone and the blood are considered to be an example of specialised connective tissue. This is so because they both contain a number of different tissues with specialized cells and unique ground substances.
The BONE consists of osteoblasts, osteocytes, and osteoclasts. It is considered to be a specialised connective tissue because the bone cells are surrounded by a matrix of collagen fibres strengthened by inorganic salts, especially calcium and phosphate.
The BLOOD consists of red blood cells, white blood cells, platelets. It is considered to be a specialised connective tissue because the blood cells are surrounded by fluid matrix known as plasma and connecta with other cells through its transport functions.
In COMPARING the concentration of connective tissue cells or bone and blood, the connective tissue cells of bone comsist of fibre and collagen which makes it dense and rigid while the connective tissue cells of blood does not contain any fibre, therefore it's flexible.

Evolution
What is the final result of genetic drift in populations of
Answer: Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation, or rise to 100% frequency, of other alleles.Once it begins, genetic drift will continue until the involved allele is either lost by a population or is the only allele present at a particular gene locus within a population. ... Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool.
Explanation:
Answer:
decrease the genetic diversity of a population.
Explanation:
Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time.
Genetic drift can cause a new population to be genetically distinct from its original population, which has led to the hypothesis that genetic drift plays a role in the evolution of new species.
Complete the complementary strand of DNA, using the same symbols for phosphates (circles), sugars (pentagons), and bases. Mark the 5' and 3' direction of the strands,
Drag the appropriate labels to their respective targets. Terms can be used once, more than once, or not at all
About the question:
You will find the completed strand in the attached files
Answer and Explanation:
First, we need to recognize each strand, the original one and the complementary one. We can recognize the original strand because bases are already given. So,
The original strand is the one at the left,The complementary strand is the one at the right.Now we need to recognize and pair the bases. Names are written with their letters.
Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.
In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.
Once we drag the base labels to their targets, we need to recognize each of the strain extremes.
One of the extremes has a phosphate group, which is named 5´. The other extreme has a hydroxyl OH named 3´. Both of them are readen in the 5´to 3´ direction. The polymerase enzyme reads the original strand in 5´ to 3´ mode, and the molecule lecture goes from 3´to 5´.
So, by looking at the labels, we will recognize the phosphate extreme and the hydroxyl one. We will place in the superior extreme of the original strain the phosphate group 5´ and in the other extreme the OH 3´. These positions will give us the direction reflected by the arrow. The complementary strand will have the same extreme labels but in opposite places. So first we will place the OH 3´ label in the superior extreme, and the phosphate 5´label in the inferior extreme, defining the direction reflected by the arrow.
With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring It is estimated by a wide body of scientists that in recent decades we have begun another mass extinction event on Earth. Amphibians in particular have been in decline, sometimes due to climate change, and they therefore provide a possible early sign of dramatic biodiversity change to come. With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring may have no effect at all, be beneficial, or be harmful. will primarily be harmful. will only speed the decline and extinction of the species. could either be beneficial or harmful.
Answer:
be beneficial.
Explanation:
Mutations of DNA sequences of the frog genome that are inherited by offspring will be beneficial for the frog because this mutation in the genetic makeup of frog provides resistance in this new environmental conditions. This mutation occurs due to the exposure of cell's DNA to the environmental factor which gives benefit to the organisms to survive different condition which can't tolerate by their parents so this mutation is beneficial for that offspring of frog.

Which part of the female reproductive system is highlighted below?
A. Fallopian tube
B. Ovary
C. Uterus
D. Cervix
Answer:
C. Uterus
Explanation:
Uterus is the female reproductive system.
What is Female reproductive system?The female reproductive system serves a number of purposes. It aids in sexual reproduction in addition to enabling sexual activity.
You make eggs using your ovaries. During ovulation, these eggs are subsequently moved to your fallopian tube where sperm fertilization may take place. The fertilized egg is then transferred to your uterus, where the lining of the uterus has expanded due to the typical hormones produced during your menstrual cycle, also known as your reproductive cycle.
The fertilized egg can implant into the thicker uterine lining once it's within your uterus and continue to grow there. Your menstrual period causes the uterine lining to shed if implantation doesn't occur.
Therefore, Uterus is the female reproductive system.

The most likely reason(s) a metastatic tumor cell might lose its connection to the basal lamina would be: a change in the integrin proteins from the cell's surface. a change in the cadherin proteins on the cell surface. a change in connexins disrupting gap junctions. All of these choices are correct.
Answer:
A change in the integrin proteins from the cell's surface.
Explanation:
Integrin proteins' principal function is to attach the cell to the basal lamina. Also, they transmit signals from the extracellular matrix to the interior of the cell. A change in the integrin could result in loss of connection between the mutated cell and the basal lamina.
Cadherin proteins connect one cell to another. A change in these proteins will not result in the loss of connection between the metastatic tumor cell and its extracellular matrix. It most likely will affect the communication and adhesion of cells.
A change in connexins will disrupt the communication between cells but not the connection to the lamina basal. Connexins are transmembrane proteins that connect one cell to another with gap junctions that allow the passage of different components from cell to cell.
