2. A certain recessive, lethal gene is carried on the X chromosome. (Lethal genes are those that result in death.) A man marries a woman who is hybrid for this gene. What sex ratio would be expected among the living children of this couple?
%Male
%Female
PLEASE CAN ANYONE HELP ME THIS IS MY THIRD TIME POSTING!
NO LINKS PLEASE THEY ARE TIRING
Answer:
The correct answer is : male : female = 1:2
Male percent = 33.33%
female percent = 66.66%
Explanation:
In this question, it is given that a lethal gene is carried by X chromosome which is recessive which means will cause death if both copies are recessive for this gene.
The cross between normal man and hybrid or heterozygous women
The gametes: XH and Y from man and XH and Xh from women where Xh is recessive letheal allele.
The cross:
XH Y
XH XHXH XHY
normal female Normal male
Xh XHXh XhY
Carrier female dead male
This explains that out of three offspring two will be females and one male. Thus the percentage will be:
Male : 1*100/3 = 33.33%
Female : 2*100/3 = 66.66%

Based on the information given above, which of the following models best represents the relationship between zooplankton , minnows, and largemouth bass in a freshwater ecosystem?
Chose the correct image to answer the question above. NEED THIS FAST
Answer:
Option C: Minnows have a direct negative effect (⇒(-)) on the population size of zooplankton. Basses have a negative effect (⇒(-)) on the population size of minnows. Basses have an indirect positive (---> (+)) effect on zooplankton.
Explanation:
In the trophic web occurs a process of energy transference through different organisms that places at different levels. Each level feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer. The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
If any of the links change their population size (increasing it or decreasing it), it affects the superior links and the immediately anterior link.
In the exposed example, zooplankton, minnows, and basses are continuously interacting.
Minnow →(-) ZooplanktonMinnows feed on zooplankton. So they affect direct and negatively the invertebrate population. The more minnows there are, the more zooplankton they eat. So, as long as the minnows population keeps growing, the zooplankton population will be more affected because they will not have enough time to reproduce and recover from predation.
Bass →(-) Minnows
Bass feed on minnows, so they also affect direct and negatively the fish population. And the more the bass population grows in size, the more affected the minnows will be because many more basses will be eating them.
Bass ---->(+) Zooplankton
On the other hand, by negatively affecting the minnows population, basses will be indirectly and positively influencing the zooplankton population. This fact is because the more minnows basses eat, the fewer fishes there will be to prey on zooplankton. So the invertebrate will have enough time to recover its population size. The predation pressure acting on zooplankton will decrease thanks to the action of basses preying on minnows.
Here there is a natural equilibrium between the three species. It is a representation of typical cycle predator-prey.
Minnows prey on zooplankton. Minnows population grows, and the zooplankton population decreases.As the minnow population grows, there is more available food for basses, who eat more minnows. As the bass population increases, the minnows population decreases in size. And as there are fewer minnows, the zooplankton population will increase. If minnows decrease in number, basses will decrease in number too. Minnows will not be severely affected by basses, so their population increases again. As zooplankton also increased, there will be more available food for minnows that will keep reproducing. And the more minnows there are, the more available food for basses there will be. And basses population will increase again. So you can see that zooplankton is indirectly and positively affecting the basses population too (not shown in images).how can identifying birds in your area help scientists

What is created by a large pressure difference in air fronts?
A. Density
B. Dewpoint
C. Wind
D. Isobars
Answer:
A. density.
Explanation:
At a front, the two air masses have different densities,
based on temperature, and do not easily mix. One air mass is lifted above the
other, creating a low pressure zone. If the lifted air is moist, there will be
condensation and precipitation. Winds are common at a front.

Explanation:
Shotgun sequencing is a method used to determine the nucleotide sequence of entire chromosomes/genomes. This sequencing method consists of obtaining random DNA fragments which are subsequently classified by bioinformatic tools that ordering them according to overlapping sequences called contigs. In the whole-genome shotgun (WGS) technique, the entire genome of an organism is sequenced, being the critical factor the depth of sequencing, which refers to the quality of the sequencing reads (e.g., a depth of 20X indicates that the genome is sequenced 20 times by a sequencing machine). For the human genome, WGS became available after the completion of the Human Genome Project (HGP), which enabled the generation of a reference sequence for the whole human genome. The steps of the WGS technique are the following:
1. Preparation of isolated chromosomes
2. The DNA is sheared into small fragments
3. The DNA fragments of about 1 kilobase (1000 base pairs) are incorporated into plasmids which are cloned to render pure samples of each DNA fragment
4. The plasmid clones are sequenced by sequencing machines
5. Bioinformatic tools finally are used to link DNA fragments by their overlapping ends

Question 6 (1 point) Which part of the renal tubule has a membrane that only filters out the very largest of molecules?
loop of Henle
distal convoluted tube
proximal convoluted tube
renal capsule
Proximal convoluted tube I thinkkkkkkk
The part of the renal tubule has a membrane that only filters out the very largest of molecules is Proximal Convoluted tube. Thus, option C is correct.
What is the function of Proximal Convoluted tube?Proximal Convoluted tube has been responsible for the reabsorption of nutrients as well as the substances that the body needs. Loop of Henle is known as the part which is a thin-lobed structure that controls the concentration of the urine.
Distal convoluted tubule performs a very important as it regulates sodium, potassium and pH. Collection duct function it regulates water and sodium reabsorption.
Nitrogenous wastes has been excreted in the urine encompass urea, creatinine, ammonia, and uric acid.Nephrons start withinside the cortex; the tubules dip right all the way down to the medulla, then go back to the cortex earlier than draining into the accumulating duct.
Thus, option C is correct.

On the planet Feline, there are only cats. For one particular phenotype, Myles, there are two manifestations: either the cats like jazz music (the wild type phenotype) or they do not (the mutant phenotype). Under the assumption this phenotype is determined by a single gene with two alleles, and given that a mating of two wild-type cats produces the following number of offspring: Female, wild-type: 341; Male, wild-type: 369; Female, Myles: 121; Male, Myles: 123. The mode of inheritance most consistent with these data is:________
A. Autosomal dominant.
B. Two-locus inheritance.
C. Sex-linked recessive.
D. Autosomal recessive.
E. Two-locus dominant.
Answer:
D. Autosomal recessive.
Explanation:
Available data:
One diallelic gene codes for the phenotype MylesOne allele expresses the wild type phenotype → like jazz musicThe other allele expresses the mutated phenotype → don´t like jazzCross: Between two wild catsF1) Female, wild-type: 341; Male, wild-type: 369; Female, Myles: 121; Male, Myles: 123Autosomal recessive inheritance characterizes because the mutated gene locates in one of the 22 non-sexual, somatic chromosomes. To express the phenotype, an individual must carry two copies of the mutated gene. For this reason, the recessive allele must be present in both the male/father and the female/mother.
In the exposed example, the numbers among the progeny are 341:369:121:123. These values approximate a phenotypic ratio 3:1 for females, and for males. This ratio suggests that the cross was performed between two heterozygous individuals.
Let us name the alleles M and m, dominant and recessive respectively. The cross would be like follows
Cross: wild-type male x wild-type female
Parentals) Mm XY x MmXX
Gametes) MX, MY, mX, mY MX, MX, mX, mX
Punnett Square) MX MX mX mX
MX MMXX MMXX MmXX MmXX
mX MmXX MmXX mmXX mmXX
MY MMXY MMXY MmXY MmXY
mY MmXY MmXY mmXY mmXY
F1) Whole progeny
12/16 = 3/4 = 75% Wild-type cats → MMXX + MmXX + MMXY + MmXY4/16 = 1/4 = 25% Mutated cats → mmXX + mmXYFemales
6/8 = 3/4 = 75% Wild-type cats → MMXX + MmXX 2/8 = 1/4 = 25% Mutated cats → mmXXMales
6/8 = 3/4 = 75% Wild-type cats → MMXY + MmXY2/8 = 1/4 = 25% Mutated cats → mmXY
Why does the the right testicle hang lower than the left?? PLease help i will be thank (Sorry english second language if your wondering why my grammar might be a little off. I formally apologize for any confusion the weird spelling. )
it is entirely normal for one testicle to be bigger than the other. Many people find that the right testicle is slightly larger and the left hangs lower. A difference in size is usually nothing to worry about, though it can occasionally indicate a problem.
This is perfectly normal and nothing to worry about. Either side may be slightly larger or hang lower. But be sure to tell a parent (who will let your doctor know) if you have any pain, swelling, or lumps in your testicles.
When a vein in a testicle becomes enlarged, it's called a varicocele. Varicoceles affect up to 15 percent of males. Like varicose veins in your legs, varicoceles may appear bulgy under the skin of your scrotum. They tend to form in the left testicle because the vein on the left side hangs lower.
