Answer:
Genotypic ratio = 1:2:1
Phenotypic ratio = 3 tongue rollers : 1 non-tongue roller
Explanation:
This question involves a gene coding for the ability to roll the tongue or not in humans. The allele for tongue rolling (R) is dominant over the allele for non-tongue rolling (r).
According to this question, two individuals that are heterozygous for tongue rolling mate i.e. Rr × Rr. The proportion of offsprings that will be likely produced from this cross will be: RR, Rr, Rr, and rr.
- Offsprings with RR, Rr, Rr are tongue rollers
- Offsprings with 'rr' are non-tongue rollers.
Hence, the predicted genotypic and phenotypic ratio are as follows:
Genotypic ratio = 1 RR :2Rr :1rr
Phenotypic ratio = 3 tongue rollers : 1 non-tongue roller

how does a tape worm feed
Answers
Answer:
The tapeworm feeds off the food that the host is digesting.
Explanation:
Tapeworms get into the body when a person eats or drinks something that's infected with a worm or its eggs. Once inside the body, the tapeworm head attaches to the inner wall of the intestines.
Answer:
Tapeworms do not have a digestive tract. Instead, they absorb their nutrients from the gut contents of the host directly through their outside surface, tegument. New proglottids are constantly formed in the neck of the worm and along the length of the tapeworm they mature.

Which of the following was not advocated by the Black Panthers?
a
nonviolence techniques to achieve goals
b
the Black Power movement
c
black nationalism movements
d
community development efforts
Answers
Answer:
A.
Explanation:
The Black Panther Party was a political party formed by Huey P. Newton and Bobby Seale in 1966 in Oakland, California. The party was formed to protect the black community from police brutality. The operations advocated by the Black Panther Party were the Black Power Movement, the black nationalism movement, development efforts for the black community, and violent ways to achieve their goals.
Therefore, the way not adopted by the Black Panthers Party is option A, nonviolent ways to achieve their goals. In reality, Huey P. Newton was convicted of manslaughter for killing a police officer and was sentenced to 15 years imprisonment. Thus option A is correct.
why do you think diversity is important for the survival of a species?
Answers
Answer:
Genetic diversity refers to the amount of genetic variation within a species. Diversity is important for species survival as it provides a way for populations to adapt to changing environments with more variation. More individuals within a population will possess allele variations that are suited to the environment and they will survive more effectively.

A strand of mRNA containing the following repeating sequence: AAGAAGAAGAAG. This sequence of mRNA codes for?
Answers
Answer:
Lysine- Lysine- Lysine- Lysine
Explanation:
This question is describing the process of translation, which is the process by which a mRNA sequence is used as template to produce an amino acid sequence. In the translation process, the mRNA sequence is read in a group of three nucleotide bases called CODONS. Each codon specifies an amino acid.
According to this question in which the following mRNA sequence is given; AAG-AAG-AAG-AAG, one would notice that each codon (AAG) in the sequence is the same and hence codes for only LYSINE amino acid using the genetic code. The amino sequence will read thus: Lysine- Lysine- Lysine- Lysine
Compared to a rounded particle with low density, a HIGH density,
rounded particle of the same size will sink through water
•more slowly
•at the same rate
•more rapidly
Answers
Answer:
more rapidly
Explanation:
Density of a substance refers to the mass of that substance in relation to one unit of its volume. The density of a substance is the basis of whether such substance will float or sink in a liquid. This means that if the density of an object is higher than that of a liquid medium e.g water, the object will SINK while if the density of the object is lower in relation to the liquid medium, the object will FLOAT.
According to this question involving a rounded particle. If the rounded particle is of low density than water, it will float. However, if the rounded particle of the same size is of HIGH density than water, it will SINK MORE RAPIDLY.

Answers
Answer:
The female and male sex cells or gametes are known as eggs and sperm. These cells are formed inside the sex glands and are destined to unite during the fertilization process in order to carry out reproduction in humans.
the male sexual cell is the spermatozoa, they are mobile and can move using their flagellum. Sperm remain alive for 2 or 3 days in the female genitalia. THESE CELLS ORIGINATE INSIDE THE TESTICLES.
Ovules are large, spherical and immobile cells and generally a single egg matures every 28 days, unlike sperm that are generated in large numbers.

Hi, I can help you!
Explanation:
There are more than 3,000 species of snakes on the planet and they’re found everywhere except in Antarctica, Iceland, Ireland, Greenland, and New Zealand. About 600 species are venomous, and only about 200—seven percent—are able to kill or significantly wound a human. Snake vision varies greatly between species. Some have keen eyesight and others are only able to distinguish light from dark, but the important trend is that a snake's visual perception is adequate enough to track movements. A young snake that is still growing may shed its skin up to four times a year, but an older snake may shed only once or twice a year.Snake venoms are complex mixtures of proteins, and are stored in venom glands at the back of the head.[

The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
