The gallbladder provides ________ that aid(s) in transport of lipids across the intestinal membrane.
The gall bladder provides bile salt.
The gall bladder is a small pear-shaped organ that is located at the abdomen inferior to the liver.
This organ stores and releases the bile salt produced from the liver.
The bile salt is released through the bile duct into the duodenum of the small intestine.
The bile salt is use to emulsify fat thereby aiding it's transport across the intestinal membrane.
Therefore, the gall bladder provides bile salt that aids in transport of lipids across the intestinal membrane.

Hemophilia is an X-linked trait caused by the allele h. About 1 in 10,000 males (0.0001) has hemophilia. The frequency of the h allele in males is therefore
.
Answer : 0.0001
Explanation:
Since males only have 1 X chromosome, the number of males with h alleles should be equal to number of males with Haemophilia and therefore the frequency of males with Haemophilia must be equal to the frequency of h alleles on X chromosome.

A disputed paternity case! Hermione’s new baby has a blood type of O. Her blood type is B and Ron Weasley is A. Harry Potter (blood type AB) insists he is the child’s father. CAN THIS BE TRUE???!
Answer:
No becuase one of the parents needs to have type O
Explanation:
No, this cant be true because in order for a child to have O blood type parents must have a recessive allele "[tex]i[/tex]".
What type of alleles are blood types?An allele is a particular form of genetic information that can be found in our DNA at a particular spot on a certain chromosome. This form of genetic information is known as an allele.
Codominant alleles in humans are responsible for determining blood types. There are three distinct alleles, and they are denoted by the letters IA, IB, and i. The IA and IB alleles both have co-dominant inheritance, but the i allele has a recessive inheritance pattern. Type A, type B, type AB, and type O are the four different human phenotypes that are possible for the blood group.
Therefore, in order for a child to have O blood type parents must have a recessive allele "[tex]i[/tex]"

Variation in offspring is important in maintaining genetic diversity within a population . Which of the answer choices indicates a mechanism of introducing genetic variation in a population? Select all that apply.
A crossing over during meiosis B ) fertilization of an egg by a sperm
C) independent assortment during meiosis
D) mitosis producing two new daughter cells
E) binary fission resulting in two bacterial daughter cells
Answer:
A B and C
Explanation:
Crossing over breaks, exchanges and rejoins chromosomes at corresponding points so introduces genetic variation. Because of crossing over offspring has characters of both parents.
Also independent assortment means that during separation of the chromosomes in anaphase, any chromosome can pair up with another. So for example if we have one parent plant with yellow and wrinkled seeds and other one with green and round seeds, then the gene responsible for round seed can pair up with either of the genes responsible for yellow seeds or green seeds. Hence the characters of offspring differ from the parents, it can have yellow round seeds or yellow wrinkled seeds and so on.
Mitosis will only produce 2 daughter cells which are exactly like their parent cells and are also identical to each other. Binary fission is a form of Asexual reproduction so it does not involve shuffling of genes from 2 parents.
Because of fertilization of egg with a sperm the maternal genes and paternal genes mix together. So it also produces genetic variations.

As wind passes over a mountain, the side over which the wind rises tends to be ____________________ and the side that experiences the downward movement of air tends to be ____________________.
drier; moist and rainy
moist and rainy; drier
rainforest; desert
desert; rainforest
Given what we know about the effects of air currents on mountain ranges we can confirm that the correct option is option B, moist and rainy on one side while being dier on the other.
Mountains are described as having two sides in regards to their relationship with the air currents. The side of the mountain on which the wind rises is known as the windward side, whilst the side on which air descends is known as the leeward side. The windward side is typically in contact with warmer, moist air from the ocean and other bodies of water.
When coming in contact with the mountain, the air is forced to rise and begins to cool, which often leads to rain or snow. The leeward side of the mountain receives the air that has now already lost the majority of its moisture with its pass through the windward side of the mountain. This air also tends to become warmer as it descends, which explains the dry nature of the leeward side of mountains.

Linkage maps and physical maps are NOT the same. A linkage map measures the number of recombination events in a given chromosome fragment.
A linkage map is based on the frequency of recombination events between genes or molecular markers.
This frequency indicates the number of events in which a single chromosomal fragment recombines between two or more genes or molecular markers during meiosis.
Conversely, a physical DNA map indicates the physical locations of genes (molecular markers) and nucleotide (DNA) sequences of interest, which is useful to identify genes by positional cloning.

Your Mother needs to transfer (i.e., encode) a list of 25 vocabulary words from her STM to her LTM. She asks for your help. You suggest that she use elaborative rehearsal and you begin to train her in this technique. What do you ask your Mother to do?
1) you ask her to repeat the words over and over again
2) you ask her to give each word meaning by using each word in a sentence
3) you ask her to break down each word into various "chunks"
4) you ask her to memorize each word and its meaning
*PLEASE ADD EXPLANATION*
The best technique for your mother is that she uses each word in a sentence to give it a meaning, and remember it better (option 2).
Elaborative rehearsal is a common technique used to remember information in a long-term way. Due to this, this technique can be used to move information from short-term memory to long-term memory.
In this technique, the main purpose is to associate the new information with something you already know. In learning new words, this can include:
Associating new words to images.Creating examples of sentences.Associating a new word to a synonym you already know.In this context, the technique that is part of elaborative rehearsal is using the word in a sentence (option 2).

What are some of the posible signals of male quality in widowbirds and what information might they convey? What are the females choosing and why
Male produces signals of bright red, yellow epaulets and long tails.
Males produce bright red and yellow epaulets as well as chevrons on their wings. These bright epaulets attracts the female of this species and helps in the sexual activity of widowbird species.
The males of several widowbird species also grow long tail feathers about half a meter in length. The long tail is favored by sexual selection through female choice of mates. Female prefer long tails red-collared widowbird so we can conclude that male produces signals of bright red, yellow epaulets and long tails.

Which equation shows how matter is transformed and conserved in photosynthesis? In other words, which is the balanced chemical equation for
photosynthesis?
O 602 + 6H2O + Sunlight → CH208 + 6CO2
O 6CO2 + 6H2O + Sunlight → CH,20g + 602
O CH120o + 6CO2 → 602 + 6H20 + Sunlight
son
CH,208 + 602 → 6CO2 + 6H2O + ATP
Answer:
B
Explanation:
The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2
the answer is not exact, but it is the closest to the actual equation
The equation shows how matter is transformed and conserved in photosynthesis is O 6CO2 + 6H2O + Sunlight → CH,20g + 602. Thus, option B is correct.
What is photosynthesis?Photosynthesis can be described as a process which plants use to produce their own food. In this process, carbon dioxide and water get converted into sugar (glucose) and oxygen. Light energy from the sun is needed for this reaction to occur. The excess oxygen produced by this process is released into the atmosphere. The sugar made is used as fuel by the plant.
Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules. Cellular respiration can occur in the presence of oxygen (aerobic) and this combines glucose molecule to form carbon dioxide (CO2) and water (H2O) and release energy for use.
The equation best models cellular respiration is: C6H12O6 + 602 = 6H20 + 6CO2 + Energy (ATP). The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2.
Thus, option B is the correct option.
