Answer:
Smooth hair is dominant in horses, and curly hair is recessive: Ss
Black hair is dominant, and chestnut hair is recessive: Bb
Explanation:
Dominant traits are the strong traits pass in the next generation and an individual show dominant traits while recessive traits are the weak alleles that are less likely to pass in the next generation.
It is given:
Smooth hair = S
Curly hair = s
Black = B
Chestnut = b
So according to this, horses with Smooth hair as dominant trait and horses with curly hair as a recessive trait will be referred as Ss and Black hair is dominant, and chestnut hair is recessive will be referred as Bb.
Answer:
Smooth hair is dominant in horses, and curly hair is recessive. Black hair is dominant, and chestnut hair is recessive. If S denotes smooth and s denotes curly, B denotes black and b denotes chestnut, classify the alleles according to their types.

why was an Archea considered as a prokaryote
Answer:
Archaea is prokaryotic because it doesn't have a nucleus, nor any membrane-bound organelles. The reason why Archaea is different from Bacteria is it is more prominent, most of them are extremophiles.
because they are composed of cell which doesn't have nucleus and other some cell organelles and also considered as incomplte cell.
What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2? a = 5, b = 4, c = 2 a = 5, b = –4, c = –2 a = –4, b = 5, c = –2 a = 4, b = –5, c = –2
Hey there! :)
Answer:
The 3rd choice. a = -4, b = 5, c = -2.
Explanation:
Rearrange the quadratic equation given into the form 0 = ax² + bx + c:
0 = 5x - 4x² - 2 --> 0 = -4x² + 5x - 2
The corresponding coefficients for the a, b and c values are:
a = -4
b = 5
c = -2.
The given quadratic equation must be first rearranged in the form ax2- bx-c. From this, we can find the values of a= -4, b= 5, and c= -2
How can a quadratic equation be defined?Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations. The general form of the quadratic equation is ax² + bx + c = 0.
Quadratic equations are commonly used in situations where two things are multiplied together and they both depend on the same variable. For example, while working with the area, if both dimensions are represented in terms of the same variable, you use a quadratic equation.
Throwing a ball, shooting a cannon, diving from a platform, and hitting a golf ball are all examples of situations that can be modeled by quadratic functions.

n which environment would mineral formation caused by high pressures and high temperatures most likely occur?
Answer:
when the flood or landslide flows theremnants of plants and animals are taken to the sea and ocean then due to high pressure and temperature they forms fossils in sedimentary rocks and due to the anaerobic condition under the fosdils gets decayed and it forms the layer of mineral. so we can say thatminerals are formed in anaerobic condition under sedimentary rocks.
A student recorded the height of each student in the school. She then made a bar graph of her results. She observed that
the results form a bell-shaped curve. The student could use her graph as evidence to support which argument?
Height is affected by multiple pairs of genes on different chromosomes.
The alleles for tall height and short height are codominant.
The allele for being tall is dominant to the allele for shorter heights.
There are three alleles for height that demonstrate incomplete dominance.
Answer:
Height is affected by multiple pairs of genes on different chromosomes.
Explanation:
The height is a quantitative trait, it is a phenotypic feature that presents a continuous range of variation in the population. The cumulative effects of many genes and the environment produce a normal distribution bell-shaped curve when they are drawn, this being a characteristic of quantitative genetic traits. Examples of quantitative traits include, among others, height, metabolic rate and weight.
The student could use their graph as evidence to support the argument that "The alleles for tall stature and short stature are codominant."
What is a Codominant gene?Codominant: Autosomal codominant inheritance is the condition in which the heterozygote has the characteristics determined by both alleles (dominant and recessive).
What is allele?Allele genes are those that occupy the same locus on homlogous chromosomes and are involved in determining the same character.
With this information, we can conclude that the genes alleles of the students in this class are codominant.

Construct at least two possible hypotheses for the student’s experiment
Answer:
OFFICIAL SAMPLE ANSWER (Do not copy verbatim):
Hypothesis 1: The natural nutrients in compost will cause the tomato plants to grow at a faster rate than they grow when given artificial fertilizer.
Hypothesis 2: The artificial fertilizer is formulated specifically for tomato plants, so it will cause the plants to grow at a faster rate than they grow when given compost.
Explanation:
If questioned for situation below.....
"Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.
"
1. compost pits and manure use, bio gas can be produced
2. using natural compost replenishes the soil fertility in the long run unlike the chemical fertilizers are two possible hypotheses for the student’s experiment
What are the basics of experiment ?The basics of experiment is to test the hypothesis what we set previously and it is a foundation of the scientific method, types of experiments include controlled experiments, field experiments, and natural experiments.
The key steps taken in scientific method are observations, ask a question, making of hypothesis, design and conduct experiment, result, accept or reject or repeat the hypothesis from result.
The most important parameter taken in an experimental set up is variable which can be dependent, independent and controlled variables where the independent variable is something which can not influenced by other factor.
A dependent variable can be changed by the influence of independent variable and Control variable can be used to check bias of experiment.

A population of birds lives on a small island. Another population of the same species lives on the mainland. The distance between the island and the mainland is too great for birds to fly back and forth. Recently, a series of sandbars and tiny islands have formed between the island and the mainland?
Answer:
Explanation:
Based on this information it can be said that this formation between the islands and the mainlands will most likely cause an increase in gene flow between the bird populations. Since the islands and the mainland are now connected birds from both these two different habitats will begin mating and producing progeny, thus causing gene flow to increase between these species.
Answer:
An increase in gene flow between the birds population.

Craig Mellow investigated RNA interference by injecting antisense and double-stranded RNAs into C. elegans. If the antisense and double-stranded RNAs were very similar, but not identical, to C. elegans mex-3, what would be the results of their experiment
Answer:
It is required that the seed region of the processed dsRNA molecule bind to the mRNA of mex-3 in order to inhibit its translation
Explanation:
Double-stranded RNAs are small interfering non-coding RNAs (about 20 nucleotides in length) that, after processing, can bind by complementary base pairing to RNAs and thus inhibit protein translation by a mechanism referred to as 'RNA interference' (RNAi). The base pairing is not always perfect; however, the guide strands of dsRNAs can conserve their ability to inhibit the translation if the complementarity is enough good to match target RNA sequences. The critical region in the dsRNA that is required to bind target RNAs is known as seed region, and consists of 6 to 8 nucleotides in length.

It’s your first day shadowing a detective, and already it’s been interesting…if you can call the murder of a young woman interesting. You’ve been trying to detach yourself by reading the file, but you have interviews later this morning and you’re nervous. Going back to the file, you jot down some notes on what you know so far.
Melissa was a 35-year-old nurse-midwife with over ten years’ experience delivering babies both in hospitals, as well as in homes when risk for complications were low. She was healthy; her only medical condition was an allergy to bee stings. The body was discovered by her boyfriend when he came over for a planned dinner. The dinner – spaghetti – was laid out, but no cooking had begun. There was also a plate of cupcakes, with a bite out of only one of them. The boyfriend said Meleea had not mentioned feeling unwell when they spoke earlier in the day. She was, however, tired, and understandably upset about a long birth she had assisted with where a mother had died in childbirth.
The medical examiner did not have results yet, so you sketch out some questions you have for the interviewees.
1. Who would you interview, and what would you ask?
2. Do you have any hypotheses about what happened to Meleea? Write at least one or two possibilities.
1. I would interview the boyfriend and family members of the mother who died in childbirth. I would ask where they were at time time of death and if they have an alibi.
2. There could have been something put in the cupcakes, since only one bite was taken from a single one.

Based on what you know of bone features, what do you think this canal is for? Why would we need a hollow space in this area of this bone?
Answer:
The mandibular canal, also referred to as the Inferior Alveolar Canal (IAC), sits within the mandible. It serves the purpose of housing the inferior alveolar nerve which is responsible for supplying sensation to the lower teeth.
This canal also houses the inferior alveolar vein - a dental vein whose function is to (with the assistance of the posterior alveolar artery) drain blood from the lower teeth and jaw.

difference between plant and animal cyanide resistance respiration.
Answer:
The cyanide resistant respiration differs in plants as oxidation of reduced coenzyme continues even in the presence of cyanides.
Explanation:
The mitochondrial is the electrons through which the animals and plants perform the aerobic exercise and is blocked by the release of the cyanides that stops the activity and is known as cyanide sensitive respiration Plant mitochondria is different from the animal as they both have different oxidase system pathways. Cyanide resistant is responsible for the climacteric in fruits and for the generate heat in thermogenic tissues.1.
