Sonographic findings of severe micromelia, decreased or absent ossification of the spine, macrocephaly, and micrognathia describe which one of the following conditions?
a. Achondrogenesis
b. Achondroplasia
c. Osteogenesis imperfecta
d. Diastrophic dysplasia
Answer: Option A.
Achondrogenesis
Explanation:
Sonographic findings of severe micromelia, decreased or absent ossification of the spine, macrocephaly, and micrognathia are conditions of Achondrogenesis because
Achondrogenesis is a genetic disorder that is as a result of mutations in gene SLC26A2 which is responsible for cellular transport proteins that is needed for the growth and development of bones and cartilage. This condition lead to malformation of bones and cartilage and it is characterized by short limbs, small body, narrow chest ,prominent abdomen,underdeveloped lungs,lack of ossification in the spine and pelvis, prominent head, small chin e.t.c.
It is a condition that affects infants.
The major treatment is pallative care in which the doctor have to reduce pain stress of bones and cartilage and also genetic councellling.

Which of the following is the best representation of a solid?
Answer:
its the one that looks like a cube
Explanation:
Glucose molecules from food sources provide energy to the cells of the human body. After a person eats, the level of glucose in their blood increases. If a person's blood glucose level becomes too high, a hormone in the pancreas, known as insulin, is released. Insulin helps move glucose out of the bloodstream. This causes the blood glucose level to decrease and return to equilibrium. The production of insulin is a mechanism that regulates the human body's internal environment and aids in
Answer:
regulating blood sugar levels
Explanation:
The primary function of the insulin hormone is to convert the excess glucose in the blood after a meal and store it for later. Glucose gets converted to glycogen, which is a compact molecule ideal for storage. When the body is need of energy, this glycogen is broken down to make up for the lack of glucose present in the blood.

Answer:
Explanation:
Biology can be referred to as the study of life.
One question that can be asked about the study of life is "if green plants excrete". Since excretion is one of the characteristics of living things, one question that could be intriguing is the possibility of plants performing this process.
This question can only be answered be answered/verified by a scientific experiment because the process cannot be observed/determined with the naked eye.
Compare your observations of micrographs obtained from the optical microscope, the scanning electron microscope, and the transmission electron microscope
Answer:
Transmission electron microscope is the best one due to high magnification power.
Explanation:
Micrographs or photograph obtained from the optical microscope is not very clear because it has the magnification power up to 1000x while the scanning electron microscope has magnification power 30000x which is quiet higher than optical microscope so the micrographs is better than optical microscope and gives more information about the specimen, and the transmission electron microscope has the magnification power up to 500000x which has the highest of magnification so the micrographs obtained from this microscope is the best due to more information about the size and structure of the specimen.

All plants and some algae have a complicated life cycle that includes both a multicellular diploid _______ stage and a multicellular haploid _______ stage. This type of life cycle is called _______.
Answer: sporophyte, gametophyte, alternation of generation
Explanation:
Alternation of generation is a kind of life cycle seen in plants and algae in which the diploid asexual and haploid sexual stages exist. A sporophyte is multicellular and diploid which is an asexual stage. It produces the haploid spores through meiosis. The haploid spores germinate to produce haploid gametophyte. The gametophyte produces gametes by the process of mitosis.
Compare the inputs and outputs of humans and robots in terms of matter and energy.
Answer:A robot is a machine. It is often, or almost always, automatic, which means that it is able to perform activities on its own without the aid of external variables, like humans. It moves in the way that it was originally programmed, or designed to act. These actions are described as ‘intents’ of its own. For example, a robot that is designed to play ping pong will really move like a ping pong player, compared to a robot that is just used for plain surgical operations.
‘Robot’ is also a word that refers to the sum of all the groups of robots, comprised of the physical robots and the virtual robots (as in software). In the case of the latter, these are called bots.
Human beings are also highly social individuals. They survive alongside other people in groups called communities or families. They are capable of forming relationships, and generating complex feelings, or emotions such as love.
1. Humans are organic beings, while robots are not.
2. Humans are far more complex and superior to robots in almost all aspects.
3. Humans are highly social beings compared to robots

What conclusion can be made if a positive test was the result for any of the organic molecules for the water sample? This a question from a assignment that has to do with a lab we did today.
Answer:
Because some effects will occur.
Explanation:
The positive test which was the result for the organic molecules for the water sample showed that there is some change occurs in water sample by adding of organic molecules due to which the results of the test comes positive. If there is no change occurs in the water sample by adding some organic molecules so the results will come negative which means no effect.
if you were 6’6 1/2 tall, about how many meters tall would you be
Answer:
1.99metres
Explanation:
Foot and inches are measurements of heights. A height measurement of 6’6 1/2" means I am 6 foot and 6.5 inches tall.
Firstly, we need to convert the foot and inches measurement to all foot.
Since 1 foot = 12 inches
Then, the 6.5 inches is 6.5/12
= 0.5416foot
We add this to the existing feet measurement, i.e. 6 foot + 0.5416 foot
= 6.5416 foot.
Hence, 6'6.5" means 6.5416'
Now, we convert the foot measurement to metres.
1 foot makes 30.48 cm
Since 100 cm makes 1 m
30.48 cm will be 30.48/100= 0.3048m
Hence, 1 foot = 0.3048m
6.5416 foot = 6.5416 × 0.3048 m
= 1.9938
Therefore, a height measurement of 6’6 1/2" is 1.99 metres tall.

A bacterium was found to contain a sequence of ATCGGGATCCT in its genome. A few generations later, the sequence was found to be ATCGGGGGGATCCT. What type of mutation caused this change in the bacteria?
Answer:
This question lacks options, the options are:
A) Deletion
B) Duplication
C) Inversion
D) Insertion
The correct answer is Insertion mutation
Explanation:
Mutation refers to changes that occur to the nucleotide sequence of a gene or DNA. Mutation produces different effect in the mutated organism and is classified based on how it occurs. Mutations can be deletion, insertion, duplication, inversion etc.
Based on the description of the mutation that occured to the bacterium sequence, it is an INSERTION MUTATION. An insertion mutation is a kind of mutation in which extra nucleotide bases are added to the original sequence. This is the case of this bacteria sequence, which was previously found to contain: ATCGGGATCCT.
After few generations, nucleotide bases "GGG" i.e three Guanine bases has been added to the sequence to give a mutated sequence: ATCGGGGGGATCCT.
Answer:
Duplication
Explanation:
Scientific Question: What is the effect of major flooding events on adult and juvenile trout
populations in Mack Creek?
Answer:
The population decreases.
Explanation:
Flood has a very adverse effect on the population of both adult and juvenile trout that lives in the streams because the trouts which has less than one year age are not good swimmers so they can't with stand with the fast flow of water during flood condition so the population of both adult and juvenile trout decreases in that stream in which flood occurs.
