Answer:
Explanation:
In terms of old school electron shells - One Hydrogen atom on it's own has an empty shell, and therefore to fill the shell it needs another electron. In the case of Helium, it already has two electrons at the same energy level - so it cannot accept any new electrons i.e. it cannot form new bonds.
Answer:
Hydrogen atoms can form a molecule as 2 hydrogen atoms together can result in a low energy combination of 2 electrons of the same energy level.
Explanation: Helium atoms already have 2 electrons of the same energy so therefore it cannot accept more.
In the microprogram for Mic-1, in if_icmpeq3, MDR is copied to H. A few lines later it is subtracted from TOS to check for equality. Surely it is better to have one statement here:
If cmpeq3 Z TOS MDR: rd Why is this not done?
The decision to perform two separate operations, copying the value from the memory data register (MDR) to the H register and then subtracting it from the top of the stack (TOS), instead of using a single comparison statement, might be attributed to the architecture and design choices of the Mic-1 microprogram.
One possible reason is that the Mic-1 microprogram architecture follows a more modular and sequential approach. By separating the steps into distinct microinstructions, it allows for better control and flexibility in handling intermediate results or performing additional operations before executing the comparison.
Additionally, breaking down the operations into separate steps might simplify the microinstruction sequencing and control logic, making it easier to implement and optimize. It could also allow for better error detection and handling by checking intermediate states during execution.

Which of the following scenarios would cause high compliance? A. High compliance would result in the lung collapsing on itself B. Increased production of elastic fibers in the alveolar walls C. Increased destruction of elastic fibers in the alveolar walls D. Decreased production of surfactant
High compliance would result from increased production of elastic fibers in the alveolar walls. This would enhance lung tissue elasticity, allowing for easier expansion during breathing, option B is correct.
Increased production of elastic fibers in the alveolar walls would lead to high compliance. Compliance refers to the lung's ability to expand and stretch in response to changes in pressure during breathing. Elastic fibers provide the lungs with their elastic properties, allowing them to easily stretch and recoil. When there is an increased production of elastic fibers, it enhances the overall elasticity of the lung tissue.
This increased elasticity means that the lungs can readily expand and accommodate a larger volume of air during inhalation. As a result, high compliance is achieved, enabling efficient and effective breathing, option B is correct.

Compare the concentration of connective tissue cells found in bone with the concentration of those found in blood.
Answer: CONNECTIVE TISSUE is the most abundant tissue in the body which are widely separated from each other and intercellular substance (matrix) is present in considerably larger amounts. The principal cell of connective tissue are fibroblasts which makes fibres found in almost all connectiv tissues. Some are solid and strong (bone), while others are fluid and flexible( blood).
Explanation:
Connective tissues usually contain fibres present in the matrix which may be of semisolid jelly-like consistency or dense and rigid, depending upon the position and function of the tissue. There are three main types of connective tissue which include:
--> Loose connective tissue
--> Dense connective tissue and
--> specialised connective tissue.
The bone and the blood are considered to be an example of specialised connective tissue. This is so because they both contain a number of different tissues with specialized cells and unique ground substances.
The BONE consists of osteoblasts, osteocytes, and osteoclasts. It is considered to be a specialised connective tissue because the bone cells are surrounded by a matrix of collagen fibres strengthened by inorganic salts, especially calcium and phosphate.
The BLOOD consists of red blood cells, white blood cells, platelets. It is considered to be a specialised connective tissue because the blood cells are surrounded by fluid matrix known as plasma and connecta with other cells through its transport functions.
In COMPARING the concentration of connective tissue cells or bone and blood, the connective tissue cells of bone comsist of fibre and collagen which makes it dense and rigid while the connective tissue cells of blood does not contain any fibre, therefore it's flexible.
Explain the concept of 'natural selection' and what it really means. Specify what
mechanism actually causes the natural selection and why it occurs.
Answer:
Natural selection is a proccess that occurs when an oganism is to weak to survive against other predators in that environementIt has failed to find a suitable nihe and evolution will cause it to become extinct from that geographic area.
Natural selection is the theory behind evolution put forth by Charles Darwin. Given the scarcity of resources in nature, animals with heritable features that promote survival and reproduction will typically produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.
Why is natural selection important?Charles Darwin's theory of evolution is known as natural selection. Animals with heritable qualities that aid in survival and reproduction will often generate more offspring than their contemporaries due to the limited resources in nature, increasing the frequency of such traits through subsequent generations.
Favorable features are passed down across generations as a result of natural selection. Natural selection may result in speciation, the process by which one species gives rise to another that is utterly separate.
It is one of the mechanisms that propels evolution and contributes to the understanding of the variety of life on Earth.
Thus, this is the main concept of natural selection.

When rock in the interior of the planet is heated to high enough temperatures, what occurs? Select the best answer from the choices below.
a it gets hotter and sinks into a trench
b the rock melts to create magma
c it forms new mountains underwater
d it causes glaciers to melt
Answer:
B !
Explanation:
I'm basing this off of a lesson I took two years ago, but the answer is B! The interior of Earth is rumored to be filled with magma as a way to have convection currents in itself, and to move the tectonic plates/ create the tectonic plates, if I remember correctly.
If i'm wrong I can still prove why it's not the other choices.
It's not A becuase when rock gets hotter, it rises, and when it cools, it sinks.
it's not C becuase it said "interior of the planet", which it may be referencing somewhere having to do to below the crust. as well, you need to cool rocks as to make it solid, not heated up rocks. but even then, mountains are made by the plates.
it's not D becuase glaciers are affected by climate change and occurrences the biosphere, not the interior of the planet.

how do dominant autosomal genes affect a punnett square and the probability?
Dominant autosomal genes have a specific effect on Punnett squares and the probability of inheriting certain traits. When a dominant allele is present, it only requires one copy of the allele to be expressed in the phenotype. In Punnett squares, the dominant allele is represented by a capital letter, while the recessive allele is represented by a lowercase letter.
When a parent with a dominant allele mates with a parent with a recessive allele, the Punnett square shows the possible combinations of alleles that their offspring can inherit. In this case, if the dominant allele is present in one of the parents, it will always be expressed in the phenotype of the offspring. Therefore, the probability of inheriting the dominant trait is 100% for offspring that receive the dominant allele.
For example, if a parent with the dominant allele (AA) mates with a parent with the recessive allele (aa), all of their offspring in the Punnett square will have the genotype Aa, and they will express the dominant trait. The probability of inheriting the dominant trait is 100% for these offspring.
Dominant autosomal genes in Punnett squares ensure that the dominant trait is expressed in the phenotype of the offspring when at least one copy of the dominant allele is present.

Ground shaking can transform wet sediments into liquid-like slurries in a process known as O a liquefaction O b. sloping O c slumping O d undercutting
Liquefaction occurs when the ground shaking transforms wet sediments into liquid-like slurries in a process known as liquefaction. The correct option is A) Liquefaction.
Liquefaction is a process where loose, unconsolidated soil loses its strength due to an increase in pore water pressure that reduces the effective stress between soil particles. Liquefaction is the tendency of soil to lose strength in response to earthquake shaking or other rapid loading. The ground behaves as a liquid because of the increase in pore water pressure that occurs as the soil particles are pressed against each other.
Liquefaction is a type of ground failure that occurs in saturated, loose, sandy soils due to seismic loading, and it has caused a lot of damage in past earthquakes. During an earthquake, the pore water pressure in the soil rises and reduces the soil's strength. The water-filled voids in the soil compress under increased stress, causing the soil to behave like a liquid and lose its ability to support the weight of buildings and other structures. This results in the collapse of buildings, bridges, and other infrastructure. Therefore, ground shaking can transform wet sediments into liquid-like slurries in a process known as liquefaction.

Following fertilization and two rounds of cell cleavage, each of the four cells of a frog embryo has a centriole that is preparing for the next cleavage. The centriole in each of these cells can trace its origins back to the original centriole provided by the _______ prior to the first cleavage. Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices secondary oocyte sperm ootid oogonium primary oocyte
Answer:
sperm
Explanation:
Centrioles are cylindrical organelles that play a major role during cell division, where they work to form the centrosome which duplicates and moves to opposite ends of the cell. The proximal centriole provided by the sperm cell mediates the separation of chromatids during the first cleavage of the fertilized egg. Upon fertilization, the proximal centriole forms the aster rays where microtubules act as a guide for the migration of the female pronucleus.
