Answer:
What makes human hands unique? ... This long thumb and its ability to easily touch the other fingers allow humans to firmly grasp and manipulate objects of many different shapes. The human hand can grip with strength and with fine control, so it can throw a baseball or sign a name on the dotted line.
Humans, as well as monkeys, gorillas, and other primates, have a hand that can grip and grasp objects because they have an opposable thumb. The earliest primates were arboreal (they climbed trees), and so having grasping hands was an advantage in this environment. Human thumbs modified their ancestors’ opposable thumbs, making them more mobile and thus even more opposable.
describe the structure of an atom of argon-38 and argon-40
Answer:
Argon 38 has 18 proton and 20 neutron
Argon 40 has 18 proton and 22 neutron
Explanation:
isotope is same no of proton diff no of neutron
Both argon-38 and argon-40 have 18 protons but they have different atomic masses. The atomic mass of argon-38 is 38u while the atomic mass of argon-40 is 40u. Thus, they are isotopes.
What are isotopes? Some atoms contain the same number of protons (i.e. same atomic number) but they have a different number of neutrons (i.e. different mass numbers). These types of atoms are called isotopes.Argon element has three isotopes namely, argon-36, argon-38 and argon-40. All the three isotopes of argon have the same number of protons i.e. 18. But, all have different numbers of neutrons and thus, different mass numbers. Argon-36 has 18 neutrons, argon-38 has 20 neutrons and argon-40 has 22 neutrons. Thus, the mass numbers of argon-36, argon-38 and argon-40 are 36u, 38u and 40u respectively.Thus, the structure of an atom of argon-38 and argon-40 is slightly different as they are isotopes. Argon 40 has more atomic mass than argon-38. But, both contain the same number of protons. They have similar chemical properties but different physical properties.

in your own words, what is biodiversity?
Answer:
Biodiversity is all about the different living species we have on earth, such as animals, plants, bacteria, and including fungi. It also includes species that have not been discovered yet, along with microorganisms and invertebrates. Why is it important, you may ask? Well, Biodiversity prevents certain animals from being extinct, allows organisms to adapt to the environment around them, and in addition, provides an excessive amount of food and materials for survival. Lastly, Biodiversity helps support our Ecosystem, so in the long run, it can withstand and recover from a multitude of disasters.

(1) Addition of the first GlcNAc oligosaccharides to the asparagine residue of a protein
(2) Synthesis of phosphatidylcholine
(3) Degradation of misfolded ER protein
(4) O-linked glycosylation
Answer:
EELG
(1) Addition of the first GlcNAc oligosaccharides to the asparagine residue of a protein occurs in the Lumen of the Endopslamic Reticulum
(2) Synthesis of phosphatidylcholine occurs in the Endoplasmic Reticulum
(3) Degradation of misfolded ER protein ossurs in the Lysosome
(4) O-linked glycosylation occurs in the Golgiapparatus
Explanation:
1. The covalent attachment of a carbohydrate to a macromolecule such as proteins or lipids is known as glycosylation.
N-linked glycosylation is a very common form of glycosylation and it occurs in eukaryotes in the lumen of the endoplasmic reticulum.
The addition of the first GlcNAc oligosaccharides to the asparagine residue of a proteinmos an example of N-linked glycosylation.
2. Phosphatidylcholine is synthesized through the CDP-choline pathway which occurs at the cytoplasmic face of the endoplasmic reticulum. Choline entering the cell is immediately phosphorylated by choline kinase, converting choline to phosphocholine.
Phosphocholine is then converted to CDP-choline by the second enzyme in the pathway, CTP:phosphocholine cytidylyltransferase (CT).
The phosphocholine moiety is then added to diacylglycerol in a reaction catalyzed by CDP-choline:1,2-diacylgylcerol cholinephosphotransferase to complete the synthesis of phosphocholine.
3. Lysosomes are the cell organelles which are responsible for the breakdown of proteins as well as other components of the cell. Misfolded proteins are identified and transported to lysosomes through chaperone-mediated autophagy, macroautophagy and endocytosis, where they are then degraded.
4. O-linked glycosylation is a form of glycosylation that occurs in eukaryotes in the Golgi apparatus.

the length of bamboo grows much faster than that of thickness why?
Using a slow- and fast-growing variant of bamboo, Wei and colleagues looked at cell division, growth, and gene expression (through transcriptomics, which measures all the genes being expressed by an individual) to discover which genes may be responsible for fast growth in bamboo. They found that the slow-growing variant had reduced expression of genes relating to cell wall construction, the plant hormone auxin (important for cell growth and cell division), and had irregular cell growth and cell walls. Wei and colleagues suggest that a reduced ability to produce and perceive auxin, combined with a weakened cell wall, are responsible for the slow growth seen in the bamboo variant.

Most nerves of one of the sense organs go to the spinal cord before they go to the brain. Which organ is
this? (Think of your own body.)
Answer:
Umm every sense of organs travels in the spinal cord.
Most nerves of one of the sense organs go to the spinal cord before they go to the brain, and that organ is the one that is involved in the reflex action because it happens in a very short time and is controlled by the spinal cord before the brain..
What is the significance of the reflex action?Reflex actions are important because they allow the body to respond quickly to stimuli without waiting for the brain, and they can be especially important in situations where a quick response is necessary to avoid danger, such as when the hand touches hot substances and the hand suddenly goes back, which is due to the motor neuron action of the spinal cord.
Hence, most nerves of one of the sense organs go to the spinal cord before they go to the brain, and that organ is the one that is involved in the reflex action because it happens in a very short time and is controlled by the spinal cord before the brain.

Answer:
Look below
Explanation:
(A) A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing organic molecules originating in ancient photosynthesis that release energy in combustion
(B) After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Plankton decomposes into natural gas and oil, while plants become coal. Today, humans extract these resources through coal mining and the drilling of oil and gas wells on land and offshore.
(C) These non-renewable fuels, which include coal, oil, and natural gas, supply about 80 percent of the world's energy. They provide electricity, heat, and transportation, while also feeding the processes that make a huge range of products, from steel to plastics.

write a 5-7 sentence paragraph explaining what happens to co2 levels in the world over the course of the year. add as much context and details as you can
Answer:
The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. Respiration happens all the time, but dominates during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.

11. Question: Imagine 20 babies were born. 10 had blue eyes, and 10 had brown eyes. What traits do their parents probably have?
Answer:
The correct answer is - brown heterozygous Bb and blue eye bb.
Explanation:
In the provided question it is given that there are 20 babies born, 10 babies had blue eyes and 10 had brown eyes. As it is known that brown eyes are dominant over blue eyes, therefore, on the basis of this we can say that all blue-eyed babies have a bb genotype and as brown eyes are dominant traits babies must have at least one copy of the B allele which represents brown eye trait.
case1:
Parent 1 : bb
parent 2: BB
B B
b Bb Bb
b Bb Bb
there are 100% brown eye offspring so this is not the case
case 2:
Parent 1 : bb
parent 2: Bb
B b
b Bb bb
b Bb bb
here, 50% brown eyes and 50% blue eyes offspring produced thus, the parent trait will be brown heterozygous and blue eye.
