Blood type is a genetically determined trait. Two siblings donate blood and find out their blood types. The brother is Type A and the sister is Type
B. Which of the following best explains why the siblings have different blood types?
A. The brother has a different number of blood type genes than his sister.
B. The brother's blood type gene is on a different chromosome than his sister's.
c. The brother has different alleles for the blood type gene than his sister does. D. The brother has a different number of chromosomes than his sisted does
Answer:
C
Explanation:
The brother has different alleles for the blood type gene than his sister does. Blood type is inherited from parents like many other traits that can be displayed on a punnet square. Depending on what the parents blood type alleles were, the brother and sister could have different blood types.
A different number of chromosomes doesn't lead to different blood types, so D is wrong. And A is incorrect because the number genes also does not affect blood type. And I think the blood type genes are on the same chromosome, so B is wrong. C is correct because blood type is inherited by alleles, and different alleles can cause different traits, such as blood types.

Why is it important to have range of tools that can measure all parts of the electromagnetic spectrum
This tiny slice of the universe, speckled with galaxies near and far, tells the story of galaxy evolution over cosmic time Among the 10,000 or so galaxies
pictured here are newborns, adolescents, adults and retirees Like looking through a vast collection of family photos, astronomers are poring over this
comprehensive image to see how galaxies grew up, matured, and aged
This portrait of our universe's history is called the Hubble Ultra Deep Field (or HUDF). It is a minuscule patch of sky first targeted by the Hubble Space
Telescope in 2002 and revisited over and over again since then. This version of the HUDF is extra special though It combines observations of the field
taken with Hubble's Advanced Camera for Surveys and the Wide Field Camera 3 from 2002 to 2012, providing one of the farthest views into the universe
we've ever seen Plus, it includes light not just from the visible part of the spectrum but from the invisible) infrared and ultraviolet ranges, too, giving us
different details of the story of how galaxies came to be
Infrared light lets us see the universe's youngest galaxies. These galaxies lie far far away from us, and as their light travels across the universe, it gets
stretched by the expansion of space Wavelengths of visible light grow longer becoming infrared light by the time it reaches us Combining Hubble's
observations of the HUDF in visible and infrared light a team of astronomers led by Garth Illingworth of the University of California identified more than
5,500 galaxies in a central portion of the field some so faint that they are just one ten-billionth the brightness of what the human eye can see Another
team headed by Richard Ellis of the California Institute of Technology (Caltech) used Hubble's infrared observations to find galaxies more than 13 billion
light-years away, when the universe was only about 400 million years old - or about three percent of its present age
Alternatively, to understand slightly older growing galaxies that are not so far away, observing in ultraviolet light is best The hottest and youngest stars
give off huge amounts of ultraviolet light making them easy to spot at those wavelengths of light Most recently, a team of astronomers led by Harry
Teplitz of Caltech used the ultraviolet-sensing abilities of Hubble's Wide Field Camera 3 to add the ultraviolet piece to this view of the HUDF With this
part of the galaxy evolution picture in hand, astronomers are investigating how galaxies grew through bursts of star formation and exactly where when
and how many stars formed over time
Because our atmosphere blocks or absorbs most infrared and ultraviolet light that reaches Earth only a telescope in space, like Hubble, can provide
such insights into the history of galaxies Without both infrared and ultraviolet light, the tale is incomplete.
Answer:
the inly question i understood ::::: Why is it important to have range of tools that can measure all parts of the electromagnetic spectrum
ans
Because the electromagnetic spectrum comprises different types of electromagnetic radiation (radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays), all of which have different wavelengths and require different tools to measure them.

Describe the process of creating a designer baby.
Answer:
The term 'designer baby' refers to a baby that has been given special traits through genetic engineering. This is done by altering the genes of the egg, sperm, or embryo. These traits can, in theory, vary from lower resistance to diseases to even gender selection

if an organism is a prokaryote, unicellular and can survive in harsh conditions, in which doiman would it be classified
Answer:
The correct answer is - Archaea.
Explanation:
Archaea is one of the three domains of life other than bacteria and eukarya. Archaea are prokaryotic organisms that are unicellular and present in very extreme conditions like salt environments or extreme heat.
Archaea used to be placed with bacteria but due to some closeness with the characteristic of eukarya as well as bacteria, it is placed as a separate domain. It lacks nuclei and has a cell wall in its cell.

1. Describe the possible fates of blood lactate? (4 mrks)
2. Does gender affect the levels of lactate? If so, Why? (4mrks)
Answer:
1)When the oxygen level is low, carbohydrates break down for energy and produce lactic acid. Lactic acid levels rise with strenuous exercise or other conditions - such as heart failure, severe infection (sepsis), or shock - which reduces the flow of blood and oxygen throughout the body.
2) no gender differences in resting or peak blood lactate concentrations, nor in the rate of blood lactate removal of young adult men and women with similar aerobic fitness level expressed as ml.kg FFW1

8. Outline the process of metaphase, inclusive of the role of microtubules and the centromere.
Answer:
Chromosomes are positioned in the middle of the cell during metaphase.
Explanation:
During metaphase, the centrosomes are at opposite poles or sides of the cell. The spindle apparatus is formed and the nuclear membrane has dissolved. The spindle fibers, also known as microtubules have lined up the chromosomes along the equatorial plate in the middle of the cell so each sister chromatid faces opposite directions. The sister chromatids are still connected by the centromere, and this is the last time they are connected during this division. The centromere is also where kinetochores assemble, and kinetochores are the sites of attachment for microtubules to pull the sister chromatids apart. They are important for the cell to be able to divide.
what is cellular respiration also called
Answer:
Krebs cycle, tricarboxylic acid cycle.
Explanation:
Cellular respiration is what cells do to break up sugars to get energy they can use. ... Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain.
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules[1] or nutrients into adenosine triphosphate (ATP), and then release waste products.[2] The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen,[3] are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.
Nutrients that are commonly used by animal and plant cells in respiration include sugar, amino acids and fatty acids, and the most common oxidizing agent providing most of the chemical energy is molecular oxygen (O2).[1] The chemical energy stored in ATP (the bond of its third phosphate group to the rest of the molecule can be broken allowing more stable products to form, thereby releasing energy for use by the cell) can then be used to drive processes requiring energy, including biosynthesis, locomotion or transport of molecules across cell membranes.
Answer:
Alternative Titles: cell respiration, tissue respiration. Discover how cellular respiration transforms your food into energy usable by your cells. Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.
Explanation:
Plants take in carbon dioxide and release gas
Answer:
yes, but by gas you mean oxygen right?
Explanation:
Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

4. Which part of the replication process helps reduce the chance for genetic mutation?
a. insertion of RNA primer sequences
b. sealing the gaps between fragments
c. opening multiple origins of replication
d. proofreading new DNA strands
Answer:
D
Explanation:
Key points:
- Cells have a variety of mechanisms to prevent mutations, or permanent changes in DNA sequence.
- During DNA synthesis, most DNA polymerases "check their work," fixing the majority of mispaired bases in a process called proofreading.
- Immediately after DNA synthesis, any remaining mispaired bases can be detected and replaced in a process called mismatch repair.
- If DNA gets damaged, it can be repaired by various mechanisms, including chemical reversal, excision repair, and double-stranded break repair.

Which word describes the speed at which the "global
conveyor belt" moves?
Answer:
The conveyor belt moves at much slower speeds (a few centimeters per second) than wind-driven or tidal currents (tens to hundreds of centimeters per second). It is estimated that any given cubic meter of water takes about 1,000 years to complete the journey along the global conveyor belt
