write the compliment triplets for the DNA sequence in each box in the following “ATG, ATC, GCA, AGT, AGC, GCC, GAT, AAG, TTG, CAG, TAG
Answer:
The complementary DNA sequence of each triplet is as follows:
ATG - TAC
ATC - TAG
GCA - CGT
AGT - TCA
AGC - TCG
GCC - CGG
GAT - CTA
AAG - TTC
TTG - AAC
CAG - GTC
TAG - ATC
Explanation:
A double-stranded DNA molecule is made up of two strands of DNA whose sequence are complementary to one another and linked by hydrogen bonds. According to the complementary base pairing rule as postulated by Chargaff, Adenine base will always hydrogen pair with Thymine base while Guanine base will always hydrogen pair with Cytosine base i.e. A-T, G-C
Based on the above explanation, the following triplets of DNA will have the following complementary sequences:
ATG - TAC
ATC - TAG
GCA - CGT
AGT - TCA
AGC - TCG
GCC - CGG
GAT - CTA
AAG - TTC
TTG - AAC
CAG - GTC
TAG - ATC
Artesian springs bring pressurized groundwater to the surface through which feature of Karst topography?
streams
caves
fissures
igneous rock
Answer:
The correct answer is D) Fissures
Explanation:
Karst is a topography or landform that is created by the dissolution of soluble rocks beneath the surface by waters from the surface or below.
Fissures are formed when because of earth movements there is the occurrence of a long, narrow opening, in the earth.
Artesian springs refer to the water coming out through these cracks or openings in the earth onto the surface of the Karst topography.

Some human white blood cells help destroy pathogenic bacteria by *
(1) causing mutations in the bacteria
(2) engulfing and digesting the bacteria
(3) producing toxins that compete with bacterial toxins
O (4) inserting part of their DNA into the bacterial cells
Answer:
2
Explanation:
They either engulfy and digest pathogens(phagocytosis) or produces antibodies.
Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.
Thus, By engulfing pathogenic bacteria through a process known as phagocytosis, some human white blood cells, notably phagocytes like neutrophils and macrophages, aid in the destruction of pathogenic germs.
These phagocytes have the capacity to identify and bind to bacteria, creating a phagosome—a membrane-bound compartment—around the bacterium.
The phagosome then joins forces with lysosomes, which are organelles that carry digesting enzymes, to create a phagolysosome. The bacteria are exposed to the lysosomal enzymes inside the phagolysosome, which causes them to break down and die.
Thus, Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

what is the greenhouse event primarily caused by
Explanation:
Greenhouse effect, a warming of Earth's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour , carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapour has the largest effect.
Capillaries are very thin, narrow blood vessels that allow for the transfer of oxygen, carbon dioxide, and nutrients. The image shows
how normal red blood cells and sickle-shaped red blood cells flow through a capillary,
Use information in the image to describe two ways that the sickle cell gene mutation affects the ability of red blood cells to perform
their normal function
Answer:
less packaging of oxygen
Explanation:
normal RBC (red blood cells) have a large surface area for oxygen packaging due to its biconcave shape but when mutation occurs the RBC being produced by the short bones is sickle shaped reducing surface area of haemoglobin exposed, responsible for packaging oxygen so tissues don't get right amount of oxygen

А
Use only alternative energies for the production of electricity
B
Require all new automobiles manufactured to run on electricity rather than gasoline.
с
Plant more trees and decrease deforestation practices so that more carbon dioxide can be absorbed from the atmosphere.
D
Require everybody to use mass transportation or methods of transportation that do not require burning fossil fuels, such as riding bicycles,
©2021 Illuminate Education Inc.
Answer:
hmm
Explanation:
On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
Plausible solution to human activities contributing to increasing amounts of carbon dioxide(carbon emission) in the atmosphere are :
Use only alternative energies for the production of electricityCarbon emission (greenhouse gas emissions) from human activities strengthen the greenhouse effect, causing climate change. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution.
Alternative energy is energy that is collected from renewable resources that are naturally replenished on a human timescale, hence contributing to betterment of environment.To know more about carbon emission here

A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPa, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl
Answer: hello your question is in complete below is the complete question
A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPA, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl = ViEi + EmVm? (note Vi + Vm= 1.) O 5.88 GPa O 5.66 GPa O 2.52 GPa O 6.74 GPa
answer : 5.88 GPa
Explanation:
Fiber reinforced composite containing e-glass fibers
E for the glass ( Ei ) = 72 GPa
E for the epoxy ( Em ) = 2.4 GPa
Determine the Elastic modulus of a composite containing 5% fibers
percentage of glass = 5% = Vi = 0.05
∴ percentage of epoxy = 95% ; Vm = 0.95
using the relation included in the question
Ecl = Ei Vi + Em Vm
= ( 72 * 0.05 ) + ( 2.4 * 0.95 )
= 3.6 + 2.28 = 5.88 GPa
Epinephrine initiates a signal transduction pathway that involves the production of cyclic AMP (cAMP) and leads to the breakdown of glycogen to glucose, a major source of energy for cells. But glycogen breakdown is only part of the fight-or-flight response that epinephrine brings about; the overall effect on the body includes increased heart rate and alertness, as well as a burst of energy. Given that caffeine blocks the activity of cAMP phosphodiesterase, propose a mechanism by which caffeine ingestion leads to heightened alertness and sleeplessness.
