You and your friends go to the beach for vacation. You all walk down to the beach to go swimming. When you get there, you see the water is murky and green, and there are algae blooms floating on top. If it is excess nutrients which are feeding the algae blooms and lowering the oxygen content in the water, that process is called:_______.a. nutrient cycling.
b. nitrification.
c. eutrophication.
d. hypoxia.
Answer: The process is called EUTROPHICATION. The correct option is C.
Explanation:
Eutrophication is a type of environmental pollution where by there is an increase in nutrient salts of a water body which can lead to structural changes in the affected aquatic ecosystem. These changes includes:
--> Increase in production of algae: this effect causes algae blooms which makes the water murky, greenish and unpleasant for certain activities such as swimming.
--> Decrease in aquatic life: the presence of excessive growth of algae which are often degraded by microorganisms. When the rate of degradation of the algae by microorganisms is greater than that of oxygen regeneration a hypoxic state occurs which is harmful to aquatic life example fishes.

While there is only one species of Galapagos Island tortoise, there are several subspecies. Larger islands with more wet highlands have lush vegetation near the ground. Tortoises there tend to have high-domed shells and shorter necks, which restrict upward head movement. They also have shorter limbs. They are the heaviest and largest of the subspecies. Smaller drier islands are inhabited by tortoises with longer necks and limbs and with shells that are elevated above the neck, which allow them to browse taller vegetation. Based on the information given, which is a plausible explanation for the ancestry of the tortoise subspecies?
Answer:
Tortoises with better adaptations in shell shape and leg length were selected to exploit the food resources on each island and, thus, they were capable of having more offspring.
Explanation:
Natural selection can be defined as the process of differential survival and reproduction in a given environment due to differences in their phenotypic traits. Thus, these phenotypic traits are selected to be better adapted to their environment. As a consequence of natural selection, organisms evolve by changing their phenotype frequencies over many generations. In this case, phenotypic differences are expressed as variations in shell shape and leg length, which are adaptive traits that were selected on each island.
Answer: D. Individuals with different adaptations in shell shape and leg length best exploited the food resource and left more surviving offspring in each island.
Formed when caves can no longer support the dirt above it.
Answer:
Collapse dolines.
Explanation:
A doline is a special type of geological depression characteristic of karst reliefs. These reliefs are formed by the chemical weathering of rocks made of minerals that are soluble in water. In general, dolines are found in places where rocks are composed of limestone and clay in different proportions. When the calcium carbonate of limestone gets in contact with the rainwater, turns into calcium bicarbonate, which is soluble in the presence of water. Clay then deposits in lower areas originating the dolines or depressions.
Dolines might be formed by dissolution (the soil is dissolved in pluvial water that first flood and then infiltrate) or by collapsing. Collapse dolines occur because first, soluble material in lower layers formes a cavity underground. Soluble material flow to lower areas making a place to a cavity or hole under the ground. It gets bigger with time as the material in the bottom keeps being removed. It reaches a point in which the cave can no longer support the roof material, such as rocks, soil, and vegetables, and ends collapsing.
Which type of mining is likely the least harmful to the environment?
a. surface mining
b. placer mining
c. subsurface mining
d. none of the above
Answer:
Placer mining
Explanation:
Placer mining can be less damaging to the environment than surface mines, as the sediment is returned to the water after the minerals have been extracted.
The mining that is likely the least harmful to the environment is the placer mining that is present in Option B, water is used in placer mining to separate mineral particles from soil.
What is placer mining?Placer mining involves the extraction of minerals from riverbeds, streambeds, and other bodies of water, and this method involves the use of water to separate mineral particles from soil, while placer mining is generally considered to be less harmful to the environment compared to surface and subsurface mining, but it can still have negative impacts if not properly managed. For example, the use of mercury in the gold extraction process can lead to water pollution and harm to aquatic life.
Hence, the mining that is likely the least harmful to the environment is the placer mining that is present in Option B.

B. endothermic
c. enzymes
D. exothermic
Step 1: Add approximately 25 mL of water to a 50-mL graduated cylinder.
Step 2: Measure and record the initial volume of the water to the nearest 0.1 mL.
Step 3: Carefully slide the object into the graduated cylinder. Measure and record the final volume of the water to the nearest 0.1 mL.
Step 4: Determine the volume of the object by subtracting the measurements in steps 2 and 3.
What pattern in these data could be used to predict the final volume if the initial volume is known?
The final volume is the sum of the initial volume and the volume of the object.
The initial volume is the sum of the final volume and the volume of the object.
The volume of the object is the sum of the initial volume and the final volume.
The final volume is the difference between the initial volume and the object’s volume.
Answer:
The final volume is the sum of the initial volume and the volume of the object.
Explanation:
Since we know that the volume of the object is the difference between the final and the initial volume, let the volume of the object be ∆V, let the initial volume be V1 and let the final volume be V2.
From;
∆V= V2 - V1
V2= ∆V + V1

C.
The structure of the protein could be changed.
D.
The mutation could change every protein in the cell.
Answer:
1. The true statement about the relationship between an organism's traits and its genes is that genes encode the proteins that determine an organism's traits (option B).
2. A DNA mutation can cause the structure of the protein to be changed (option C).
Explanation:
DNA contains the genetic information necessary for the structure and function of living beings. It is a molecule that, once transcribed into mRNA, dictates the rules for protein synthesis.
1. Chromosomes are composed of a DNA molecule, whose segments form the genes that contain specific base sequences to determine a trait.
The information from the DNA is transcribed into the mRNA, which is responsible for carrying it to the cytoplasm where protein synthesis occurs. These proteins formed from the genetic code determine the different traits in living beings. So, genes encode the proteins that determine an organism's traits.
2. Since the DNA contains the information needed to transcribe it into the mRNA and for the mRNA to initiate protein synthesis, any alteration in the DNA base sequence -due to mutation- can be produced:
A transcription of the mRNA with the alteration That during mRNA translation, the codon that forms an amino acid, or that determines the stop of protein synthesis, is changed. The alteration or change, consequently, of the synthesized protein.There is a relationship between the DNA mutation and the structure of the protein being changed.

PLEASE HELP I WILL MARK BRAINLY
THANK YOU
Due to the higher concentration of oxygen in the air than your blood, oxygen goes from the lungs into the red blood cells by simple diffusion.
It should be noted that oxygen diffuses from the lungs into the red blood cells. It then binds to hemoglobin. A molecule of hemoglobin can bind with four molecules of oxygen.
Since the red blood cells have cell membranes that are thin, this then enables oxygen to be able to diffuse quickly.
In conclusion, the correct option is simple diffusion.

What stages of replication do both cycles have in common? Describe the virion action at each of these stages.
Answer:
Attachment, Penetration and Replication
Explanation:
A bacteriophage is a virus that attacks bacterial cells. The lytic and lysogenic cycles are two methods of viral replication. In the lytic cycle, the virions produced are released from the host cell whereas in the lysogenic cycle, viral nucleic material are incorporated into host nucleic material and are copied to daughter cells when the host cell reproduces. The common steps in both cycles are given below:
1 Attachment – in this step, the bacteriophage attaches itself to the surface of the host cell so as to insert its DNA into the host cell.
2. Penetration – the virus inserts its DNA into the host cell by penetrating the cell membrane of the host cell.
3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism.
