Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water. It is attached at an inward pocket called the reservoir.
Alleles are described as ____________________. homologous chromosomes homologous chromosomes alternate versions of a gene alternate versions of a gene alternate phenotypes alternate phenotypes environmental factors that affect gene expression
Answers
Answer:
The correct answer is - alternate versions of a gene.
Explanation:
In a cell, if there are two copies of each chromosome, these are called homologous chromosomes, one come from the father and the other comes from the mother, which helps in promoting the variety and stability of a species.
Different or alternate versions of genes are possible that can result in two phenotypes for the same trait, these alternate versions called alleles. Alleles can be dominant and recessive.

Ecologists are interested in quantifying different kinds of biodiversity. In below study outlined here, which kind of biodiversity are ecologists studying?
Ecologists establish 20 small areas, called plots, randomly scattered across a California grassland. They count the number of different plant species present in each plot. By noting how many species appear in the plots, the ecologists are able to estimate the number of species in the entire grassland.
a. Genetic diversity
b. Functional diversity
c. Ecosystem diversity
d. Species diversity
Answers
Answer:
d. Species diversity
Explanation:
The species diversity can be measured by:
Species richness: Refers to the number of species are inhabiting a defined area. Species abundance: Describe the distribution of the species abundance.Species richness is the number of species present in a sample, within a community, habitat or microhabitat, ecosystem, landscape, region or any well-defined spatial unit. It is a metric for measuring biodiversity which simplicity and easy interpretation make it a standard metric. It is the simplest and straightforward measure of biodiversity. It is just a count of species, with no need for abundance data. In some cases, this can be the cause of criticism, as it ignores information about the species-abundance distribution.
All of these children (including the fraternal twin sisters in the front row)
are the biological children of the two parents in the middle of the picture.
Based on everything that you have learned in this unit, explain why these
brothers and sisters do not look exactly alike. Include the processes of cell
division and the rules of genetics in your answer.
Answers
Answer:
Explanation:
Because in the fetus stages of fraternal twins two different eggs get fertilized. Therefore, genetics won't be the same for both twins. But if they were identical twins the fertilized egg was to divide and the two zygotes would've carried the same genetics of each other.

5 The systolic blood pressure reading of 140-159 the systolic blood pressure reading of 140 - 159 is what stage of Hypertension?
A Stage 2
B Stage 1
C Stage 3
D High Normal
Answers
Answer:
B. Stage 1
Explanation:
Systolic blood pressure is less than 120 mm Hg and Diastolic less than 80 mm Hg so it is considered as normal. Pre-Hypertension occurs when the Systolic blood pressure is 120 - 139 and Diastolic pressure is 80 - 89. Stage 1 Hypertension is considered when the Systolic blood pressure is 140 - 159 and Diastolic blood pressure is 90- 99. If the Systolic blood pressure is greater than 160 it is considered as Stage 2 Hypertension.

Since grey squirrels can Camouflage... predators may not eat because the red squirrels die out. And grey squirrels may reproduce more because there is no competition anymore.
Fluorescent FM dyes partition reversibly into biological membranes without penetrating through them. Suppose that you have neurons cultured in a dish, and you incubate them with an FM dye for a period of time before washing the cells with excess medium to remove the dye.a)You find that if you stimulate the neurons to trigger action potentials during incubation with the dye, the synaptic regions of the neurons remain fluorescent after the wash. Propose an explanation for this effect.b)After you have generated fluorescent synaptic regions by this procedure, suppose that you trigger further action potentials while continuing to wash with excess medium. Would you expect the synaptic regions to lose fluorescence
Answers
Answer:
a) Emission observed is due to emission of synaptic vessels
b) Yes
Explanation:
a) Proposing an explanation
The emission observed ( the synaptic regions of the neurons remaining fluorescent ) is due to the emission on the synaptic vessels given that FM dyes have lipid-sensitive emission which can be loaded into a recycled synaptic vesicle
b)
The synaptic regions will lose fluorescence when you continue to wash with excess medium, also the more action potentials triggered the more observed emission. hence the increase in the loss of fluorescence is due to the fact that the emissions are not permanent
Earth's atmosphere is made of different gases that can affect the Earth's Climate in different ways
True/False
Explain in full details.
Answers
Answer:
True. The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures.Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere.
The statement is true.
Effect of atmosphere on climateAtmosphere of earth contains oxygen which we use for breathing. The gases present in the atmosphere such as ozone protects us from harmful ultraviolet solar radiation.
It creates the pressure without which liquid water couldn't exist on our planet's surface. The greenhouse gases warms our planet and keeps temperatures habitable for our living Earth.

. Luraine, who has blood type o, has a child with blood type B. She claims Will is the
child's father, but he denies this. Will's blood type is AB. How could blood typing
explain that will could, or could not be the father of this child?
Answers
Will can not be the parent as there is only one possible genotype composition of blood type AB being i^Ai^B.
If the mother's blood group is O and the father's blood group is AB, then the child's blood group could be A or B. Hence, Will could be his father.
What is blood group?Blood types are based on the presence or absence of specific antigens, which are chemicals that, if they are foreign to the body, may cause an immunological reaction.
Safe blood transfusions depend on proper blood typing and cross-matching since some antigens can cause a patient's immune system to attack the transfused blood.
In case of an emergency, it is crucial to know your blood type. You'll need compatible blood if you ever find yourself in a position where you need a blood transfusion. Blood cells can cluster together due to an incompatible blood group, which can be lethal.

The budding of clathrin-coated vesicles from eukaryotic plasma membrane fragments can be observed when adaptations, clathrin, and dynamin-GTP are added to the membrane preparation. What would you observe if you omitted (A) adaptations, (B) clathrin, or (C) dynamin
Answers
Answer:
Explanation:
Adaptins:
Adaptor proteins, which attach the clathrin to the membrane, are required for clathrin-coated vesicles to form. Clathrin cages form in solution at strong clathrin concentrations and under the right ionic environments and parameters, but they are empty hollow shells without membranes or other proteins. The data for clathrin baskets are included in the clathrin molecules themselves, as shown by the self-assembly of clathrin into baskets. Clathrin coat cannot form or build up without adjusting to the membrane it is attached to.
Clathrin:
Adaptins bind and act synergistically to specific receptors without clathrin, but no vesicles or clathrin are formed. There exists coated pits formations, but no clathrin coat.
Dynamin:
Clathrin-coated pits can develop and progress toward vesicle formation in the exclusion of dynamin, but the final step, known as membrane fusion, is inhibited. Consequently, in the exclusion of dynamin, strongly invaginated covered pits will be noticed. As a result, vesicles are unable to pinch the membrane.
Suppose plasma membrane fragments were prokaryotic cells, there would be no endocytosis and hence no adaptin or coatings. Endocytosis is not performed by prokaryotic cells. There are no receptors with adequate cytosolic tails in a prokaryotic cell that might facilitate the binding to adaptor proteins. As a result. no clathrin-coated vesicles will develop.
