what causes water to enter plant roots from the soil?
a. water concentration in root hairs and the soil are equal.
b.water concentration in root hairs and the xylem are equal.
c.water concentration in root hairs is higher than in the soil
d.water concentration in root hairs is lower than in the soil
Answer:
D
Explanation:
The cell sap is hypertonic to the soil therefore an osmotic gradient is formed and the roots therefore intake water
What causes water to enter plant roots from the soil is mainly because the concentration of water in the root hairs is lower than in the soil. The correct option would be D.
Water moves from the soil into the root by osmosis.Osmosis is the movement of water molecules from the region of high water potential or concentration to the region of low water potential or concentration.Hence, water will enters the plant roots from the soil because the water potential in the soil is more than that of the root airs.

A bacterium synthesizes DNA from each replication fork at a rate of 1000 nucleotides per second. This bacterium completely replicates its circular chromosome by theta replication in 30 min. How many base pairs does the chromosome contain
Answer:
180,000 nucleotide pairs = 180 kilobase pair (kbp) = 0.18 Megabase pairs (Mbp)
Explanation:
Synthesis rate = 1,000 nucleotides (nts) x second
1 minute = 60 seconds
30 minutes = 60 x 30 = 1,800 seconds
>> 1,800 seconds x 1,000 nuleotides per second = 180,000 nts
A typical bacterial genome contains approximately 5 Mbps of DNA that conforms a circular chromosome localized in the cytoplasm. In consequence, in this case the bacterial genome is small (0.18 Mbp).
DNA replication is a process in which the fragment gets replicated to form two indistinguishable replicas of itself. It is vital for the growth and passing of hereditary information to the newly produced daughter cells.
180,000 nucleotide pairs are formed in the replicating bacteria.
This can be calculated by:
[tex]\text{Synthesis rate} & = 1,000 \;\text{nucleotides (nts)} \times \text{ second}[/tex]
We know that 1 minute = 60 seconds So, 30 minutes = 60 x 30 = 1,800 seconds[tex]\text{1,800 seconds} \times \text{ 1,000 nucleotide per second} & = 180,000 \;\text{nts}[/tex]
The bacterial genome thus produced will have 180,000 nucleotide pairs or 180 kilo-base pairs (kbp) or 0.18 Megabase pairs (Mbp) in the chromosome.

Explain the plasma membrane in easy way.
Answer:
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.[

Answer:
The correct answer is option A, that is, light intensity and direction.
Explanation:
A photoreceptive organelle witnessed in the motile or flagellated cells of unicellular photosynthetic species like euglenoids and green algae is known as the stigma or the eyespot apparatus. It permits the cells of the organism to detect the intensity and direction of the light and react towards it.
This assists the organisms to either swim away from the light known as negative phototaxis, or to swim towards it known as positive phototaxis. The eyespots are the basic and the most typical eyes witnessed in nature. The eyespots comprise bright areas or orange and red granules of pigment and photoreceptors.

15%
D
Answer:
C. 15% 15% 35%
Explanation:
This follows the rules of base pairing. The amount of thymine (T) equals the amount of adenine (A), and the amount of guanine (G) equals the amount of cytosine (C).
Since thymine is equal to adenine and 35% of the bases is thymine, 35% of the bases is also adenine. This gives you a total of 70%.
35% + 35% = 70%
Now you need to figure out how much cytosine and guanine are in the bases. Since 70% of the bases are adenine and thymine, 30% will be cytosine and guanine.
100% - 70% = 30%
Since the amount of cytosine and guanine are equal, divide 30% by 2 to figure out how much each base takes of the total.
30/2 = 15%
Cytosine and guanine each take up 15% of the molecular bases.

Answer:
Explanation:
Vaccines are penetrations into the body system that helps improve the immune system against specific diseases.
The vaccines act by imitating the disease causing organism i.e they resemble the disease causing organism this is because they have been made form strains of the weak or dead disease organism.
The body system is made to identify this toxins or disease organism as something strange that needs to be remove anytime it reoccurs in the cell when the vaccines are taken. Although the body sees vaccine as something harmful they do not actually cause the disease but are pointers to the disease causing organism.

B. Periodic disturbances allow for coexistence.
C. Two species tended to use different resources.
D. The two species experienced interference competition and not exploitative competition.
The correct option C.
Two species tended to use different resources.
Explanation:
From Gause experiments on competing paramecium pairs, He found out that most times both species persisted and sometimes only one did because the two species uses different resources.
Organisms normally compete for limited resources in order to survive and one intend to compete well while other suffer. Both in the case of competing paramecium pairs, the pair use different resources which make the to persist and survive well. Once the resource of one finishes, the other one will persist because it is still surviving on its available resources.
II. PARTS OF THE DIGESTIVE TRACT A. ORAL CAVITY After ingestion, the physical breakdown of solid foods (mechanical digestion) begins in the oral cavity (mouth). Describe how food is mechanically digested in the oral cavity. Include a discussion of how the teeth, tongue, and saliva work together to convert solid food into a moist, semi-solid mass of food called a bolus. Example: think of how a hard, dry saltine cracker is converted into a moist ball (bolus) in the mouth. B. PHARYNX and ESOPHAGUS 1. After food has been mechanically digested, mixed with saliva, and a bolus has formed, it is swallowed. Swallowing moves the bolus from the mouth into the esophagus. Discuss the events that occur during swallowing. 2. Which portions of the pharynx does food pass through when swallowing
Answer:
This begins with the gradual breaking down of the food in the mouth, by grinding the food substances with the teeth this is mastication, and the secretion of saliva, which moisten the food, soften it so that the salivary amylase enzyme, carried out the mechanical digestion.
Swallowing is a wavelike muscular contraction which involve the contraction of the longitudinal and circular muscles of the oesophagus, which pushes the bolus down to the stomach.
The food pass Oropharynx. While the epiglottis prevents the bolus from entering the trachea.
This is followed by the rolling up of the tongue, the pushing the broken down food now chyme towards the back of the mouth, pressing it against the soft palate. At this stage a bolus is formed.From here it is pushed into the throat,where it is pushed down the oesophagus by peristalsis.
