The predatory bacterium Bdellovibrio bacteriovorus drills into a prey bacterium and, once inside, digests it. When the predatory bacterium attacks the gram-negative bacterium, what are the first structures penetrated by B. bacteriovorus on its way into the prey's cytoplasm
Answers
Answer:
The outer membrane, a peptidoglycan layer, periplasm, and cell membrane
Explanation:
The predatory bacterium will have to penetrate the cell wall and the cell membrane of the gram-negative bacterium before getting access to the cytoplasm.
In order to penetrate the cell wall of a gram-negative bacterium, the predatory bacterium will have to penetrate the components of the cell wall which consists of an outer membrane, a thin peptidoglycan layer, and a gel-like matrix known as the periplasm.
Thereafter, the predatory bacterium will have to penetrate the cell membrane before eventually getting access into the cytoplasm of the prey bacterium.
The peptidoglycan layer or the outer membrane will be the first structure penetrated by the B. bacteriovorus.
The attack of the predatory bacterium on the other bacterium:In the given case, the predatory bacterium, that is, B. bacteriovorus needs to penetrate the cell wall and the membrane of the gram-negative bacterium prior of getting within the cytoplasm of the host bacterium.
To penetrate the cell wall of a gram-negative bacterium, the predatory bacterium have to infiltrate the cell wall components comprising,
An outer membranePeriplasm, that is, the gel-like matrixA thin peptidoglycan layerThus, the predatory bacterium will first have to penetrate the peptidoglycan layer of the gram-negative bacterium.

In a population of 200, 86 individuals express the recessive phenotype. What percent of the population would you predict would be
heterozygous?
A. 65%
B. 55%
C. 35%
D. 45%
Answers
Answer:
The correct option is;
D. 45%
Explanation:
From the Hardy- Weinberg law, we have;
p² + 2·p·q + q² = 1
p + q = 1
Where:
p = Dom inant allele frequency in the population
q = Recessive allele frequency in the population
p² = The percentage of individuals in the population that are hom ozygous dominant
q² = The percentage of individuals in the population that are homo zygous recessive
2×p×q = The percentage of hete rozyous individuals in the population
The number of individuals that express the recessive phenotype = 86
The number of individuals in the population = 200
The percentage of individuals that express the recessive phenotype, q² = 86/200 = 0.43
Therefore;
q = √0.43 = 0.656
p + q = 1
p = 1 - q = 1 - 0.656= 0.344
∴ The frequency of individuals that express the do minant phe notype, p = 0.344
The percentage of heterozyous individuals in the population = 2×p×q × 100 = 2 × 0.656 × 0.344 × 100 = 45.15% ≈ 45%

The three traits of lifestyles that Archaea micro organism have are:not unusual characteristics of Archae bacteria known to this point are: (1) the presence of a feature of tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan mobile partitions, in most instances, in preference to a huge protein-wealthy coat; (three) the formation of ether-related lipids formed through phytanyl chains.
what's the difference among micro organism and archaea micro organism?Like micro organism, archaea have no inner membrane however both have cellular partitions and use flagella for swimming. Archaea differs from the reality that their cell wall does not include peptidoglycan and that the cell membrane makes use of ether-linked lipids rather than an ester connected to lipids in micro organism.

Answers
Answer:
2001
Explanation:
This question showcases a table that displays Mendel's results (figures) when he crossed pea plants and observed different characters in the plant. Mendel worked with different phenotypic characteristics in the pea plant.
According to the table, the result were for seven characteristics including height, flower color, flower position, pod color, pod shape, seed color, seed shape. Based on the observation of the number of F2 offsprings that possessed dominant trait and recessive trait for each character, we will notice that it follows an approximate phenotypic ratio of 3:1
1. Plant height 787 tall 277 short (3:1)
2. Flower color 705 purple 224 white (3:1)
3. Flower position 651 middle of stem 207 end of stem (3:1)
4. Pod color 428 green 152 yellow (3:1)
5. Pod shape 882 inflated 299 constricted (3:1)
6. Seed color 6,022 yellow X green
7. Seed shape 5,474 smooth 1,850 wrinkled (3:1)
This 3 dominant : 1 recessive ratio is the ratio got in the F2 offsprings when he observed the seven characteristics in pea plants. Hence, the seed color will also follow the same 3:1 ratio
Therefore, 2001 is the result Mendel obtained in the F2 offsprings for the recessive trait of seed color characteristics in his experiment, which actually depicts the 3:1 ratio. Hence, X (green seed color) is 2001
I believe that the answer is C. 2001

Drag each label to the correct location. Identify the cell organelles found only in plant cells and those found in both animal and plant cells. nucleus cell wall chloroplast Golgi apparatus cell membrane ribosome
Answers
Answer:
Plant cell: chloroplast, cell wall
animal and plant cells: nucleus, cell membrane, ribosome, golgi apparatus
Explanation:
The organelles that are specific to the plant cell only among the listed organelles include chloroplast and cell wall, while those found in both animal and plant cells include the nucleus, cell membrane, ribosome, and golgi apparatus.
The chloroplast contains the green pigment (the chlorophyll) that is present in all green plants. It is the organelle that confers greenness to plants and is therefore absent in animal cells. The rigid cell wall is only found in plant cells and this confers a kind of hexagonal shape to the cell, unlike the animal cell that lacks a rigid cell wall and therefore, shapeless.
All eukaryotic cells, including plant and animal cells, posses nucleus. It is an organelle that houses the genetic materials of the cell and acts as the control center of the cell. The cell membrane is also common to both cell and acts as a selectively permeable membrane to the cells. The ribosome is the organelle responsible for protein synthesis in both plant and animal cells while the golgi apparatus plays an important role in secretory pathway in both cells.

Why is ATP used as an active energy source over glucose? A. It is more abundant in food sources. B. It releases its energy quickly in a single reaction. C. It releases its energy slowly through multiple reactions, allowing it to last longer. D. It has more energy.
Answers
Answer:
B. It releases its energy quickly in a single reaction.
Explanation:
Adenosine triphosphate (ATP) is an energy carrying molecule in living systems while Glucose is an organic molecule (carbohydrate) that stores a high amount of energy. Glucose is a monosaccharide and the smallest unit of carbohydrate-containing foods we eat. Chemical energy is stored in the chemical bonds that hold the glucose molecule.
However, during the process of cellular respiration, energy stored in glucose molecule is broken down and transferred to ATP, which stores energy between the phosphate bonds of its molecule. The energy in ATP is released to perform cellular activities when the phosphate bond of the last phosphate molecule is broken.
Although the glucose molecule stores way more energy than ATP molecule, the ATP molecule releases its energy quickly in a single reaction. This makes energy readily available for cellular functions. This property of ATP makes it an active energy source over glucose.
Answer:
B. It releases its energy quickly in a single reaction.

The anemone's tentacles provide the clownfish with protection from predators, while the clownfish chase away butterfly fish that would eat the anemone. ... Sea anemones can do very little to control the flow of water across their bodies, and they rely on local currents to bring in oxygen and nutrients.Clownfish perform an elaborate dance with an anemone before taking up residence, gently touching its tentacles with different parts of their bodies until they are acclimated to their host. A layer of mucus on the clownfish's skin makes it immune to the fish-eating anemone's lethal sting.Instead, both species have evolved behaviors that help them avoid being eaten while they graze for benthic algae. Butterflyfish typically swim in pairs near a particular clump of coral. ... An anemone robbed of its clownfish guards will quickly fall prey to the voracious butterflyfish.
