Which toxin is of particular concern for the infected host if antibiotics are used resulting in mass pathogen lysis? Cholera toxin Tetanus toxin Botulinum toxin Endotoxin​

Answers

Answer 1

Answer: Endotoxin

Explanation:

Antibiotics generally target the cell walls of bacteria with the aim to dissolve it so that the body's immune system can be better able to attack it. When the antibiotics target these cell walls, pathogen lysis occurs and ruptures the cell.

Endotoxins are located in those cell walls and once free, are a source of concern because they can cause an array of medical problems with inflammation being amongst the mildest.

b. taproot: 5. Carrot

c. lateral buds: 2. Brussels sprouts

d. modified stem: 6. Potato

e. leaf (petiole and blade): 4. Spinach    

f. petiole: 3. Celery

Explanation:

A plant stem is one of the structural axes of vascular plants that holds structures such as leaves, flowers, and fruits. The stem also transports water and dissolved (organic and inorganic) nutrients between the roots and the shoots. In some plants, the stem is modified in order to carry out other functions (e.g., storage, vegetative propagation, protection, etc). Potatoes are modified stems (i.e., stem tubers) ​that are connected by small stem sections known as stolons, and serve as food storage organs. A taproot is a central, and dominant root from which other roots sprout, which can be used by the plant to store water and food (e.g., in carrots and turnips). Lateral buds or axillary buds are meristematic regions growing from the axils of the leaves at the intersection of the leaf and stem, below the terminal bud. Leaves are composed of the 1-blade, also known as the lamina, which is the largest part of the leaf, and 2-the petiole, which is a stalk that supports the blade and connects it to the plant stem. Celery petioles play the same functions as a plant stem by acting as transport and storage organs.

Answers

I'm not 100% sure what the exact answer is to this, because lots of things could be said about what gametes need to do for reproduction.

I suppose since it says that it's combining with another cell, it's hinting at the fact that reproductive cells are haploid.

If this is multiple choice I would choose the choice that has to do with gametes being haploid.

A reproductive cell must differ from other normal body. The reproductive cell must Haploid because it will soon fuse with another reproductive cell to form a new individual.

Which of the following statements regarding membrane protein function is false? Group of answer choices Membrane proteins act as receptors to molecules like hormones. Membrane proteins serve as enzymes. Membrane proteins form junctions between cells. Membrane proteins transfer genetic information to the cytoplasm.

Answers

Answer:  

Membrane proteins transfer genetic information to the cytoplasm.

Explanation:

Membrane proteins cannot transfer genetic information to the cytoplasm. Genetic information is only in DNA and RNA, and to pass it, RNA has to leave the nucleus and be translated into a protein in the cytoplasm. Once the protein synthesis has finished, the protein may go to the membrane if it has the signal to do it or have a different function. In the membrane, the membrane protein can receive information from other cells and transfer it to the cytoplasm, but never in the shape of genetic information.

what are the biological structures

Answers

Answer:Biological structures are able to adapt their growth to external mechanical stimuli and impacts. For example, when plants are under external loads, such as wind force and self-weight, the overloaded zones are reinforced by local growth acceleration and the unloaded zones stop growing or even shrink. Such phenomena are recorded in the annual rings of trees. Through his observation of the stems of spruce, K. Metzger, a German forester and author, realized that the final goal of the adaptive growth exhibited by biological structures over time is to achieve uniform stress distribution within them. He published his discovery in 1893.12 A team of scientists at Karlsruhe Research Centre adopted Metzger's observations and developed them to one single design rule: the axiom of uniform stress. The methods derived from this rule are simple and brutally successful like nature itself. An excellent account of the uniform-stress axiom and the optimization methods derived from it is given by Claus Mattheck in his book ‘Design in Nature’.13 The present study utilizes one of these methods, stress-induced material transformation (SMT), to optimize the cavity shape of dental restorations.

A the chromosomes are highlighted
B. the centrioles are formed
C chromatids separate
D. the homologous chromosomes are paired AND the spindle is formed

Answers

Answer:

D. the homologous chromosomes are paired AND the spindle is formed

Explanation:

Meiosis is the type of cell division that results in four daughter cells with each having a reduced number of chromosomes (by half). Both meiosis and mitosis occur in different stages including prophase, metaphase, anaphase etc but meiosis occurs in two series of division processes called meiosis I and meiosis II.

In prophase I of meiosis, homologous chromosomes, which are similar but non-identical chromosomes from male and female parents pair to form tetrad or bivalent. This pairing of homologous chromosome is unique and peculiar to MEIOSIS but never mitosis.

21 Science 6 - CR Calculating the Density of Propane Use the mass and volume data to calculate the density of liquid propane to the nearest hundredth. Mass of propane = 4,300 g Volume of propane = 10,000 mL The density of liquid propane is g/mL. Intro​

Answers

Answer:

0.43g/mL

Explanation:

Density of a substance is its mass per unit volume. It can be calculated thus:

Density = mass/volume

According to the information provided on propane in this question;

Mass of propane = 4,300g

Volume of propane = 10,000mL

Density = 4300/10000

Density = 0.43g/mL

Hence, the density of propane is 0.43g/mL.

You isolate a variant of the Hfr parent in question 6 that only shows recombination of the his+ and trp+ genes. The cross was ( HFR lac+, gal+, trp+, his+, strr X F- lac-, gal-, trp-, his-, strs ). This strain most likely:_________.
a. Contains an F' his+ trp
b. Has become F-
c. Contains an Hfr translocation
d. No longer mates as a merry diploid
e. Not enough information is given

Answers

Answer:

The correct answer is - b. has become F-.

Explanation:

In the case of the cross of two different strains, some genetic material moves to the F- strain from the Hfr strain, but due to genome size, it's not possible that all the genes can pass into a single bacterium.

Instead of complete transfer, each individual F- cell gets a different and random subset of genes from the Hfr. There is no translocation and F' does not contain  his+ trp+.

The scientists mapping the SNPs in the human genome noticed that groups of SNPs tended to be inherited together, in blocks known as haplotypes, ranging in length from 5,000 to 200,000 base pairs. There are as few as four or five commonly occurring combinations of SNPs per haplotype. Integrating what you've learned throughout this chapter and this unit, propose an explanation for this observation.

Answers

Answer:

SNPs have shown that only 0.1 % of DNA sequences are different in the human genome between different individuals, thereby all the inherited phenotypic variation observed in our species is associated with only 0.1 % of differences at the genome level  

Explanation:

Haplotypes are block-like sequences of DNA that are inherited together due to low recombination rates. Moreover, single-nucleotide polymorphism (SNP) mapping is a very useful methodology used to map the site of SNP mutations (i.e., SNP variants). In this regard, it has been observed that there are approximately 10 million common SNPs in the human genome. These SNPs contribute to the wide range of phenotypic variation observed in human populations for different traits (e.g., eye color, hair, weight, height, etc). Moreover, researchers have determined that SNPs can be clustered into haplotypes, thereby haplotypes can be accurately sampled by as few as approx. 300,000 selected SNPs, which are sufficient to represent all of the genetic variation across different human genomes.

Recall that one approach to the study of cell cycle regulation has been to fuse cultured cells that are at different stages of the cell cycle and observe the effect of the fusion on the nuclei of the fused cells (heterokaryons). When cells in Gl are fused with cells in S, the nuclei from the Gl cells begin DNA replication earlier than they would have if they had not been fused. In fusions of cells in G2 and S, however, nuclei continue their previous activities, apparently uninfluenced by the fusion. Fusions between mitotic cells and interphase cells always lead to chromatin condensation in the nonmitotic nuclei. Based on these results, identify each of the following statements about cell cycle regulation as probably true (T), probably false (F), or not possible to conclude from the data (NP). Sort each statement into the appropriate bin.
1. The transition from mitosis to G1 appears to result from the disappearance or inactivation of a cytoplasmic factor present during M-phase.
2. The activation of DNA synthesis may result from the stimulatory of one or more cytoplasmic factors.
3. Gl is not an obligatory phase of all cell cycles
4. The transition from G2 to mitosis may result from the presence in the G2 cytoplasm of one or more factors that induce chromatin formation.
5. The transition from S to G2 may result from the presence of a cytoplasmic factor that inhibits DNA synthesis.
A. T
B. F

Answers

Answer:

1. T

2. T

3. NP

4. F

5. F

Explanation:

In somatic cells, the cell cycle can be divided into 1-the interphase, 2-the mitotic phase or M phase, and 3-the G₀ phase. In turn, the interphase of the cell cycle can be divided into three phases: 1-the gap 1 (G1) phase or growth 1 phase, 2-the S phase (DNA replication or DNA synthesis), and 3-the gap 2 (G2) phase or growth 2 phase. During the G1 phase, the cell synthesizes key enzymes which are required during DNA replication (S phase) and cell division (M phase). Cytoplasmic factors are proteins and messenger RNAs (mRNAs) that control cell functions during the cell cycle. This cycle is modulated by proteins known as control factors, i.e., cyclins and cyclin-dependent kinases (Cdks) that work together to control the progression through different phases of the cell cycle. The transition from S to G2 occurs after DNA replication. This transition (S to G2) is controlled by a DNA damage checkpoint orchestrated by the ATM (Ataxia telangiectasia mutated) and ATR (Ataxia Telangiectasia and Rad3 related) kinases which are recruited to DNA damage sites. Moreover, the ​transition from G2 to M phase is mediated by the accumulation of mitotic inducers, which lead to an increase in the activity of mitotic kinase and finally trigger mitotic entry.
