HELO AGAIN PLS
Answer :Physical weathering happens especially in places places where there is little soil and few plants grow, such as in mountain regions and hot deserts.
Explanation:
2 stawberries picked at same time off same plant and left for 3 days in different conditions 1 decayed why
Even under high temperatures and low relative humidity conditions, storage life is typically short time. Calyx freshness was evaluated on a scale from 0 to 2, zero when calyx shows good quality, one when quality remains acceptable and two if it is no longer acceptable. Storage life is usually brief, even in high temperatures and low ratio conditions, therefore the one strawberry was decayed.
The best time to plant strawberries is within the spring, up to some weeks before the final frost date. You may extend your strawberry crop from late spring to early fall by choosing a variety spread of strawberry types. It takes roughly four weeks for June-bearing types from plant blossoming to fruit picking. Day-neutral and ever-bearing varieties both flower within the spring at roughly the same time and take roughly the same amount of time from flowering to harvest.
Counting on the variety chosen, one strawberry plant will provide 40 to 70 berries throughout the course of the season. This is often equivalent to fruit weighing between 0.7 and 1.4 kilogram’s (1.5 to 3.0 lbs) in weight. They’re perennial, strawberry plants grow year after year. The lifespan of a strawberry plant is roughly six years, however after the primary two years, fruit production noticeably declines.

write the complementary bases of the strand below according to the base pair rule. ATC CAG TAG GAC
Answer:
ATC CAG TAG GAC
R. TAG GTC ATC CTG
Explanation: According to the laws of Chargaff
T is "the complement" of A
C is "the complement" of G
and vice versa
Adenine(A) is complementary to thymine (T), and cytosine (C) is complementary to guanine (G). The complementary base of the DNA strand ATC CAG TAG GAC is TAG GTC ATC CTG.
What is the Chargaff Rule?
The Chargaff rule explains DNA base pairing. In DNA, the total number of purines is the same as the number of pyrimidines. A+G = C+T. Adenine (A) and guanine (G) are purines. Cytosine (C) and thymine (T) are pyrimidines. A purine makes a complementary base pair with a pyrimidine.
In normal conditions, adenine (A) makes a complementary bond with thymine (T), and guanine (G) makes a complementary bond with cytosine (C). Two hydrogen bonds are formed between adenine and thymine. Guanine and cytosine have three hydrogen bonds. Both strands of DNA are connected by hydrogen bonds among these nitrogenous bases. This gives stability to DNA, which remains in its double helical form.
Hence, the correct base pairing of ATC CAG TAG GAC is TAG GTC ATC CTG.

What would be the expected nuclear dna content of a primary spermatocyte in the same organism?.
1.65 picogram(s), that expected nuclear dna content of a primary spermatocyte in the same organism.
In a gamete (i.e. sperm or egg), the quantity of DNA is 1c, and the range of chromosomes is 1n. Upon fertilization, each the DNA content material and the range of chromosomes doubles to 2c and 2n, respectively.Because they're produced with the aid of using mitosis, number one spermatocytes, like spermatogonia, are diploid and feature forty six chromosomes.
Each number one spermatocytes is going thru the primary meiotic department, meiosis I, to provide secondary spermatocytes, every with 23 chromosomes (haploid).A unmarried number one spermatocyte offers upward thrust to 4 sperms after meiosis. Primary spermatocyte undergoes first meiotic department to provide secondary spermatocytes (haploid). The secondary spermatocytes produce 4 haploid spermatids after the second one meiotic department.

describe the major functions and components of the following systems of the body: integumentary, skeletal, muscular, and nervous.
The major functions and components of the following systems of the body
integumentary system - is one of the major organ systems that comprise skin, nails, hair, sweat glands, and sebaceous glands. It acts as the first line of defense from the external environment and works with other body systems to regulate body homeostasis.Skeletal system provides shape to the body, , protection and movement,.Muscle is a specialised tissue of mesodermal origin. About 40-50 per cent of the body weight of a human adult is contributed by muscles. They have special properties like excitability, contractility, extensibility and elasticity.Muscles have been classified using different criteria, namely location, appearance and nature of regulation of their activities. Based on their location, three types of muscles are identified : (i) Skeletal (ii) Visceral and (iii) Cardiac.
Nervous of all animals is composed of highly specialised cells called neurons which can detect, receive and transmit different kinds of stimuli. The neural organisation is very simple in lower invertebrates. For example, in Hydra it is composed of a network of neurons.The neural system is better organised in insects, where a brain is present along with a number of ganglia and neural tissues. The vertebrates have a moredeveloped neural system.

Define decision making and provide two strategies that one may use to make decisions.
Answer:
Decision making is the process of evaluating alternatives and making choices among them. Two strategies that one may use to make decisions is the additive strategy and the elimination-by-aspects strategy. The additive strategy involves creating a list of attributes that affect the decision and then rating each alternative based on each attribute. This strategy is often used for simple choices. The elimination-by-aspects strategy eliminates alternatives based on their attributes and evaluates each attribute in order of importance. This strategy is often used for complex choices

phosphodiesterases 3 and 4 differentially regulate the funny current, if, in mouse sinoatrial node myocytes
Sinoatrial node myocytes' cAMP (3′,5′-cyclic adenosine monophosphate) signaling is necessary for cardiac pace making both at rest and during the sympathetic fight-or-flight response (SAMs).
The cAMP-sensitive effectors responsible for pace making in SAMs include the cardiac "funny current" (If). cyclic nucleotide-sensitive, hyperpolarization-activated (HCN) channels are responsible for its production. cAMP either binds to the HCN channels directly or activates the cAMP-dependent protein kinase (PKA), phosphorylating them, to enhance the voltage-dependent gating of the channels. The mechanism limiting cAMP signaling to a PKA-dependent route is unclear, however PKA activity is necessary for signaling between adrenergic receptors (ARs) and HCN channels in SAMs. In different kinds of cardiomyocytes, PDEs hydrolyze cAMP and create cAMP signaling domains.
Here, we look at the function of PDEs in the control of If in SAMs. When PDE and PKA inhibitors were present or not, as well as before and after AR stimulation, it was detected in whole-cell voltage-clamp assays from acutely isolated mouse SAMs. The midpoint activation voltage (V1/2) of If at rest was depolarized by general PDE inhibition, which also eliminated the need for PKA in AR-to-HCN signaling.

Which of the following mutations will not result in a change to the amino acid sequence of a protein?
A)Frameshift mutation
B)Silent mutation
C)Neutral mutation
D)Nonsense mutation
Answer:
B)Silent mutation
Explanation:
A Silent Mutation is defined as a point mutation that does not change the amino acid. This occurs because more than one codon can code for the same amino acid. So while the protein was changed in the end there were no large-scale effects to the organism. This is why it is called a "silent" mutation because you cannot tell anything changes and there are no side effects.

What structural property of dna gave watson and crick the idea that dna replication was likely to proceed via a semiconservative mechanism?.
The complementary nature of base pairing between the two strands of DNA is the structural property of DNA that gave Watson and Crick the idea that DNA replication was likely to proceed via a semiconservative mechanism.
DNA is a double-helix structure made from nucleotides. The nucleotides of the DNA are made from nitrogenous bases, sugar, and a phosphate group.
The nucleotide bases which is complementary to each other form a ladder by which the structure of the DNA is maintained. Adenine pairs with Thymine and Cytosine pairs with Guanine of the other strand.
Each strand of the DNA acts as a template to form in a semi-conservative replication model.
It was due to the complementary nature of the DNA that Watson and Crick proposed the semiconservative model for DNA replication. Each DNA strand acts as a template through which a new strand is made that is complementary to it.

Most species of E. Coli are harmless or even helpful forms of bacteria that are found in the human intestine. E. Coli can aid humans in digestion and provide protection from other invading bacteria, but if the bacteria move to the human excretory system, they can replace other naturally occurring bacteria (Lactobaccilli). This can lead to bladder and kidney infections. Researchers found that by replenishing the excretory system with the naturally occurring bacteria, the infection caused by E. Coli is cured. Based on the research, what inference can researchers claim about the effect of bacteria?
Answer:
The inference is that bacteria can be pathogenic or characteristic of the commensal microbiota of different organs.
Explanation:
The human coexists with commensal micro-flora or commensal biota that are in balance and protect it from other pathogenic microorganisms, that is why we constantly live with a group of bacteria that do not generate pathological conditions in our body and even promote the stimulation of the immune response. .
When this balance is broken, pathogenic or opportunistic microorganisms invade, this is how they proliferate and generate infectious diseases that threaten the balance or state of human health.
