<em> (A) G1</em>

Further explanation

all living things on this earth experience their respective cycles. For example a cycle when you are at the bottom, or a cycle when you are experiencing success

What exactly is the cell cycle? The cell cycle is a series of processes that occur in cells. There are 3 stages in 1 interphase that must be passed by a cell. The three stages are Gap 1, Synthesis, and Gap 2. What are the processes in the three stages?

G1

In Gap 1, there is a process of protein synthesis and multiplication of these cell organelles. In addition, cells also begin to grow in this section. Gap 1 is the longest step with a duration of about 11-12 hours. The DNA formed in this section only has 1 copy.

Synthesis

In contrast to Gap 1, there is DNA replication in the synthesis section. The process also takes place shorter, which is only 8 hours. Wow, it turns out DNA can also be replicated, yes! It turns out that not only buildings can be replicated.

G2

In the Gap 2 section, there is an unfinished process of organelle propagation in Gap 1. So there is a continuation of the process of organelle propagation that previously occurred in Gap 1. DNA has also been changed into 2 copies with a duration of 2-4 hours.

Now, after the cell has finished preparing for division, the cell will enter different stages of division, depending on the type of cell. if the body cell, the division that will occur is mitosis division, whereas if the cell is a gamete cell, then what will occur is meiosis division.

Answer:

(A) G1.

Explanation:

<u>The cell cycle consists of the following stages:</u>

1. G1

2. S (synthesis)

3. G2

4. M (mitosis)            

  4.1     Prophase

  4.2    Metaphase

  4.3     Anaphase

  4.4    Telophase

5. Cytokinesis

During the S phase the DNA replicates and the chromosome number doubles. For the rest of the cell cycle until cytokinesis, the DNA amount will be double that contained before S, in the G1 phase.

A new machine for harvesting corn will allow rows to be planted only fifteen inches apart, instead of the usual thirty inches. C
LUCKY_DIMON [66]

Answer:

A) With the closer spacing for the rows, the growing  corn plants will quickly form a dense canopy of leaves, which will, by shading the ground, minimize the need for costly weed control and irrigation.

Explanation:

If the space among plants is less, the shadow that they are going to produce is going to reduce the need of water, so they production will rise and the cost to maintain the crops will be less, so the producer can double the profits.

dynamic modeling of alpha-synuclein aggregation for the sporadic and genetic forms of parkinson's disease
Triss [41]

Numerous degenerative neurological conditions, most notably Parkinson's disease, have been linked to an excessive buildup of alpha synuclein (a-syn) in the brain. Intraneuronal inclusions, often known as Lewy bodies, are neuropathological characteristics seen in Parkinson's disease, Lewy body dementia, and other synucleopathies. The aggregation of a-syn is their main structural component. A-syn accumulation, aggregation, and ensuing Lewy body formation can be attributed to a variety of biological processes. These include genetic changes in parkin, synuclein, or the deubiquitinating enzyme ubiquitin C-terminal hydrolase (UCH-L1), which results in less efficient removal of a-syn via the ubiquitin proteasomal pathway (UPP). Additionally, environmental variables and an age-related decline in antioxidant defense mechanisms that heighten oxidative stress and can have an impact on the formation or clearance of a-syn are intracellular insults.

We focused on changes in the aggregation and clearance of a-syn as impacted by the UPP and the oxidative stress pathways in our dynamic models of a-syn processing in both normal and various disease states. A free radical profile similar to that observed in vivo after exposure to the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine is produced during simulation of enhanced oxidative stress (MPTP). To replicate the kinetics of a-syn that correlates to the neuropathology reported for the sporadic and hereditary types of Parkinson's disease, different model parameters of oxidative stress, UPP failure, or both routes are used. With the use of this in silico model, it is possible to evaluate the kinetics of pathway elements and more accurately identify and validate key pharmaceutical targets.

Which phrase is not an example of intercellular communication?
Dmitry [639]

Answer:

1.

Explanation:

A signal from one gland to another would not be intercellular, as "inter" means inside. This means intercellular would stand for "Inside the Cell"
