Explanation:
All of the following describe outcomes of urbanization except
O decreased soil pollution
O food chain disruption in a natural habitat
O increased wastewater from sewage drainage
O loss of plant biodiversity
Answer:
O decreased soil pollution
Explanation:
Urbanization does not lead to decreased soil pollution.
Pollution is the introduction of contaminants into the environments. As urbanization progresses and the population of people in a place increases, soil pollution increases.
Also, industrial expansion causes increased production of wastes. So, some of these wastes find their way into the environment of which the soil is a main component. There is an increased amount of soil pollution.Each body cell of a chimpanzee contains 48 chromosomes. After mitosis, how many chromosomes are present in each cell?
Answer:
During both mitosis and meiosis, DNA replicates first during S phase of interphase. Each copy (DNA molecule) is called chromatid. Before anaphase they remain together, joined by the centromere in the chromosome.
Part 1: How many chromatids and chromosomes are present at:
(a) anaphase of mitosis: During this phase sister chromatids split. We would have 48 chromosomes in each pole and 48 chromatides.
(b) anaphase I of meiosis: During this phase homologous chromosomes split, being a reductional division. In each pole we will have half the chromosomes we had after DNA replication. This is 24 chromosomes but 48 chromatides (remember they will split during anaphase II).
(c) anaphase II of meiosis: This is an equational division, we will have 24 chromosomes in each pole and 24 chromatides. Each chromatid is considered a chromosome.
(d) G1 prior to mitosis: During this phase DNA has not replicated yet and it is not condensed either. This formed is called chromatin. We will assign one chromatid for each chromosome. This is a somatic cell, so: 48 chromosomes and 48 chromatids.
(e) G2 prior to mitosis: After S phase, we have duplicated all chromosomes. We will assign two chromatids per chromosome: this is 96 chromatides and 48 chromosomes.
(f) G1 prior to meiosis: Before DNA duplication, 48 chromosomes, 48 chromatids.
(g) Prophase of meiosis I: After DNA replication, condensation of the chromatin takes place: 48 chromosomes, 96 chromatids.
Part 2: How many chromatids or chromosomes are present in:
(h) An oogonial cell prior to S phase: This is G1 phase, 48 chromosomes.
(i) A spermatide: This is the male haploid gametid, after meiosis: 24 chromosomes and 24 chromatids.
(j) A primary oocyte arrested prior to ovulation: They are arrested at prophase I of meiosis. This means their DNA is still duplicated and chromatides have not divided yet. 48 chromosomes and 96 chromatids.
(k) A secondary oocyte arrested prior to fertilization: They are halted at metaphase II of meiosis, meaning they have half the chromosomes (24) but chromatids are still together (48).
(l) A second polar body: They suffered the same process as the mature ovum but remained with little cytoplasm. They have 24 chromosomes and 24 chromatids.
(m) A chimpanzee sperm: They have completed both meiosis as well, they have 24 chromosomes and 24 chromatids.
Explanation:
Mitosis is a type of cell division in which the number of chromosomes in the parent cell is similar to the daughter cell. Mitosis occurs in the somatic cells.
The chromosomes present in the Chimpanzee's cell after mitosis are 48 chromosomes.
The mitosis can be explained as:
1. Mitosis is a type of cell division in which the number of chromosomes in the daughter and parent cells are similar.
2. During the DNA replication process, the DNA is duplicated and separated into the individual two daughter cells.
Thus, the cells with 48 chromosomes will give rise to daughter cells consisting of 48 chromosomes.

Decomposers, detrivores, and scavengers feed on dead organic material. How are decomposers different from scavengers and detrivores?.
Answer:
Okay, so a detrivore is a type of decomposer.
Basically, scavengers eat their food while decomposers do not eat the food, but instead break it down further externally.
The difference between a decomposer and the scavenger is that the scavenger is the one that consumes dead plants, animals or carrion to break down the organic materials into small particles.
The decomposer instead consumes the remains produced by the scavengers.
Examples of decomposers can be bacteria and fungi.
Examples of scavengers can be animals (like insects, birds, little critters)

the dysregulation of hormones may affect several pathways and processes in their body, which leads to risk in the emerging possibility for type ii diabetes, cardiovascular disease, infertility.
The most prevalent hormonal illness, polycystic ovarian syndrome, mostly affects adolescent girls as their hormonal balance and menstrual regularity mature.
Anovulation, dysmenorrhea, and amenorrhea are caused by the variability of menstrual hormones and other causes.The dysregulation of hormones may have an impact on a number of physiological pathways and functions, increasing the risk of type II diabetes, cardiovascular disease, and infertility.Genetics, neuroendocrine, lifestyle/environment, and obesity are among the risk factors that predispose people to PCOS. The pathophysiology of PCOS primarily focuses on hormonal disruption, insulin resistance, and hyperandrogenism causing poor folliculogenesis and increasing the risk of related comorbidities such endometrial cancer and type II diabetes.The explanation of potential treatments for controlling the syndrome coupled with lifestyle adjustment, which can be used singly or in combination depending on the symptoms.

newton's first law of motion shows that a net force is needes in order for an object to
Newton's first law of motion states that a net force is required for an object to move. Newton's first law of motion states that an object in motion tends to stay in motion unless acted upon by an external force.
Similarly, if an object is at rest, it will remain at rest unless an unbalanced force acts on it.
The law of inertia is Newton's first law. The object will continue to behave the same as if there was no net force. They either keep moving at a constant speed or remain stationary unless an unbalanced force acts on them. This unbalanced force changes velocity and/or direction depending on the magnitude of the direction of the resultant force. Newton's first law of motion is also known as the law of inertia.
According to Newton's first law, objects behave as expected. If the ball is on the table, it cannot roll or fall off the table. An object in motion does not change direction unless forced off course by a force.

All of the given structures are the part of the central nervous system.
What is Nervous System?According to biology's classical idea of the nervous system, an animal's nervous system is a highly sophisticated component that coordinates its movements and sensory data by sending and receiving signals from and to various regions of the body. In order to react to such occurrences, the nervous system and endocrine system collaborate to detect environmental changes that have an effect on the body.
Around 550–600 million years ago, worm-like invertebrates were the first to develop nervous tissue. The discovery of electrical impulses in plants and their utilization in recent decades, however, has called into question this conventional wisdom. These findings have led some researchers to suggest that plants have neural systems and that the science of plant neuroscience should be established.

Some researchers use fmri technology to study activity in the brain. What is the underlying activity detected by fmri?.
Some researchers use fMRI technology to study activity in the brain. The underlying activity detected by fMRI is by measuring the changes occurring in both oxygen amount present in the blood as well as the blood flow amount.
fMRI technology helps to detect the activity of the brain by measuring the changes occurring in both the amount of oxygen present in the blood as well as the amount of blood flow. This measurement is termed as the activity depending on the blood-oxygen level or called BOLD activity.
Functional magnetic resonance imaging or fMRI measures the activity of the brain by detecting various changes associated with the flow of blood. This technique will be relying on the fact of coupled activity of cerebral blood flow as well as neuronal activation. When an area of the brain is used up, there will be an increase in blood flow to that region.
The primary fMRI form uses contrast which is blood-oxygen-level dependent. This is a specialized brain type and a body scan that is used to map the activity of neurons in the brain or the spinal cord present in humans or in other animals by imaging the hemodynamic response which is related to the use of energy by the brain cells.
fMRI has come to dominate the mapping research of the brain as it does not involve injection uses, surgery, the ingestion of substances, and ionizing radiation exposure. This measure is usually corrupted by noise which is from various sources most frequently. Hence, the underlying signals are extracted by statistical procedures.
