Low oxygen near the Gulf's bottom kills most marine life. Fish, shrimp, and crabs swim away from low oxygen, but other species are stressed or killed. Summertime brings the Gulf of Mexico dead zone.
What is a dead zone?The most severe impact of eutrophication is dead zones. Massive algal blooms are brought on by this abrupt surge in previously scarce nutrients. These "red tides" or "harmful algal blooms" can result in fish extinctions, human disease from shellfish poisoning, and the extinction of shorebirds and marine mammals.
Because of the consequently low oxygen levels near the Gulf's bottom, most marine species cannot exist there. Fish, shrimp, and crabs frequently leave the region by swimming away, but creatures that cannot swim or leave are distressed or killed by the low oxygen. Every summer, there is a dead zone in the Gulf of Mexico.

as ambient temperature decreases, metabolic rate in an ectotherm decreases to maintain body temperature.
The order is False.
In Ectotherms, decrease in ambient temperature causes body temperature to decrease, that causes a decrease in Metabolic rate.
What are ectotherms?Any animal that is considered to have cold blood, or whose ability to regulate body temperature depends on environmental factors like sunlight or a heated rock surface. Ectotherms are organisms whose internal physiological sources of heat play a small or almost insignificant role in regulating body temperature. Such organisms depend on heat sources in their surroundings, which enables them to have incredibly efficient metabolic rates. Fish, amphibians, reptiles, and invertebrates are all ectotherms. Endothermic organisms include human. This suggests that humans are less dependent on the external environmental temperature than ectothermic (poikilothermic) animals like fish and reptiles.Learn more about the Ectotherms with the help of the given link:

What would be a correct unit of measurement for velocity?
Meters/second
North Meters / second
North
hours
Answer:
meter per second
Therefore, velocity is expressed in meters/second or m/s. The SI unit of velocity is meter per second (m/s). Alternatively, the velocity magnitude can also be expressed in centimeters per second (cm/s).
Explanation:
Brainliest please?
A correct unit of measurement for velocity is meters/second. Velocity is the rate at which an object changes its position in a specific direction over time.
The standard unit for measuring velocity in the International System of Units (SI) is meters per second (m/s). It represents the distance traveled in meters divided by the time taken in seconds, indicating both the magnitude and direction of the object's motion.
The options "North Meters/second" and "North" are not appropriate units of measurement for velocity. "North" represents a direction but does not provide information about the speed or magnitude of the object's motion. Additionally, "hours" is a unit of time and not directly related to measuring velocity.
Therefore, the correct unit of measurement for velocity is meters/second.

People who are lactose intolerant lack the lactase enzyme. They often experience digestive problems when they eat dairy products. Do the results of demetri’s experience support this scenario? Explain your response
Answer:
Yes, the results of demetri's experience support this scenario.
Explanation:
A milk allergy is an immune response which involves the production of antibodies specific to substances in milk, such as casein. Lactose intolerance does not involve the immune system but is the result of an inability to produce the enzyme lactase. People with milk allergies suffer from different symptoms than people who are lactose intolerant. The symptoms of a milk allergy include hives, wheezing, and vomiting, whereas the symptoms of lactose intolerance are gastrointestinal distress, including gas and diarrhea.

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.

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.

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.
