How do you know something is dead
Is this without equipment?
Depending on what organism you are talking about, animals that can be seen with the unaided eye you can tell that they are dead by studying their bodily movements such as the rise or falling of their chest.
Plants with the unaided eye, the best indicator is to take a branch or piece off and study the insides color, if it is green then mostly likely they are alive.
Now microscopic organisms are harder to say, it depends on what you are referring to.
Models can be used to describe
Answer:
Depending on what is shown, it can give a large scale idea or detail of many small or microphic items.
Explanation:
Answer:
In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations.

A scientist conducted a study of an organism and found that its body cells contained 40 chromosomes. While conducting her observations, the scientist noticed that the cells were undergoing cell division. What difference would the scientist expect to observe between the body cells and the sex cells of the organism as they underwent cell division?
Body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.
Body cells divide by mitosis for sexual reproduction, while sex cells divide by meiosis for the growth and repair of cells.
Body cells divide by meiosis for the growth and repair of cells, while sex cells divide by mitosis for sexual reproduction.
Body cells divide by meiosis for sexual reproduction, while sex cells divide by mitosis for the growth and repair of cells.
Answer:
The difference that the scientist would expect to see between body cells and sex cells with respect to cell division is that body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.
Explanation:
The behavior of the different cell types with respect to their division depends on the functions that each type has.
Somatic cells are those that define the structure and function of the organism, forming tissues by binding together. The process of mitotic division —to obtain from an original cell two identical daughter cells— is important for the growth, development and repair of an individual's tissues.Sex cells or gametes have half of the chromosomal charge —they divide by meiosis, a reductive cell division— and are involved in the process of sexual reproduction.The characteristics described for each cell type explain why the other options are not correct.
Answer:
Body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.

Removing a specific group of trees within a small area over a long period of time is
a. clearcutting
b. seed tree cutting
C. group selection
d. single tree selection
Answer:
C. group
Explanation:
Removing a specific group of trees within a small area over a long period of time is group selection. The correct option is C.
What is group selection?A quantitative definition of group selection is when the average group fitness is greater or less than the mean of the fitness values of the individual members.
Another definition of group selection is when features evolve in accordance with the fitness (survival and reproductive success) of groups.
The conclusion was that although group selection is theoretically feasible, in practice it almost always favors one group over another.
Group selection is the long-term removal of a certain group of trees in a constrained region. In a clearcut, all the trees in a specific region are taken out at once.
The removal of shelterwood cutting clears an area's also clears land cleared for shelterwood cutting, which also involves cutting downing shelterwood cutting, but it is a completes a method of clearing
Thus, the correct option is C.

There are two continents with an ocean between them. Today, the continents have very different plants and animals on them. However, a geologist found fossils of the same type of organism on both continents. Millions of years ago, when this type of organism was alive, we know it lived in only one place. The geologist is using the fossils as evidence to argue that the two continents used to be touching. How could the continents have gotten so far apart, and how long did it take for this to happen?
Answer:
The continents could have gotten so far because of plate tectonic movement. We know that the plates are always moving so if these plates were very active then it would have caused supercontinent pangea to drift apart. This process must have taken more than a million years to happen.

of mitotic cell division?
23 pairs of chromosomes will be found in each of the two new cells formed as a result of mitotic cell division.
WHAT IS MITOSIS:
Mitosis is a kind of cell division that results in the formation of two daughter cells with the same number of chromosomes as the parent cell. Mitosis is used for growth and tissue repair in living organisms. In mitosis, a parent cell divides into two new daughter cells, however, each cell possess the same number of chromosomes as the parent. In a somatic human cell, there are 23 pairs of chromosomes (46 chromosomes). If this cell undergoes mitotic division, then, there will be 23 pairs of chromosomes in each cell formed.Learn more: https://brainly.com/question/3327479?referrer=searchResults

habit=brushing your hair
reflex=eye blinking
I hope this helped and was explained better
The behavior type of response with the corresponding action is instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.
What is the corresponding action?The brain control action is regulated by the body some are involuntary and others are voluntary it creates a rhythm in our body to make the system regulate.
Migration is instinct but putting puzzle is a trial and error condition, when the eye is blinked is a reflex action, and crushing your hair is a habit while getting hungry before lunchtime is a conditional response.
All the action of the body is controlled by the body's action some signals are sent to the body to regulate every action to control conditional response or habit.
Therefore instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.

On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color eyes will the offspring have?
Answer:
75% red, 25% other color (brown?)
Explanation:
A cross between two heterozygous red eye flies (Rr x Rr)
R r
R RR Rr
r Rr rr
The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.
Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)
