What can a closed system exchange with its surroundings?
Only energy. Through heat and work transfer, a closed system can exchange energy with its environment. So, the two ways in which energy can cross a system boundary are work and heat.
According to kinetic theory, heat is the energy connected to atoms' and molecules' haphazard movements. A temperature difference between two systems causes a form of energy known as heat to be transferred between them. Energy units for heat are kJ. (or BTU). The rate of heat transfer measures how much heat is transferred per unit of time.
Since heat is a directional (or vector) quantity, it has an amount, a direction, and an action point. Heat Heat transfer into systems is positive, whereas heat transfer out of systems is negative. This means that any heat transfer that makes a system more energetic is positive, and any heat transfer that makes a system less energetic is negative.

how do transcription factors and signaling molecules relate to the concepts of autonomous and conditional specification?
Transcription factors as well as signaling molecules play an important role in autonomous and conditional specification as especially conditional specification is dependent on external influences in the determination of the cell fate.
In autonomous specification if a particular blastomere is first removed from an embryo early which is in its development, then that isolated blastomere will be able to produce the same cells which it would have made if it were not removed from the embryo.

as a cell grows, group of answer choices the relationship between its surface area and volume remains unchanged. its dna becomes converted to rna. its surface area increases to a lesser degree than its volume. its requirement for nutrients increases to a lesser degree than its requirement for oxygen. its volume increases to a lesser degree than its surface area.
As a cell grows, its volume increases to a lesser degree than its surface area.
As a cell grows, it increases in size, which can be described as an increase in both volume and surface area. However, the increase in volume is typically proportional to the cube of the cell's size, while the increase in surface area is proportional to the square of the cell's size. This means that as a cell grows, its surface area increases at a faster rate than its volume. This relationship is important because a cell needs to maintain a balance between its internal volume, which holds its metabolic machinery, and its surface cell grows area, which is necessary for exchange of materials with the environment.

The beginning of the process is when light enters the eye; this light has various wavelengths that correlate to various colours. Cones are specialised retinal cells that are responsible for detecting these wavelengths. We can see a broad variety of colours because there are three separate types of cones, each of which is sensitive to a different range of wavelengths. Different neural circuits in the brain process the cone impulses, enabling humans to recognise varying colours, saturation, and brightness.

what happens to the chromosomes during metaphase? are there two copies or a single copy of each chromosome?
During metaphase of mitosis, the chromosomes line up at the equator of the cell and there two copies of each chromosomes.
There are two copies of each chromosome, also known as sister chromatids, held together at the centromere. The centrosomes, which are located at the poles of the cell, create the mitotic spindle that helps to pull the sister chromatids apart. As the sister chromatids align at the equator, the kinetochores on the centromere attach to the spindle fibers.
As the cell progresses through metaphase, the sister chromatids remain connected until the cell undergoes anaphase. During anaphase, the sister chromatids separate and move towards opposite poles of the cell. This process of separation creates two identical sets of chromosomes, which will be used to create two daughter cells.

Any plane that passes through the center of the body divides it into two equal halves, which is a characteristic of radial symmetry. Echinodermata and the Phylum Porifera both exhibit this kind of symmetry. They are animals with radial symmetry (which is symmetry around a central axis so that the organism can be divided into similar halves by any plane that contains the main axis). Therefore, choice B is right.
Animals that are radially symmetrical have a top and a bottom but no front or rear or obvious left and right sides. These creatures frequently have unlimited range of motion. Comparable species with bilateral symmetry include people, seals, and whales, which typically move forward or backward and have clearly defined front, back, right, and left.

True or False? rna catalysis can be selected in laboratory experiments.
True, RNA catalysis can be chosen in lab experiments.It was unexpected to find catalytic RNA because, at first glance, RNA doesn't seem like it would make a good catalyst.
The discovery nearly thirty years ago that RNA can catalyze reactions with abilities comparable to protein enzymes disproved a core biological tenet that RNA serves only as a simple carrier molecule between DNA and proteins.
The active role of RNA as a biological catalyst is seen in the catalytic core of the ribosome and spliceosome, as well as the self-splicing of group I and group II introns. These discoveries, combined with RNA's inherent ability to function as both an effective information carrier and a useful macromolecule, prompted the concept of an RNA world.

In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent). The egg and sperm that combine during fertilisation must be haploid, or having only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes. Meiosis is a type of cell division that occurs in sexually reproducing organisms and lowers the number of chromosomes in gametes (the sex cells, or egg and sperm). Human body cells, also known as somatic cells, have two sets of chromosomes and are diploid (one from each parent).
