d. They are both asymmetrical. Placozoans have endoderm and ectoderm while sponges have no tissue.
Explanation:
Placozoans and sponges are both animals with asymmetrical body plans. They differ in that placozoans are slightly more complex than sponges because placozoans have embryonic tissue layers: endoderm and ectoderm. Sponges have no tissue.
In what type of cell does the cell wall take the place of the cell membrane ?
A. Plant cells
B fungi cells
C. Cell walls never take the place of a cell membrane
Answer:
Cell walls never take the place of a cell membrane
Explanation:
The cell wall has a texture that is tough, flexible, and occasionally hard and is found outside the cell membrane, hence option C is correct.
What is a cell wall?Plant cells' outside layer is called the cell wall. Only plants and some types of bacteria, fungi, and algae have cell walls.
Bacteria, algae, fungi, most plant cells, and certain archaea all have cell walls. A cell wall is a structure that surrounds the plasma membrane or cell membrane in cells that have them.
Cellulose or chitin are the main components of the cell wall, which is a stiff, semi-permeable structure.
Glucans, chitin, and glycoproteins make up the majority of the cell wall, which is a distinctive structure of the fungus.
Therefore, cell walls never take the place of a cell membrane.

Pleaseeee help
Answer:
Differences in temperature or precipitation determine the types of plants that grow in a given area (Figure 1). Generally speaking, height, density, and species diversity decreases from warm, wet climates to cool, dry climates. Raunkiaer (1934) classified plant life forms based on traits that varied with climate.

A student found that 3 grams of ammonia gas formed 3 grams of solid ammonia when the
temperature was lowered enough. Why did the solid ammonia and the ammonia gas have the same
mass?
Answer:
The mass of a substance is constant according to the law of conservation of mass.
Explanation:
According to the law of conservation of mass, matter can never be created or destroyed in a chemical reaction, even though it may undergo change from one physical state to another.
This means that in an isolated or closed system, the mass of matter will always be the same irrespective of the type of change that matter undergoes. This is so because, the mass of a substance is a measure of the quantity of matter in that substance and is constant. The number of particles does not change during a change of state, only their spacing and arrangement. In solid ammonia, the particles are more compact and arranged, whereas in gaseous ammonia, they are more randomly spaced out.

An acentric fragment is one result of crossing-over between a normal chromosome and a chromosome that has undergone what kind of mutation?
Answer:
paracentric inversion
Explanation:
A paracentric inversion happens as a result of a portion of one chromosome , or a packet of genetic information, which is flipped such that there are changes in the order of genetic information. Every of the chromosome has a part that is near the middle which is referred to as a centromere. Paracentric inversions do not include the involvement of the centromere of a chromosome.

Gas exchange involves the transport of two respiratory gases, oxygen and carbon dioxide. Review how each gas is transported between the atmosphere and the cells of your body by completing this exercise.1. required for cellular respiration
2. net diffusion from alveoli to lung capillaries3. sometimes transported as bicarbonate
4. net diffusion from body tissues to blood
5. net diffusion from lung capillaries to alveoli
6. waste product of cellular respiration7. enters alveoli during inhalation
8. transported by hemoglobinA. Oxygen onlyB. Carbon Dioxide OnlyC. Both Oxygen and carbon dioxide
Answer:
When we breathe, we inhale oxygen and we exhale carbon dioxide.
Explanation:
1. For the cellular respiration, the body cells are provided with oxygen during gas exchange in respiration.
2. Oxygen gas diffuses from alveoli to the capillaries in our lungs.
3. Carbon dioxide is always transported in plasma or bounded to the hemoglobin or in some form of bicarbonate.
4. Carbon dioxide gas diffuses from our body tissues to the blood.
5. In our lungs, carbon dioxide gas diffuses from capillaries in to alveoli. Carbon dioxide leaves the body when we exhale.
6. During cellular respiration, we give give out and removes carbon dioxide from our body which is a waste product.
7. When we inhale, both oxygen and carbon dioxide gases enters the alveoli,
8. All the oxygen present in blood is bounded by hemoglobin and it is carried to all the body tissues and body and diffuses from our blood to our body tissues.

Consider a duplex molecule of length 10 Mb that has only one origin of replication located exactly in the middle. If replication proceeds bidirectionally, assuming that the rate of DNA synthesis is 1500 nucleotide pairs per second, the time needed for replication of this molecule is _____ minutes.
Answer:
Approximately 28 minutes.
Explanation:
Given:
Length of a duplex molecule of DNA = 10 mb
= 10 * 10^6 bases
So, it means each DNA has = 5 * 10^6 base pair
rate of DNA synthesis = 1500 nucleotide pairs per sec.
location of replication = at the middle which is 5 * 10^6/2
= At 2.5 * 10^6
solution:
As we know replication of DNA is a bidirectional process so it will synthesize in both directions and the rate is given is 1500 nucleotide per sec so the time required to replicate 2.5 * 10^6 in both directions will be from the formula
time = distane/rate
= 2.5 * 10^6/1500
= 1666.66 seconds
or, 28 minutes aprrox (27.77)
