How did early land animals differ from those common today?
Answer:
Early land animals had both lungs AND gills, and their bodies consisted of few hard parts. Meaning they lacked things like an exoskeleton for instance. Animals today have either lungs OR gills and many have protecting hard parts of their bodies.

Answer:
brainliest plzzzzzzzzzzzzzzzzzz
Explanation:
1.Stem cells are special human cells that are able to develop into many different cell types. This can range from muscle cells to brain cells
2. Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.
3.Gene therapy does have risks and limitations. The viruses and other agents used to deliver the "good" genes can affect more than the cells for which they're intended. If a gene is added to DNA, it could be put in the wrong place, which could potentially cause cancer or other damage.
4.Clinical trials of gene therapy in people have shown some success in treating certain diseases, such as: Severe combined immune deficiency. Hemophilia. Blindness caused by retinitis pigmentosa.

Engineered Natural Killer Cells against Hodgkin's Lymphoma. Pectic Acid-based Corning Dissolvable Microcarriers for Cell Therapies. Development of Cell Expansion Systems for Gene-edited Blood and Immune Cells. Microsoft's AI Tool for Fine Tuning CRISPR.I give out brainlist

Sex hormones, secreted in greater amounts in females than males, and
contributes to female sex characteristics *
Answer:
Your answers are probably estrogen and oxytocin.
The sex hormone that is secreted in greater amounts in female and contribute to female sex characteristics is estrogen.
Sex hormones are those hormones that are secreted by both male and female which are used for sexual development and reproduction.
Example of sex hormones include estrogen
This sex hormone is secreted both in female and in male but in greater amounts for females.
This is because males secrete more of the sex hormone, testosterone
The estrogen contributes to female sex characteristics through the following ways:
it contributes to the development of the reproductive system,Development of breast and public hairs. Estrogen contributes to cognitive health , bone health, the function of the cardiovascular system , and other essential bodily processes.
Therefore The sex hormone that is secreted in greater amounts in female and contribute to female sex characteristics is estrogen.

Which might be considered a limiting factor to the amount fish in a lake *
A)Amount of squirrels in the environment
B)Amount of water in the lake
C)Temperature of the lake
D)Choice 2 and 3
Answer:
D). Choice 2 and 3
Explanation:
Given the options above, the limiting factors are both the "Amount of water in the lake" and the "Temperature of the lake"
This is because the amount of water in the lake can only carry as much of the number of fishes as possible it can contain or sustain. This implies that the higher the water content in the lake the higher the number of fishes it can contain and vice versa.
Also, the temperature of the lake is a limiting factor because the temperature of the lake supports the light penetration to the fishes in the water. Should the temperature increases beyond the highest level the water can support, the fishes will die.

Why would an enzyme that is effective with one reaction have no effect on another reaction?
Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules.Answer:

Draw a portion of a plasma membrane of a cell and label the cytoplasmic and extracellular surface. Place the following four proteins in the membrane: a) peripheral membrane protein (cytoplasmic exposure), b) integral protein (transmembrane exposure), c) integral protein (extracellular exposure) and d) peripheral protein (extracellular exposure)
Answer:
You will find the draw in the attached files.
Explanation:
Integral proteins: Proteins that are permanently encrusted in the membrane. These molecules might be classified into three groups: transmembrane proteins, those encrusted in one of the monolayers, and those that only join a membrane protein.Transmembrane proteins cross the membrane from side to side. They have three domains in their monoacidic sequences: an extracellular hydrophilic domain, an intracellular hydrophilic domain, and an interior hydrophobic domain. The aminoacidic chain of these molecules might cross the membrane just once or many times, depending on the protein. Transmembrane proteins accomplish many functions, such as substance adhesion, ions interchange, molecules transport, communication, among others.
Proteins encrusted in one of the monolayers do not cross the membrane. Their monoacidic sequences are integrated with only one of the monolayer lipids, hence they have an intramembrane domain and only one extramembrane domain, which might be either cytosolic or extracellular, depending on their position in the membrane.
Peripheral membrane protein: Proteins that are not encrusted in the membrane, but just united to the internal or external membrane surfaces, and they can easily separate from it. Opposite to integral proteins, peripheral ones are not in a permanent association with the membrane. Instead, they are just temporally united to the membrane. This makes them useful for cellular communication. They can be attached to integral proteins and little portions of the lipidic bilayer.In an unusually cold winter, a population of rabbits would be affected in

how does time affect the physical weathering of a rock?
A- rock weathers the most when first exposed, then more slowly
B- the longer the rock has been exposed, the more it has weathered
C- over time, the rock will become flat, slowing the rate of physical weathering
D- time does not affect physical weathering, only chemical weathering
Answer:
D
Explanation:
Time can't do much to a rock, but chemical weathering is more effective
The time affect the physical weathering of a rock as time does not affect physical weathering, only chemical weathering and time can't do much to a rock, but chemical weathering is more effective. Thus, option D is correct.
What is the sedimentary rocks?Sedimentary rocks are near the surface so the only one that works for that is sedimentary rocks are formed with water too, it weathers away at the rocks to form little sediments and metamorphic rocks are in the earths interior and sedimentary are at the exterior, metamorphic rocks are formed through extreme heat and pressure meaning its near the earths interior.
Igneous rocks has been called the magmatic, are all rocks that are formed by the solidification of magma. However, igneous rocks are classified into two groups. First are the plutonic or intrusive igneous rocks that are the result of the solidification of magma within the lithosphere. Secondly, there are the volcanic or extrusive igneous rocks that are the result of the cooling of magma that occurs at the surface or a shallow depth.
Therefore, The time affect the physical weathering of a rock as time does not affect physical weathering, only chemical weathering and time can't do much to a rock, but chemical weathering is more effective. Thus, option D is correct.
