Answer and Explanation:
Even though Northern seals display a dark brown skin color, their pups are born with a fluffy white coat. This allows them to camouflage with the environment as they are unable to swim like the adults, keeping them away or hidden from predators.
Once they are around three weeks old, they start to lose this layer and begin to look like the "normal" seals.
Moreover, due the predominant climate in which they live, the color of the fur depends on genes and, therefore, enzymes. These enzymes are present during cold temperatures and, due to the warm conditions of the womb, these enzymes are denatured. After the seal pup is born, its cells produce a higher amount of enzymes to adjust to the temperature of their habitat and stays with the brown color to maintain homeostasis.
in Earth's early conditions?
Answer:
Earth’s primitive atmosphere allowed for more of the Sun’s rays to reach the bacteria. In addition, the oceans and atmosphere were richer in carbon dioxide than they are today. Both of these factors helped green bacteria survive in Earth’s early conditions.
Explanation:
plato
Explanation:
The early atmosphere was mainly made of carbon dioxide and methane.
These early bacteria were able to harness the energy of the sun to make their own food by reducing carbon dioxide into glucose. Due to the abundance of carbon dioxide and sunlight, these organisms were able to thrive, unlike heterotrophs bacteria that depended on other organisms for food.
Photosynthetic bacteria were able to thrive so well that their abundance caused a change in the composition of the atmosphere in what is referred to as the Great Oxygenation Event. They evolved oxygen during photosynthesis hence causing the significant composition of oxygen in the air today.

B) the stem because It holds the organism upright
C) the roots because they absorb water and nutrients
D) the seed because it allows the fungi to reproduce
Answer:
The correct answer is option C, the roots because they absorb water and nutrients
Explanation:
A hypha is like tubular structure which enable a fungi to move and also helps them in absorbing food and nutrition required by them from their surroundings. A root in a plant system also absorbs essential nutrients from the soil for the plant growth and development. Thus the function of both the root and hypha is more likely similar.
C) the roots because they absorb water and nutrients.
A.A tendon joins a bone to a bone; a ligament joins a muscle to a bone.
B.A tendon joins a muscle to a bone; a ligament joins a bone to a bone.
C.A tendon covers a bone; a ligament supplies nutrients to a bone.
D.A tendon supplies nutrients to a bone; a ligament covers a bone.
A tendon is different from a ligament in that a tendon joins a muscle to a bone; a ligament joins a bone to a bone.
The correct option is B; A tendon joins a muscle to a bone; a ligament joins a bone to a bone.
Ligaments are crisscross-shaped bands that connect bones and support joints. For instance, the anterior cruciate ligament (ACL), which stabilizes the knee joint, connects the thighbone to the shinbone.
Muscle is joined to bone via tendon, which is present at either end of a muscle. The head, neck, feet, and the rest of the body are all covered in tendons. The largest tendon in the body is the Achilles tendon. It joins the heel bone and calf muscle. The rotator cuff tendons aid in the forward and backward shoulder rotation.

chemically combined. What type of substance is it? (SC.8.P.8.9)
element
compound
homogeneous mixture
heterogeneous mixture
Answer: Homogeneous Mixtures are the same throughout, meaning all regions of the mixture have the same properties. An example of a homogeneous mixture is salt that is dissolved in water. Another name for a homogeneous mixture is a solution.
Explanation:
Answer:
The wind erosion is defined as the removal of soil particles from a particular area. This erosion mostly takes place in the region where there is less vegetation cover and less amount of rainfall. Presence of vegetation helps in controlling the rate of wind erosion as the plants acts as a barrier to the wind, thereby not allowing it to carry the soil particles with them. But absence of water and vegetation makes the soil dry and the wind removes these particles easily loosing the fertility of the soil.
The wind generally carry the materials by the method of suspension, in which the extremely lighter materials like silt and clay are transported from one place to another.
This is the reason why wind erosion is rapid in the desert areas compared to the places which are rich in thick vegetation cover.
