Answer:

I'm sure the correct answer is B. over time, more members will have useful markings.

Explanation:

If these markings are a chosen trait in the snakes offspring, the number of snakes with these markings will grow.

However, if the trait is not a dominant one then it is less likely to show up in offspring and could be at risk of going extinct.

Do the shortest duration of insolation and the minimum temperature occur in the same month?
zloy xaker [14]

Answer:

Yes, the shortest duration of insolation and the minimum temperature occur in the same month.

Explanation:

  • The shortest duration of insolation occurs in month of December and sometime the minimum temperature may also occur in the month.
  • The shortest day of the year is December 21 and insolation at that day is also shortest of the year.
  • If the sun is out for a longer time the temperature will be much greater, because the sun is shining for a greater amount of time.

Explain how weathering, erosion, and subduction/volcanic activity help move or transfer carbon around the
chubhunter [2.5K]

Answer:

Plankton use carbon to make carbonate (CO3) shells in the ocean. The shells sink and accumulate into layers of sediments and eventually rocks. Rocks are pushed deep into the earth and melt at subduction zones, dissolving the carbon. Volcanic eruptions release carbon dioxide into the atmosphere.

Which organelle carries substances to other parts of the cell?
STALIN [3.7K]
The answer will be Endoplasmic Reticulum (ER).

It is a kind of channel that carries substances, such as proteins, oil droplets, water, to other parts of the cell.

Well, to make it easier, endoplasmic reticulum is actually a fancy way of saying "cellular highway". I will explain to you why. I always like to study BIOLOGY relating our activities and our stuff. 

Okay, let's push aside cells. Let's think of us, humans. We can't stay in one place, we gotta moving all around the city. What do we use for moving around the city: either roads or sidewalks or footpaths.

Just like that, a cell also has a medium or road or a channel where all the substances can move around the cell. Well, its ER! So, from now on, everytime you are struggling with this difficult, L O N G word, just replace it with "cellular highway". The ER is like a water pipe, too. Water flows through it. Here, cellur substances flow through it. The ER is connected to the nucleus.

SUMMARY:

1# ER aka Endoplasmic Reticulum is a kind of channel that carries substances, such as proteins, oil droplets, water, to other parts of the cell.

2# 
Try thinking it easy: replace it with "cellular highway".

3# 
It is much like the roads or sidewalks, we walk on.

Give 5 examples each of mutualism, communalism, and parasitism.
lys-0071 [83]
<span>1. Mutualism is a type of relationship that can be seen between two individuals of two different species to obtain benefits for both of individuals.

Examples : Coral polyps and zooxanthellae
                   bee and flower
                   Lichens
                   Rhizobium and root nodules
                   Ungulates and bacteria which live in their intestines

</span><span>2. Commensalism (this is the correct word) is a type of relationship between two organisms which belonged to two different species that one individual obtains benefits while other doesn't have any harm or benefit.

Examples : Remora and sharks
                   Orchids and trees
                   Pseudoscorpions and Beetles
                   Cattle Egrets and Livestock
                   hermit crab and sea anemone
</span>
3. Parasitism is a relationship between two organisms of two different species where one individual (parasite) gets benefits by harming other individual (host).
 
Examples : <em>Cuscuta</em> (parasite)<span> and angiosperms (host)
                    Parasitic viruses (parasite) and human (host)
                    Tape worms (parasite) and pigs (host)
                    Flukes (parasite) and human (host)
                    Parasitic bacteria (parasite) and human (host)</span>
