Write a paragraph about competition. Must include 5 sentences at least. Include one sentence about the two animals or plants tha
mafiozo [28]

Answer:

I'm not writing your paragraph for you, but I'll give you some help on it.

Explanation:

2 animals that will compete are ants

they are constantly fighting for new territory

What happens, is that when the attackers come, the scouts for the defenders spray something (I forget what) into the air. This alerts the more heavily armed troops nearby. If the defenders win, the attacks are driven back to their colony. If the attackers win, the ants in the defending colony are either overrun and killed, or they run. If the attackers win, they find all the larvae in the nest and either kill them to stop the line together, or in some cases, eat them.

Hope this helps.

How can bacteriophage dna be spread from cell to cell without causing cell death?
nexus9112 [7]

Answer:

through lysogenic cycle

Explanation:

The bacteriophage attaches itself on the bacterial surface. The DNA strand to be replicated is injected into the bacteria by the bacteriophage. The DNA integrates into the bacterial chromosome and  becomes a pro-phage.

The bacterial cell proceeds to cell division  through budding. The progeny possess the bacteriophage. After complete replication, the virus DNA  detaches from the host genome and enters the lytic cycle. The capsid heads assemble on the surface of bacterial cell to package the fully matured viral DNA . The phage produces lytic enzymes that weaken the cell wall of bacteria cell.

Explain how both the digestive system and the urinary system work to conserve water in the human body.
Ghella [55]
Everything that we eat and drink contains some percentage of water. So, to start, you have to know that the human body has receptors which estimate if we have enough water in our blood and cells in general. From these receptors, the information travels through the neurons to the part of the brain that is responsible for activation of different responses. 

The digestive system is important because in its lower parts, liquids are absorbed and inserted in the bloodstream. Then through the bloodstream, they travel to all parts of the body and are absorbed by cells as needed. When blood passes through the body, it gets to the kidneys where water and electrolytes are filtered, reabsorbed if needed and excreted through the urine. 

Now, if the brain has a signal that the body has a lack of liquids, it activates hormones which influence the bloodstream in both the digestive and the urinary system. In this case, the digestive system will absorb more liquids from food because the hormones will make the blood vessels in the digestive area larger, and on the other hand, we will produce less urine because the kidneys will get an assignment from the brain to filter liquids, but to reabsorb them again as much as possible.
