Which of the following organisms are considered to be plant-like protists?A. bacteria
B. algae
C. plasmodia
D. paramecia

Answers

b. algae.
Algae produces energy through photosynthesis just like plants, but it isn't a plant.

Plant cells undergo photosynthesis to produce glucose, a usable form of chemical energy. The energy produced by plants becomes the base of an energy pyramid. Given the situation seen above, what reactant is missing in order for photosynthesis to occurA) water 
B) ozone 
C) chlorophyll 
D) radiant energy

Answers

Water is the key reactant missing, Radiant energy is not needed as plants can produce energy/glucose in both light dependent and light independent reactions, Chlorophyll Is the organelle what is used to produce the atp 
Photosynthesis: water + carbon dioxide + Sunlight = Glucose + oxygen.

Why do cells undergoing mitosis require one set of divisions, whereas those undergoing meiosis require two sets of divisions? what is the end result of meiosis?

Answers

Mitosis, you see, is somatic (body) cell division, and the DNA in the nucleus during Interphase can replicate by doubling the chromosomes before the actual mitosis or cell division process of splitting into TWO identical cells (and they function the same with the same number of identocal chromosomes too! So they are called Diploid cells with 46 chromosomes!)

Meiosis is sperm/egg division and must divide twice to produce FOUR sperm or egg cells. Sperm goes through I- PMAT just like mitosis, but goes through PMAT again after that! They create four Haploid gametes (sex cells) with 23 chromosomes so that when an egg and a sperm unite in sexual reproduction, the zygote (fertilized egg) will have exactly 46 chromosomes like the normal number of chromosomes in a somatic cell. ^^

The body's ability to maintain a relatively constant internal environment is called homeostasis. This stability can be challenged by:(Select all that apply)
A. reduced water or food intake
B. infectious organisms
C. elevated or depressed blood pH
D. extreme temperatures.

Answers

Homeostasis is the body's ability to maintain a constant internal environment. This stability can be challenged by reduced water and food intake and an elevated or depressed blood pH.

Final answer:

Homeostasis, the body's ability to maintain internal balance, can be challenged by reduced food or water intake, infectious organisms, changes in blood pH, and extreme temperatures. These challenges can disrupt the body's normal functions and cause varying health impacts.

Explanation:

The body's ability to maintain a relatively constant internal environment, called homeostasis, can indeed be challenged by various factors. Reduced water or food intake can alter the balance of nutrients and hydration in the body, potentially leading to dehydration or malnutrition. Similarly, infectious organisms such as bacteria, viruses, or parasites can disrupt homeostasis by causing disease.

Elevated or depressed blood pH, which refers to the acidity or alkalinity of the blood, can disrupt bodily functions if it falls outside of a certain range. Finally, extreme temperatures can challenge body's ability to regulate its own temperature, potentially leading to conditions like hypothermia or heat stroke.
