Name the type of circulatory system found in the phylum Arthropoda

Answers

Answer:

Open circulatory system

Explanation:

An open circulatory system, found in arthropods, pumps blood into a cavity called a hemocoel where it surrounds the organs and then returns to the heart(s) through ostia (openings). The blood found in arthropods, a mix of blood and interstitial fluid, is called hemolymph.Arthropods have an open circulatory system. In an open circulatory system, blood isn't transported in the body through veins and arteries; it flows freely within body cavities and makes direct contact with the organism's internal tissues and organs! Most arthropods that live in the water have gills.

Compare the plant cell system vs the plant organ system. Plant Cell. Plant Organ System. 1. Nucleus. 1. Shoot system (Leaves, buds, stems, flowers, fruit) 2. Chloroplasts. 2. Root system 3. Cell wall 4. Mitochondria 5. Large vacuole 6. Cytoplasm

Answers

Answer:

Comparison is given below.

Explanation:

Nucleus controls and regulates the activities of the cell such as growth. Shoot system is the part of plant body present above the soil. The main function of shoot system is the production of food in the process of photosynthesis. Chloroplast is the where photosynthesis occurs. Root system is present inside the soil that is responsible for the absorption of water and nutrients from the soil. Cell wall is the boundary of cell whereas mitochondria is the powerhouse of the cell because energy for the cell is produced here. Large vacuole is the organelle that is responsible for the storage and waste disposal. Cytoplasm is the liquid medium in which the organelles are present in or over the surface.

humans developed antibiotics to fight bacterial infections however some antibiotics are no longer effective in killing the bacteria than once killed how does the theory of evolution explain this antibiotic mutated the bacteria which allowed resistance develop

Answers

Answer:

Changes in genetic makeup occurs with the passage of time.

Explanation:

Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.

Give an example of how a living part if the ecosystem depends on the non-living parts?

Answers

Answer:

The living things in an ecosystem are interdependent. This means that living things depend on their interactions with each other and also nonliving things for survival. For example, a tree depends on sunlight for energy and food. A snail depends on plants for food.

Answer:

Some examples of important nonliving things in an ecosystem are sunlight, temperature, water, air, wind, rocks, and soil. Living things grow, change, produce waste, reproduce, and die. Some examples of living things are organisms such as plants, animals, fungi, and bacteria.

Using the following words, explain the difference between
DNA and RNA.

Nucleus, uracil, double helix

Answers

RNA is single-stranded while DNA is double-stranded.
RNA contains uracil while DNA contains thymine.
RNA has the sugar ribose while DNA has the sugar deoxyribose.
DNA has four nitrogen bases, one of them being thymine. For RNA, instead of having thymine, it has uracil. DNA is a double stranded (also known as double helix) and RNA is single stranded. This explains why RNA can leave the nucleus and DNA can’t.

PLEASE HELP!!!! You discover a new protist species. It has chloro-
plasts and vacuoles and moves using a flagellum.
How would you classify the way that it gets energy?
Is it an autotroph, heterotroph, or both? Explain
your answer.

Answers

Answer:

Autotroph

Explanation:

An autotrophic organism is any organism that is capable of synthesizing its own food either by using sunlight (photosynthesis) as an energy source or chemicals (chemosynthesis). An organism capable of photosynthesis must possess CHLOROPLAST (CHLOROPHYLL), which is responsible for capturing sunlight in the cell and also harbors the photosynthetic process.

According to this question, a newly discovered protist is said to have chloroplasts and vacuoles and moves using a flagellum. Due to the fact that this protist possess CHLOROPLAST organelle, it means it can perform photosynthesis, which is one of the ways an autotrophic organism synthesizes it's food. Hence, the organism is AUTOTROPHIC.
