what cell type would you expect to increase if a person were infected with a relatively large parasite such as a tapeworm?
the type of cell which would increase if a person were infected with a relatively large parasite such as a tapeworm is Eosinophils.
When your body produces an abnormally high number of eosinophils, the condition is called eosinophilia. One of the many white blood cells that help your immune system is an eosinophil.
The most common cause of persistent eosinophilia is parasitic helminth infections like tapeworms. Trichinosis, ascariasis, filariasis, and paragonimiasis are some other infections caused by helminths that have life cycles that include tissue migratory phases. These infections cause persistently elevated eosinophilia in the blood and tissues of the host.

1) what are rules about matter we should follow when investigating and explaining how plants grow and function?
2) what are rules about energy we should follow when investigating and explaining how plants grow, move, and function?
1.) Just as matter is made up of particles that works together to lead to the successful functionality of the system, the plant is made up of cells and tissues that function together to lead to its growth and development.
2.) Just as energy is neither created nor destroyed but can be transformed from one state to another, the energy from sunlight is being transformed to chemical energy which is being used by plants to grow, move and function.
What is matter?Matter is defined as a substance that is made up of particles that has weight and can occupy space. Matter is also made up of three major states such as solid, liquid and gas.
A plant is considered to be a matter as it is made up of cells and tissues such as the pith, protoxylem, xylem, phloem, sclerenchyma, chloroplast and cortex. These plant tissue cells obey the rules of matter as they function together to bring about the effective growth and development of the plant.

engineered cell.
Answer:
Explanation:
A small piece of circular DNA called a plasmid is extracted from the bacteria or yeast cell.A small section is then cut out of the circular plasmid by restriction enzymes, ‘molecular scissors’.The gene for human insulin is inserted into the gap in the plasmid. This plasmid is now genetically modified.The genetically modified plasmid is introduced into a new bacteria or yeast cell.This cell then divides rapidly and starts making insulin.To create large amounts of the cells, the genetically modified bacteria or yeast are grown in large fermentation vessels that contain all the nutrients they need. The more the cells divide, the more insulin is produced.When fermentation is complete, the mixture is filtered to release the insulin.The insulin is then purified and packaged into bottles and insulin pens for distribution to patients with diabetes.The DNA of an animal's somatic cell is transferred into an egg cell that has had its nucleus and DNA removed in order to create a clone. With the same genes as the cell donor, the egg develops into an embryo. The embryo is then placed inside the uterus of an adult female to develop.
What is DNA ?A polymer made of two polynucleotide chains that coil around one another to form a double helix is called deoxyribonucleic acid. All known organisms and many viruses have genetic information in the polymer that is necessary for their development, operation, growth, and reproduction. Nucleic acids include DNA and ribonucleic acid.
The process of genetic engineering consists of three main phases. These include (1) isolating DNA fragments from a donor organism, (2) integrating an isolated donor DNA fragment into the genome of the vector, and (3) allowing the recombinant vector to develop in the proper host.
Selection, mutagenesis, conjugation, and protoplasm fusion are examples of conventional genetic modification techniques that have been used, particularly for microbial starter cultures. The latter is comparable to somatic hybridization in plant systems.

in skeletal muscle fibers, each myosin head binds to a group of answer choices tropomyosin. myosin tail. g actin. titin. troponin complex.
Each myosin head needs to bind an ATP molecule for this release. The myosin head is released from the actin by ATP attaching to it.
The head "recocks" (the recovery stroke) as a result of the ATPase hydrolyzing the ATP into ADP and a phosphate group, preparing it for the following power stroke.
Actin and myosin do not shorten as skeletal muscle fibers contract, which is explained by the sliding filament hypothesis of muscle contraction. Instead, they pass one another by.
The separation of myosin heads from actin requires ATP. Also, observe that the H zone and the light I band appear to narrow with sarcomere contraction, but the dark A band does not.

the phosphorus is a limiting factor for algae growth? Why or why not?
Answer:
Phosphorus can be a limiting factor for algae growth
Explanation:
Phosphorus and nitrogen are essential for algae growth. An increase in these nutrients causes the growth of algae to rapidly increase. This can be harmful to other plants and organisms living in the pond/sea, as the rapid increase in algae blocks sunlight from reaching the bottom of the pond. This kills plants that require sunlight to photosynthesise and saprobiotic bacteria decomposes this matter, by using oxygen. In turn this depletes oxygen available for any surviving plants and other fish species living in the area, causing them to die as they need oxygen to respire.
This process is called eutrophication where the increase in Phosphorus and nitrogen leading to a dense growth in plant matter

creatine kinase : donates one of its phosphate groups to adp.
Explain the creatine kinase ?The enzyme (EC 2.7.3.2) creatine kinase (CK), sometimes referred to as creatine phosphokinase (CPK) or phosphocreatine kinase, is expressed by a variety of organs and cell types. Using adenosine triphosphate (ATP) and creatine, CK converts the latter into phosphocreatine (PCr) and adenosine diphosphate (ADP). Because of the reversibility of this CK enzyme reaction, ATP can be produced from PCr and ADP.PCr serves as an energy reservoir for the quick buffering and regeneration of ATP in situ, as well as for intracellular energy transport by the PCr shuttle or circuit, in tissues and cells that rapidly consume ATP, particularly skeletal muscle, but also brain, photoreceptor cells of the retina, hair cells of the inner ear, spermatozoa, and smooth muscle.Learn more about creatine kinase refer to :
