the small intestine is at the same level of organization as which of the following heart, connective tissue, digestive system, or epithelial cell?
Answer:
Heart
Explanation:
They are both organs, everything else is too big or too small.
The small intestine is at the same level of organization as the heart. The correct option is a.
What is the level of organization?The body is divided into different levels of the organization. These levels of organization are cellular level, tissue level, organ, organ system, and organism.
At the cellular level, the cell is the base unit of life. At the tissue level, the cells joined and compose tissues. At the organs level, tissues are joined to make organs, and many organs form an organism.
The small intestine and heart are organs, so they come in the same level of organization. The organ. The digestive system comes from the organs system and epithelial cell comes at the cellular levels. Connective tissue comes under tissue level.
Thus, the correct option is a. heart.

What could be some weaknesses with using a test cross to determine Fred’s genotype?
Answer:
The disadvantage of this test and it's weakness is if there is a genetic trait with complete domination, then the plant with the recessive characteristic has to be acquired.
Explanation:
To determine a genotype is not that easy and effortless because you can't see the genes of one organism if you just look at it.
Explain how oxygen gets to your cells and waste gets out through the circulatory and respiratory systems.
Answer:
The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it.

explain the role of diaphragm in the process of breathing
Answer:
The diaphragm muscle contacts and relaxes to force the intake and expulsion of air from the lungs.
Explanation:
The diaphragm is a large, dome-shaped skeletal muscle. It is very thin, and is located at the base of the chest just above the abdomen. It plays a very important role during respiration or breathing by forcing the intake and expulsion of air from the lungs.
During inhalation, this muscle contracts, and flattens- in the process, a vacuum is created, effectively pulling air into the space. In exhalation the muscle relaxes, and is no longer flattened, this reduces the volume of the region, forcing air out of the lungs. These contractions occur rhythmically and continuously.

postcranial changes in hominins that indicate bipedal locomotion include group of answer choices shortening and broadening of the ilium of the pelvic girdle increased length of arms relative to legs feet with opposable big toes for grasping all of these answers are correct
Option A: Postcranial changes in hominins that indicate bipedal locomotion include shortening and broadening of the ilium of the pelvic girdle.
Around 3 million years ago, bipedal locomotion in early hominins turned to be more effective. This adaption made the hominins more stable to hold their weight and walk upright. It also helped them to see longer distances in the green forests areas. They could take the advantage of hunting their food or protecting them from harmful predators. Adapting bipedal location expended lesser energy, thus allowing hominins to walk longer distances.
Over many generations now, bipedal location turned out to develop stronger and longer legs and feet so as to allow running and holding more weights. Additionally, the arms turned to be more adapted to hold the heavier things efficiently and to carry their newborns effectively.
Owing all these changes, adaption made to this kind of locomotion include shortening and broadening of the ilium of the pelvic girdle and developed a bowl-shape structure.
Thus, option A is the correct answer.

Discuss the benefits and costs of different methods of irrigation, both to the farmer and the watershed
The fundamental goal of irrigation, which is to augment water provided by rainfall in order to increase crop yields and/or crop quality, hasn't changed much through time, despite substantial technological advancements.
Crop irrigation is an agricultural practise that has been used for many centuries in human history. The various forms of irrigation include

Flooding or furrow irrigation involves completely soaking the soil surface and moving the water by gravity through the area. Nutrients, hydrogen, and oxygen are distributed to your roots more consistently with irrigation. High-pressure sprinklers placed in the field are used to water crops; they can be stationary or moved by manually.

False
Explanation:
S -waves are not the first set of waves to arrive at a seismic station after an earthquake event has occurred
These waves are the second set of waves to be picked up at a seismic recording station.
S - waves are shear or secondary waves. They are the second to arrive at a seismic station. P - waves are the fastest waves with the greatest velocity. They are the first set of waves to arrive at a seismic station. P - waves are simply longitudinal waves and they are the fastest elastic waves.Answer:

How Cytoplasmic soup is formed?
Answer:
It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm.
Explanation:
Hope it helps
Mark as brainliest:D
Answer:
The cytoplasm (also known as cytosol) is the protoplasm of a cell outside the cell nucleus. It is the jelly-like material plus the organelles outside the nucleus, and inside the cell membrane.
Many important functions of a cell take place in organelles, which are like bits of machinery for doing many jobs. The cytoplasm is highly structured: it is not some kind of soup, even though it is made out of 75–80% water.
The cytosol contains a complex mixture of cytoskeleton filaments, including the endoplasmic reticulum and the Golgi apparatus. It includes dissolved molecules, and water that fills much of the cell. Due to this network of fibres, membranes and the many dissolved macromolecules such as proteins, the cytosol does not act like a simple liquid. The main function of the cytoplasm is to hold the organelles in place

Brown-eyed alma has a blue-eyed mother and a brown-eyed father. In this case, her brown eyes were determined by a _____ allele.
In this instance, a dominant allele was responsible for her brown eyes.
Dominant alleles: what are they?A dominant allele is a gene variant that, even in the presence of other alleles, will cause a certain phenotype.Usually, a dominant allele codes for a protein that functions. One copy of the allele generates enough enzyme for a cell to have an abundance of a certain product, which is why the allele is dominant.What makes a gene a dominant allele?Because it hides the recessive trait and manifests in the phenotype of a heterozygous creature, a dominant allele is referred to as dominant. It takes just one allele to express the characteristic.learn more about dominant allele here

The complete diagram is shown below in the image representing the stages of meiosis.
Mitosis as well as meiosis are both types of division of the nucleus in the eukaryotic cells. The complete diagram shows that Meiosis comprises of two nuclear divisions which lead to the formation of four nuclei which are generally divided resulting in the creation of four new haploid cells.
The nuclei that are formed by the process of meiosis are not genetically identical unlike mitosis. During Meiosis I, the synapsis of homologous chromosomes occurs, chiasmata formation and crossing over takes place. The sister chromatids also align along the Metaphase plate in tetrads.

What are the dangers, consequences of bad / pseudoscience science
articles.
Meiosis is a process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell. Meiosis usually involves two distinct divisions called meiosis I and meiosis II. By the end of meiosis, a single diploid cell has produced four haploid cells.
After interphase I, the cell begins to divide, and the chromosomes pair up. In prophase 1 of meiosis, each replicated chromosome pairs with its corresponding homologous chromosome. This pairing forms a structure called a tetrad, which contains four chromatids. As the chromosomes pair, they sometimes undergo a process called crossing-over.
Which is a true statement of crossing-over?
A. Homologous chromosomes move to opposite ends of dividing cells
B. During crossing-over, bits and pieces of the homologous chromosomes are exchanged
C. The DNA of the diploid cell is copied
D. Crossing over decreases genetic diversity
