What condition is needed for water to soak in the ground or percolate

Starting from the sun, create a food chain including at least three organisms. Explain how energy is transferred through the cha

Kryger [21]

Answer:

The food chain showing seven organisms can be drawn as follows:

Plants → grasshoppers → mice → frog → snakes→ eagles → decomposers

The plants are the primary source of food in a food chain or a food web. The animals which feed on plants will be termed as herbivores or primary consumers like the grasshopper. The organisms feeding on primary consumers will be the secondary consumers like mice.

An energy pyramid for three of the organisms can be shown as follows:

mice (10 kilocalories)

↑

Grasshoppers (100 kilocalories)

↑

Plants ( 1000 kilocalories)

As the energy pyramid shows, only about 10% of the energy travels from one trophic level to another.

Predict phenotypes associated with nondisjunction of sex chromosomes.

Mnenie [13.5K]

Answer: The new daughter cells will have an abnormal amount of genetic material. That is called aneuploidy and it is the presence of an abnormal number of chromosomes. Different clinical conditions are the result of this nondisjunction.

Explanation:

Normal cells are diploids, that means they have two copies of each gene, one of each chromosome. So normal cells have two homologous chromosomes, one from each parent.

During anaphase of cell division, each pair of chromosomes is separated by the mitotic spindle. The separated chromosomes are then pulled by the spindle to opposite poles of the cell, and eventually will end up in the new daughter cells.

Nondisjunction is the failure of homologous chromosomes to separate properly during cell division, so it is the miss segregation of them. The new daughter cells will have an abnormal amount of genetic material. <u>Different clinical conditions are the result of this nondisjunction.</u>

Sex chromosomes participates in sex determination of an individual. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY) So nondisjunction of sex chromosomes could be:

XX: one cell with no chromosome and the other cell with two X chromosomes.
XY: one cell with no chromosomes and the other cell with XY chromosomes.

According to which gametes are fused during fertilization, different phenotypes can be given. For example, if a gamete with one chromosome fuses with another gamete with two chromosomes, the result will be an individual with three chromosomes (it could be XXY, or XXX) called trisomy.

Triple X syndrome is characterized by an extra X chromosome in females. Those affected are often taller than average, but most females have a normal sexual development. Klinefelter syndrome is known XXY individuals, and it causes infertility in males, breast growth, less body hair and weaker muscles.

And if a gamete with no chromosome fuses also with another gamete with no chromosome, the result is a nullisomy. But due to the lack of genetic material, the nullisomic gametes are rendered unviable for fertilization.

And if a gamete with no chromosome fuses with another gamete with one chromosome (normal) the result is a monosomy, the presence of only one chromosome from a pair. The result can be an individual who is X or Y. People with Turner syndrome have one X chromosome and it is the only monosomy that is seen in humans because other cases monosomy are lethal.

Any of those examples is called aneuploidy and it is the presence of an abnormal number of chromosomes.

Mt-UcGAN: Multi-task uncertainty-constrained GAN for joint segmentation, quantification and uncertainty estimation of renal tumo

olga nikolaevna [1]

Multi-task uncertainty-constrained GAN(Mt-UcGAN) for joint segmentation, quantification and uncertainty estimation of renal tumors on CT conclude that the integrated segmentation, quantification, and uncertainty estimate of renal tumors were initially proposed using a multi-task uncertainty-constrained generative adversarial network (Mt-UcGAN).

A novel adversarial technique with uncertainty limitations was put forth by us. Results from the experiment show that Mt-UcGAN can help with clinical tumor assessments.

Additionally, it can give medical professionals feedback on the validity of the findings, enabling them to undertake further visual reviews and revisions of the findings to raise the diagnostic accuracy.

The three main procedures for clinical tumor disease diagnosis are segmentation of renal tumor, measurement of tumor indices (i.e., center point coordinates, diameter, circumference, and cross-sectional area), and segmentation uncertainty estimation.

These tasks have, however, only ever been researched separately until now. It is quite difficult to describe two distinct tasks as a single optimization framework since segmentation and quantification tasks have separate optimization types.

In this study, we present a unified framework for the joint segmentation, quantification, and uncertainty estimate of renal malignancies on CT (Mt-UcGAN: Multi-task uncertainty-constrained GAN ).

Which of the following is a use for a weather radar a. forecasting weather b. preventing precipitation c. measuring rainfall d.

Elden [556K]

Correct answer: A). Forecasting weather

A weather radar is an instrument that is used to locate precipitation, calculate its motion and determine the type i.e hail, snow or rain. It sends electromagnetic energy pulse into the atmosphere. If that pulse of energy interacts with something, then it reflects back the energy, which can be sensed by the weather radar.

Nowadays, most radar used are Doppler effect, which has dual polarization, it determines that movement is toward or away from the radar.

Hence, the correct answer would be option A.
