The term ‘Protista’ is derived from the Greek word “protistos”, meaning “the very first“. These organisms are usually unicellular and the cell of these organisms contains a nucleus which is bound to the organelles. Some of them even possess structures that aid locomotion like flagella or cilia.
Scientists speculate that protists form a link between plants, animals and fungi as these three kingdoms diverged from a common protist-like ancestor, billions of years ago. Though this “protists-like” ancestor is a hypothetical organism, we can trace some genes found in modern animals and plants to these ancient organisms

During what process do two haploid nuclei within a heterokaryotic fun.pdfvikasbajajhissar
During what process do two haploid nuclei within a heterokaryotic fungal cell fuse?
Fertilization Gametogenesis Plasmogamy Karyogamy This process does not occur in fungi
Which of the following best describes the role of fungi in an ecosystem? Producers Herbivores
Carnivores Decomposers Autotrophs Which of the following statements comparing fungal and
animal nutrition is/are correct? Select all correct choices. Fungi and animals are both
heterotrophs. Fungi and animals both actively move through the environment in search of food.
Fungi digest and then absorb food, whereas animals absorb and then digest food. Fungi are able
to break down cellulose, whereas animals can\'t break down cellulose. Fungi and animals both
absorb the nutrients that can cross their cell walls. Fungi and animals both ingest their food prior
to digestion.
Solution
Q.4 Ans-C plasmogamy
Plasmogamy is life cycle stage in fungi sexual reproduction. During plasmogamy the cytoplasm
of the 2[two] parent cells are fuses together without a fusion of the nuclei and effectively
bringing 2[two] haploid nuclei near together in same cell, next stage is karyogamy,in this stage
two nuclei fudsed together & undergo meiosis, so that they produce spores. dikaryotic state
comes after the plasmogamy stage, and dikaryotic stage frequently persist for too many
generations,and before fungi undergoes for karyogamy. And lower fungi group plasmogamy is
immediately & usually followed by the karyogam
Q.5 Ans-D decomposer
Fungi play important role in ecosystem in several ways, like-Decomposer- is very important to
decomposition of plant and animal dead organic matter in ecosystem, by using degradative
enzyme to hydrolysis of complex organic matter. It this process Saprophytic fungi play important
role, and decomposition necessary for life, Such as oxygen carbon nitrogen cycles. By the
breaking-down dead organic matter,the fungi release [oxygen carbon nitrogen ] into soil &a
tmosphere.Another role is Mutualistic relationship-for example-Lichen [fungal + algae] algae
provide food for fungi by photosynthesis and fungi absorbed essential nutrient to algae for
complete mutualistic life of liches. Another fungi also grow in plant root, they absorbed nutrient
for plant and in exchange sugars and amino acide fungi take from palnt.
Q.6 Ans
1. correct-Fungi and animals both are heterotrophs because they depend on plant for obtaining
nutrient and energy and oxygen for survival.
2. wrong- only animal can move actively not fungi because in fungi they using hyphae or
mycelium to reach to food, that’s way fungi is in different category in domain
3.wrong statement-, in animal mode of nutrient is ingestion than digestion than absorb through
stomach wall cell, fungi usually decomposition of dead organic matter and digestion and mode
of nutrient in fungi are absorption
4.correct- fungi are capable in degrading plant cellulose because they secrete cellulase enzyme to
break-down of cellulose into less complex form but in .
Fungi are a kingdom of usually multicellular eukaryotic organisms that are heterotrophs (cannot make their own food) and have important roles in nutrient cycling in an ecosystem. Fungi reproduce both sexually and asexually, and they also have symbiotic associations with plants and bacteria.

face, font size, etc. and those should be different from those of the convert buttons All textbox
text and label text should be of a reasonable size and easy to read font face. Operation The user
enters an integer value and then clicks one of the convert buttons. The 'Convert From' textbox
contents will be converted into the base. If a specific base button is used, such as octal, then no
entry in the 'Base' textbox is required. If the "Process" button is used, then the 'Base' textbox will
need to be utilized in the convert process. The escape key should exit the program and be tied to
the Exit Button using form properties only. Do not use any Native C# methods for converting
numbers into bases like Hex or Binary. Those already exist and are prohibited for this
assignment. Your program will need to convert to Binary, Hex, or any other legal base by using
only your code and the algorithm you write in your code. No calls to converting to number bases
that are already in C#. You are the one writing the conversion algorithm. All errors should be
handled without dropping into the IDE. There are error cases that need to handled and possibly
prevented by the use of validation Specifications The application should accept integer values as
entries like 3 or 48. These are to be input into the 'Convert From' textbox for the number to
convert Bases should be accepted from the range of 2 to 16, other base conversions should be
treated as an error with appropriate error messages to the user. This also means that negative
bases will not be acceptable either and need validation against them DO NOT Assume that the
user will enter valid data for the integer value. Entering a numb.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
